Cæsar adds, to prevent me from
being surprised at not hearing from you, that you were not with him when
he came to the coast (23rd of September). ”

[417] At ten miles to the east of Deal it is high tide half an hour
later than at Dover, and the reflux begins there four hours after the
hour of high tide.
[418] Those who refuse to admit Boulogne and Deal for the points of
Cæsar’s embarking and landing, pretend that so long a time was not
necessary to effect so short a passage. But a fleet requires a longer
time to navigate the more numerous it is; resembling in that an army,
which marches much more slowly than a single man.
[419] Cicero, _Epist. ad Atticum_, IV. 17.
[420] To find the time required, we must suppose that, by some delay or
by the absence of regular couriers, Cæsar’s letter to Cicero had been
thirteen days on the road between Lodi and Rome.
[421] Much uncertainty exists in regard to the distribution of the
legions; yet the location of two of the winter quarters appears to us
certain, Samarobriva (_Amiens_) and Aduatuca (_Tongres_). If now, from a
point situate near to the Sambre, from Bavay as the centre, we describe
a circle, we shall see that Cæsar’s winter quarters, except those of
Normandy, were all comprised in a radius of 100 miles, or 148
kilomètres. The researches which Major Cohausen kindly made for me, and
those of MM. Stoffel and Locqueyssie, have enabled me to determine
approximately the winter quarters.
[422] The brother of the orator.
[423] The Commandant of Artillery, De Locqueyssie, has found on the
Ourthe, near the village of Lavacherie (_Duchy of Luxemburg_), the
remains of a Roman camp with triangular fosses, and in a position which
appears to agree with the date of the “Commentaries. ”
[424] Under the name of _Belgium_, we must only comprise a part of the
peoples of Belgic Gaul, such as the Atrebates, the Ambiani, and the
Bellovaci. (_De Bello Gallico_, V. 24, 25, 46; VIII. 46. )
[425] _Unam legionem, quam proxime trans Padum
conscripserat. _--According to the use of the good Latin writers,
_proxime_ does not mean _recently_, but _in the last place_. Through an
incorrect interpretation of this phrase, General de Gœler has supposed
that Cæsar had, at this time, brought from Italy the 15th legion; this
legion, as we shall see, was only raised at a later period.
[426] More than fourteen different localities have been proposed for
identification with Aduatuca. If some writers have advanced good
arguments for placing Aduatuca on the right bank of the Meuse, others
have believed that they have offered equally good ones for seeking it on
the left bank of that river; but the greater part of them have admitted
this or that site for the most futile reasons. Nobody has dreamt of
resolving the question by the simplest of all means--which consists in
seeking if, among the different sites proposed, there is one which, by
the form of the ground, agrees with the requirements of the narrative
given in the “Commentaries. ” Now, Tongres is in this position, and it
alone, and so completely satisfies them that we cannot think of placing
Aduatuca elsewhere. In fact, Tongres is situated in the country occupied
formerly by the Eburones, and, as Cæsar expresses it, _in modiis finibus
Eburonum_, which signifies entirely in the country of the Eburones, and
not in the centre of the country. It is moreover enclosed in a circle of
a hundred miles radius, comprising all the winter quarters of the Roman
army except those of Roscius. This locality fulfils all the conditions
required for the establishment of a camp; it is near a river, on a
height which commands the neighborhood, and the country produces wheat
and forage. At two miles towards the west is a long defile, _magna
convallis_, the vale of Lowaige, where the relation of the massacre of
the cohorts of Sabinus is perfectly explained. At three miles from
Tongres we find a plain, separated from the town by a single hill; on
the same side as this hill rises a rounded eminence--that of Berg, to
which the name of tumulus may be fairly applied. Lastly, the Geer, the
banks of which were formerly marshy, defended through a large extent the
height of Tongres. (_See Plate 18. _)

[431] The towers of the Romans were constructed of timber of small size,
bound together by cross pieces. (_See Plate 27, fig. 8. _) They still
raise scaffolding at Rome in the same manner at the present day.
[432] Although the text has _passuum_, we have not hesitated in
substituting _pedum_, for it is very improbable that Gauls could have
made, in three hours’ time, a countervallation of more than 22
kilomètres.
[433] The siege machine called _testudo_, “a tortoise,” was ordinarily a
gallery mounted upon wheels, made of wood strongly squared, and covered
with a solid blindage. It was pushed against the wall of the place
besieged. It protected the workmen employed either in filling the fosse,
or in mining the wall, or in working the ram. The siege operations of
the Gauls lead us to presume that the camp of Cicero was in a fort
surrounded by a wall. (_See_, on the word _falces_, note (1) on p. 143. )
[434] In the coal-basin, in the centre of which Charleroy is situated,
the coal layers crop out of the surface of the soil on different points.
Still, at the present day, they knead the clay with small coal. But,
what is most curious, people have found at Breteuil (Oise), as in the
ruins of Carthage, a quantity of ovoid balls made of pottery.
[435] It will be seen that we use indifferently the terms _vallum_ and
_rampart_.
[436] Dio Cassius, XL. 8.
[437] It has appeared to us that the movement of concentration of Cæsar
and Fabius did not allow the winter quarters of the latter to be placed
at Therouanne or at Montreuil-sur-Mer, as most authors have supposed.
These localities are too far distant from the route from Amiens to
Charleroy to have enabled Fabius to join Cæsar on the territory of the
Atrebates, as the text of the Commentaries requires. For this reason, we
place Fabius at Saint-Pol.
[438] The “Commentaries” say, _Græcis conscriptam litteris_; but
Polyænus and Dio Cassius affirm that the letter was written in Greek.
[439] Polyænus, _Strateg. _, VIII. xxiii. 6.
[440] We admit that Cicero encamped at Charleroi: all circumstances
concur in justifying this opinion. Charleroi is situated on the Sambre,
near the Roman road from Amiens to Tongres (_Aduatuca_), and, as the
Latin text requires, at fifty miles from this latter town. On the high
part of Charleroi, where the camp was, no doubt, established, we command
the valley of the Sambre, and we can see, in the distance towards the
west, the country through which Cæsar arrived. Moreover, the valley of
the Haine and mount Sainte-Aldegonde, above the village of Carnières,
agree perfectly with the details of the combat in which the Gauls were
defeated.
[441] From Amiens to Charleroi it is 170 kilomètres. Cæsar must have
arrived on the territory of the Nervii, towards Cambrai, _the morning of
the third day_, counting from his departure from Amiens, after marching
ninety kilomètres. He immediately sends the Gaulish horseman to Cicero.
This horseman has to perform eighty kilomètres. He can only take eight
to nine hours, and arrive at the camp in the afternoon of the third day.
He throws his javelin, which remains where it was fixed _the third_ and
_the fourth day_. The _fifth_ day it was discovered, and the smoke of
the fires is then seen. Cæsar, then, arrived on the fifth day (reckoning
thirty kilomètres for a day’s march) at Binche, twenty kilomètres from
Charleroi. That town is on a sufficiently elevated knoll to allow the
smoke to be seen. The siege lasted about fifteen days.

[449] The “Commentaries,” after having informed us (V. 24) that Labienus
established himself in the country of the Remi, on the confines of that
of the Treviri, give us afterwards to understand that he encamped among
the Treviri, where he had passed the winter, “Labienum cum una legione,
quæ in eorum finibus hiemaverat. ” (VI. 7. ) We believe, with certain
authors, that the country in which he encamped was either on the
boundary of the two countries, or ground of which the Remi and the
Treviri disputed the possession. Is it not evident, moreover, that after
the catastrophe of Aduatuca and the insurrection of the people seduced
by Ambiorix, everything dictated to Labienus the necessity of engaging
himself no further in a hostile country, by separating himself from the
other legions?

[454] We must suppose from this that, during his march, Cæsar crossed
the territory of the Segni and Condrusi, or that at least he passed not
far from it. This consideration has induced us to extend this territory
farther towards the north than is generally done. (_See Plates 1 bis and
13. _)
[455] Cæsar might very well say that the Scheldt mingles his waters with
those of the Meuse. Several ancient authors share in this opinion. This
took place by the eastern arm of the Scheldt, formerly more developed
than in modern times, which spread itself in the space which, according
to Tacitus, formed the _immense mouth of the Meuse_ (_immensum Mosæ
os_).

the duty of a prudent and scrupulous general. ” (Charisius, p. 101. )
[459] _De Bello Gallico_, VI. 42.
[460] An ancient manuscript belonging to Upper Auvergne, the manuscript
of Drugeac, informs us that this custom continued long in use, and that
it still existed in the Middle Ages. Rough towers were built for this
purpose on the heights, 400 or 500 mètres apart; watchmen were placed in
them, who transmitted the news from one to another by sonorous
monosyllables. A certain number of these towers still exist in the
Cantal. If the wind prevented this mode of transmission, they had
recourse to fire.
It is evident that criers had been posted beforehand from Genabum to
Gergovia, since it was agreed that the Carnutes should give the signal
of war. It is exactly 160 miles (about 240 kilomètres), through the
valleys of the Loire and the Allier, from Gien to Gergovia, the
principal _oppidum_ of the Arverni.

[464] Their capital was Alba, now Aps (_Ardèche_). During recent
researches, remains of an ancient road have been discovered, which
passed by the places here indicated, and led from the land of the Helvi
to the Vellavi and Arverni.
[465] _De Bello Gallico_, VII. 9.
[466] Since Cæsar did not start until after the murder of Clodius, which
took place on the 13th of the Calends of February (December 30th, 701),
and had raised troops in Italy, passed through the Roman province,
penetrated over the Cévennes into Auvergne, and had thence returned to
Vienne, it is probable that he did not arrive at Sens before the
commencement of March.
[467] The Latin term has _Altero die, quum ad oppidum Senonum
Vellaunodunum venisset_, &c. All authors, without exception, considering
wrongly the expression of _altero die_ as identical with those of
_postro die_, _proximo die_, _insequenti die_, _pridie ejus diei_, have
translated it by _the following day_. We consider that _altero die_,
when used with regard to an event, signifies the second day which
follows that of the said event.
Thus Cicero gives it this sense in his _Philippica Prima_, § 13, where
he reminds us of the conduct of Antony after the death of Cæsar. Antony
had begun by treating with the conspirators who had taken refuge in the
Capitol, and, at a sitting of the Senate, which he called together _ad
hoc_, on the day of the Liberalia, that is to say, the 16th of the
Calends of April, an amnesty was pronounced in favour of the murderers
of Cæsar. Cicero, speaking of this session of the Senate, says,
_Proximo, altero, tertio, denique reliquis consecutis diebus_, &c. Is it
not evident that here _altero die_ signifies the second day which
followed the session of the Senate, or two days after that session?
Here are other examples which show that the word _alter_ must be taken
in the sense of _secundus_. Virgil says (_Eclogue_ VIII. , line 39),
_Alter ab undecimo tum jam me ceperat annus_, which must be translated,
_I was thirteen years old_. Servius, who composed a commentary on Virgil
at a time when the traditions were still preserved, makes the following
comment on this verse: _Id est tertius decimus. Alter enim de duobus
dicimus ut unus ab undecimo sit duodecimus, alter tertius decimus, et
vult significare jam se vicinum fuisse pubertati, quod de duodecimo anno
procedere non potest_. (Virgil, edit. Burmann, tom. I. , p. 130. )
Forcellini peremptorily establishes that _vicesimo altero_ signifies the
_twenty-second_; _legio altera vicesima_ means the _twenty-second
legion_.
The “Commentaries” inform us (_De Bello Civili_, III. 9) that Octavius,
when besieging Salona, had established five camps round the town, and
that the besieged took those five camps one after the other. The text is
thus expressed: _Ipsi in_ PROXIMA _Octavii castra irruperunt. Mis
expugnatis, eodem impetu_, ALTERA _sunt adorti; inde_ TERTIA _et_
QUARTA, _et deinceps_ RELIQUA. (See also _De Bello Civili_, III. 83. )
In the “Commentaries” we find sixty-three times the expression _postero
die_, thirty-six times _proximo die_, ten times _insequenti die_, eleven
times _postridie ejus diei_, or _pridie ejus diei_. The expression
_altero die_ is used only twice in the eight books _De Bello Gallico_,
viz. , lib. VII. cc. 11 and 68, and three times in _De Bello Civili_,
lib. III. cc. 19, 26, and 30. Is that coincidence alone not sufficient
to make us suppose that _altero die_ ought not to be confounded with the
preceding expressions; and does it not appear certain that, if Cæsar had
arrived at Vellaunodunum the morning after his departure from Agedincum,
he would have written, _Postero die_ (or _proximo die_) _quum ad oppidum
Senonum Vellaunodunum venisset_, &c. ?
We believe, therefore, that we are authorized in concluding that Cæsar
arrived at Vellaunodunum the second day after the army moved.
Farther on, on page 339, will be found a new confirmation of the sense
which we give to _altero die_.
It results from the appreciation of the
distance which separates Alesia from the battle-field where Cæsar
defeated the cavalry of Vercingetorix. (See the opinions of the
commentators on _altero die_ in the sixth volume of Cicero, edit.
Lemaire, Classiques Latins, _Excursus ad Philippicam primam_. )
[468] _De Bello Gallico_, VII. 11. --Contrary to the generally received
opinion, we adopt _Gien_ and not _Orleans_ for the ancient Genabum,
_Triguères_ for Vellaunodonum, _Sancerre_ for Noviodunum, and, lastly,
_Saint-Parize-le-Châtel_ for the Gorgobina of the Boii.
As Cæsar’s object, on quitting Sens, was to march as quickly as possible
to the _oppidum_ of the Boii, in order to raise the siege, since he
starts without baggage, so as to be less impeded in his march, we will
first examine the probable position of this latter town, before
discussing the question relating to the intermediate points.
_Gorgobina Boiorum_. After the defeat of the Helvetii, Cæsar allowed the
Ædui to receive the Boii upon their territory, and it is probable that
they were established on the western frontier, as in an advanced post
against the Arverni and the Bituriges. Several data confirm this
opinion. Tacitus (_Histor. _, II. 61) relates that: _Mariccus quidam, e
plebe Boiorum,. . . . concitis octo millibus hominum, proximos Æduorum
pagos trahebat_. The possessions of the Boii were, therefore, contiguous
to the Æduan territory. Pliny the Elder (_Hist. Nat. _, IV. 18) places
the Boii in the number of the nations who inhabited the centre of the
Lyonnaise. _Intus autem Ædui fœderati, Carnuti fœderati, Boii,
Senones_. . . . The place here occupied by the word _Boii_ shows us again
that this people was not far from the Ædui, the Senones, and the
Carnutes. Lastly, the text of the “Commentaries” represents
Vercingetorix as obliged to traverse the country of the Bituriges to
repair to Gorgobina. The most plausible opinion is that which places the
Boii between the Loire and the Allier, towards the confluence of these
two rivers. This was already an old tradition, adopted in the fifteenth
century by Raimondus Marlianus, one of the first editors of Cæsar. This
space of ground, covered in its eastern part with woods and marshes, was
admirably suited by its extent to the limited population of the Boii,
who did not number more than 20,000 souls. Neither
Saint-Pierre-le-Moutier, marked on the map of Gaul as Gorgobina, nor La
Guerche, proposed by General de Gœler, answer completely, by their
topographical position, to the site of a Gaulish _oppidum_. In fact,
Saint-Pierre-le-Moutier is far from being advantageously situated; this
village stands at the foot of the hills which border the right bank of
the Allier. La-Guerche-sur-Aubois fulfils no better the conditions of
defence which must be required in the principal town of the Boii: it is
situated almost in a plain, on the edge of a marshy valley of the
Aubois. It presents a few remains of fortifications of the Middle Ages,
but not a trace of more remote antiquity has been discovered in it. To
seek Gorgobina farther down, and on the left bank of the Loire, is
impossible, since, according to Cæsar, the Boii had been established on
the territory of the Ædui, and the Loire formed the boundary between the
Ædui and the Bituriges. If we are reduced to conjectures, we must at
least admit as incontestable what is advanced by Cæsar.
The village of Saint-Parize-le-Châtel suits better. It is about eight
kilomètres to the north of Saint-Pierre-le-Moutier, nearly in the middle
of the space comprised between the Loire and the Allier; it occupies the
centre of ancient agglomeration of inhabitants, which Guy Coquille, at
the end of the sixteenth century, designates under the name of the
_bourg de Gentily_, and which the _chronicles_ called, down to the
thirteenth and fourteenth centuries, _Pagus Gentilicus_, or _bourg des
gentils_. The history of this people has this remarkable peculiarity,
that, whilst all the neighbouring nations on the other side of the
Allier and the Loire had, as early as the fourth century, accepted the
Christian religion, they alone continued in idolatry until the sixth
century. Does this fact apply to a tribe settled in a foreign country,
as the Boii were, who would retain their customs and religion for a
longer time unchanged? An ancient tradition states that, in the environs
of Saint-Parize, there was, at a very remote period, a considerable
town, which was destroyed by a fire. A few scattered foundations,
discovered in the woods of Bord, to the south-west of Saint Parize, seem
to indicate the site of the _oppidum_ of the Boii. The name of the
castle, of the domain, and of the place called _Les Bruyères de Buy_,
remind us of that of the Boii.
There was probably a Roman station at Saincaise-Meauce (thirteen
kilomètres to the north of Saint-Pierre-le-Moutier), on the right bank
of the Allier. In 1861, there were discovered there numerous objects of
the Gallo-Roman period, and two busts in white marble, life-size,
representing Roman emperors. At Chantenay, eight kilomètres south from
Saint-Pierre, a few Roman foundations have been found, and a
considerable number of Gaulish coins, one of which, amongst others,
bears the name of the Æduan Litavicus.
_Genabum_. The position of Gorgobina once established at the confluence
of the Loire and the Allier, we must admit _Gien_ as the ancient
Genabum, and not _Orleans_, for the following reasons:--
1st. We cannot believe that Cæsar, leaving Sens in spite of the rigour
of the season, and in haste to raise the siege of Gorgobina, should,
without any reason, have taken a circuitous road of seventy-five
kilomètres, which would represent three or four days march, in order to
pass by Orleans. In fact, the distance from Sens to the confluence of
the Allier and the Loire, is, by Orleans, 270 kilomètres, whilst it is
only 180 kilomètres by the way of Gien.
2nd. From Sens to Gien the road was short and easy; on the contrary,
from Sens to Orleans it was necessary to pass the great marsh of Sceaux
and the forest of Orleans, probably impracticable. Now, the road
indicated on the Peutingerian Table, as leading from Orleans to Sens,
must have had a decided curve towards the south, and passed close by
Gien, after having passed through Aquæ-Segeste (_Craon_ and
_Chenevière_), for the distance between Sens and Orleans is marked at
fifty-nine Gaulish leagues, or 134 kilomètres. The Roman road, which
leads directly from Sens to Orleans, by way of Sceaux, and which the
itineraries do not mention, has only a length of 110 kilomètres: it is
certainly less ancient than the former, and can never have been a
Gaulish road.
3rd. The “Commentaries” inform us that the news of the insurrection of
Genabum arrived in a short time among the Averni (of whom Gergovia, near
Clermont, was the principal centre), at a distance of 160 miles (237
kilomètres) from Genabum. Now, the distance from Gien to Gergovia, by
the valleys of the Loire and the Allier, is 240 kilomètres, which agrees
with the text, whilst from Orleans to the same spot it is 300
kilomètres.
4th. After having crossed the Loire at Genabum, Cæsar was in the
territory of the Bituriges. This is true if he passed by Gien, and false
if he passed by Orleans, since, opposite Orleans, the left bank belonged
to the territory of the Carnutes. It is true that it has been pretended
that Gien belonged to the ancient diocese of Auxerre, and that,
consequently, it was in the territory of the Senones, and not in that of
the Carnutes. The limits of the ancient dioceses cannot be considered as
indicating in an absolute manner the frontiers of the peoples of Gaul;
and we cannot admit that the territory of the Senones formed an acute
angle upon the territory of the Carnutes, the summit of which would be
occupied by Gien. Moreover, whatever change it may have experienced in
feudal times, in regard to its diocesan attribution, Gien has never
formed a part of the Orléanais, in its civil and political relations. In
561, Gien was included in the kingdom of Orleans and Burgundy.
We believe, therefore, that Genabum was, not old Gien, which,
notwithstanding its epithet, may be posterior to Cæsar, but the present
Gien. This little town, by its position on the banks of the Loire,
besides containing a hill very appropriate for the site of an ancient
_oppidum_, possesses sufficiently interesting ruins, and agrees much
better than Old Gien with the _oppidum_ of the Carnutes. Without
attaching too great faith to traditions and etymologies, we must,
nevertheless, mention a gate at Gien, which, from time immemorial, has
been called Cæsar’s Gate (_la Porte de César_); a street called _à la
Genabye_, which leads, not towards Orleans, but towards the high part of
town; a piece of ground, situated to the north of Gien, at the angle
formed by the road to Montargis and the Roman road, at a distance of
about one kilomètre, which still preserves the name of the Field of the
Camp (_La Pièce du Camp_). Perhaps this is the spot where Cæsar placed
his camp, opposite the most accessible part of the town.
The principal reason why Orleans has been taken for Genabum is that the
Itinerary of Antoninus indicates that town under the name of _Cenabum_
or _Cenabo_, and that this name is also found in some lately discovered
inscriptions. It may be supposed that the inhabitants of Gien, after
having escaped from the destruction of their town, descended the river,
and, on the spot where Orleans now stands, formed a new establishment,
to which they gave the name of the first city; in the same manner the
inhabitants of Bibracte removed to Autun, and those of Gergovia to
Clermont.
Independently of the above considerations, Orleans, by its position on a
declivity uniformly inclined toward the Loire, does not at all answer to
the conditions of a Gaulish _oppidum_. If we admit Orleans to be
Genabum, it becomes very difficult to assign a convenient site for the
_oppida_ of Vellaunodunum and Noviodunum.
_Vellaunodunum. _ The situation of the territory of the Boii being
admitted, as well as that of Genabum, we have to find, on the road which
Cæsar pursued from Sens to Gorgobina, the intermediate points of
Vellaunodunum and Noviodunum.
On the direct line from Sens to Gien, at the distance of 40 kilomètres
from Sens, we meet with the little town of Triguères. The hill which
overlooks it from the north agrees with the position of the ancient
_oppidum_; the remains of walls, fosses, and parapets have been found on
it. Farther, there were discovered in 1856, at 500 mètres to the
north-west of Triguères, the ruins of a large semi-elliptical theatre,
capable of containing from 5,000 to 6,000 spectators. In another
direction, the ruins of a Druidical monument have been pointed out; in
fact, everything leads to the belief that there existed at Triguères, in
the Gallo-Roman period, an important centre, which had been preceded by
a Gaulish establishment anterior to the conquest. A road paved with
stones, considered by some as a Gaulish or Celtic way, but accepted by
all archæologists as a Roman road, goes direct from Sens to Triguères,
by Courtenay, and passes along the eastern side of the _oppidum_.
Another ancient way leads similarly from Triguères to Gien. We feel no
hesitation, after what precedes, in placing Vellaunodunum at Triguères.
It will be objected that the distance from Sens to this little town (40
kilomètres) is too small to have taken the Roman army, without baggage,
three days’ march; but Cæsar does not say that he employed three days in
proceeding from _Agedincum_ to _Vellaunodunum_: he informs us merely
that, leaving all his baggage at Agedincum, he journeyed towards the
country of the Boii, and that on the second day he arrived at
Vellaunodunum. Nothing, therefore, obliges us to suppose that, before it
marched, the Roman army was concentrated or encamped at Agedincum
itself. Persons unacquainted with military art are apt to suppose that
an army lives and marches always concentrated on one point.
Cæsar, although he was effecting the concentration of his troops before
entering into campaign, did not keep them massed at the gates of Sens,
but he probably distributed them in _échelon_ in the neighbourhood of
the town, along the Yonne. When afterwards he decided on marching to the
succour of the Boii, we must suppose that the first day was employed in
concentrating the whole army at Sens itself, in leaving the baggage
there, perhaps also in crossing the Yonne, a long operation for more
than 60,000 men. The first day having passed, the army continued its
march next day, and arrived at Triguères the day following, having
performed two days’ march of 20 kilomètres each. We see, then, that the
distance between Sens and Triguères does not prevent us from identifying
this latter locality with Vellaunodunum. Triguères is distant 44
kilomètres from Gien, the distance which separated Vellaunodunum from
Genabum, and which might have been marched in two days.
_Noviodunum. _ To find the site of Noviodunum, we must seek a position
which agrees best with the “Commentaries” in the triangle formed by the
three known points, Gien, Le Bec-d’Allier, and Bourges. Since, according
to the text, Vercingetorix did not raise the siege of the town of the
Boii until he had heard of Cæsar’s arrival on the left bank of the
Loire, and since the two hostile armies, marching towards each other,
met at Noviodunum, it follows that this last-named town must be about
half-way between the spot where the Loire was passed and the town of the
Boii; on another hand, since Cæsar took several days to reach Bourges
from Noviodunum, there must have been a rather considerable distance
between those two last-named towns. Moreover, in order that the
inhabitants of Noviodunum should have seen in the distance, from the top
of their walls, the cavalry of Vercingetorix, the town must necessarily
have been situated on an eminence. Lastly, the cavalry combat, fought at
a small distance from the town, proves that the ground was sufficiently
flat to permit that engagement.
It is, therefore, because certain points hitherto indicated do not
answer to the conditions required by the text, that we have not
admitted, as representing Noviodunum, the towns of Nouan-le-Fuselier,
Pierrefitte-sur-Saudre, Nohant-en-Goût, Neuvy-en-Sullias, or
Neuvy-sur-Barangeon. In fact, some of these are too far from
Bec-d’Allier, while others are too near Bourges, and most of them are
situated in a plain.
Sancerre, on the contrary, answers all the conditions of the text. It is
situated on a hill which rises 115 mètres above the valley watered by
the Loire. Encircled on all sides by deep ravines, it can only be
approached from one point, situated to the east, where the ancient Roman
road of Bourges terminated, which is still at the present day called the
Big Road (_le Gros Chemin_). The Abbé Lebœuf, as early as 1727, had
designated this town as the ancient Noviodunum. It is near Saint-Satur,
at the very foot of the mountain of Sancerre, that a Gallo-Roman town
existed, of which, within the last few years, numerous foundations have
been found. It is probable that this Gallo-Roman town had succeeded to a
great centre of Gaulish population, for the Bituriges must necessarily
have occupied in their territory a point so admirably fortified by
nature, and which commanded the course of the Loire, the line of
boundary between them and the Ædui. The present town seems to have kept
within the very limits of the ancient _oppidum_; it has the form of an
ellipse of from 700 to 800 mètres in length on a breadth of about 500
mètres, capable of containing a population of from 4,000 to 5,000
inhabitants. At Sancerre there was also, at the extremity of one of the
streets, towards the north, a gate called the Gate of Cæsar (_Porte de
César_), which was demolished in the beginning of the nineteenth
century. By adopting Sancerre, all the movements of the commencement of
the campaign of 702 are easily explained. This town is forty-six
kilomètres from Gien, forty-eight kilomètres from Le Bec-d’Allier,
distances nearly equal, so that Vercingetorix and Cæsar, starting almost
at the same time from two opposite points, may have met under its walls.
Its elevated position allowed the eye to range far towards the south
along the valley of the Loire, through which the inhabitants would have
seen the approach of the cavalry of Vercingetorix. Cæsar may have
occupied with his army the heights of Verdigny or Saint-Satur, to the
north of Sancerre. A cavalry engagement may have taken place in the
valley of Saint-Satur, or on the plain between Ménétréol and
Saint-Thibaud. The captain of staff Rouby has examined with the greatest
care the places just mentioned.
Cæsar, after the surrender of Noviodunum, marches towards Bourges.
Vercingetorix follows him by short marches (_minoribus itineribus_). The
Roman general, having Bourges before him, and a hostile army on his
left, marches slowly and with precaution. Perhaps he took three or four
days to perform the forty-five kilomètres which separate Sancerre from
Bourges. At last, after having reconnoitred the site of Avaricum, he
must have traversed the marshes of the Yèvre, at a distance of three or
four kilomètres from that town, so as to take up a position to the
south-east of the _oppidum_, in that part which was not surrounded by
the river and the marshes, and which only offered a narrow passage. As
to Vercingetorix, he follows, or rather hovers on, the Roman army,
taking up his position on its left, and still keeping up his
communication with Avaricum, hesitating whether he shall deliver it to
the flames.
[469] _De Bello Gallico_, VII. 13.
[470] Archælogists have pretended they find traces still existing of the
camp of Vercingetorix in the neighbourhood of Bourges, not considering
that Cæsar declares that the Gaulish chief did not, for the first time,
think of retrenching his camp in the Roman fashion till after the siege
of this town. We believe that Vercingetorix, although he came from the
east, encamped to the south of Bourges. It was, indeed, natural that he
should place himself between the Roman army and the land of the Arverni,
whence, probably, it drew its provisions. Besides, if he had placed his
camp to the east of Bourges, he would have intercepted the provisions
which Cæsar expected from the land of the Ædui, which the text does not
say.
[471] The ravine which descends to the Auron is still recognised at the
present day, between the Portes Saint-Michel and Saint-Paul, by the
sudden incline of the ground. Old plans of Bourges designate it by the
name of the _Vallée Saint-Paul_. The opposite ravine, which runs towards
the Porte Bourbonnoux, has disappeared under the successive fillings up
composing the soil of the garden of the archbishop’s palace. The ridge
of land forming the avenue cannot have been in Cæsar’s time more than
100 mètres broad. It has lost its primitive physiognomy, especially by
the formation of the Place Sérancourt, in 1700, on a site the level of
which did not then exceed that of the field of the present fair. The
depression of the ground which existed before the wall is more visible;
it has been filled-up during the different sieges of Bourges.
[472] This is evident, since the Romans, in order to be able to give the
assault, were obliged to construct a terrace eighty feet high. General
de Gœler believed this measurement exaggerated. Nevertheless, as this
terrace was constructed in a ravine, it was necessary that it should
compensate a difference of level of eighty mètres, of which thirty,
perhaps, represent the height of the wall.
[473] Vercingetorix, encamped first towards Dun-le-Roi, had approached
nearer Bourges. He had established his new camp to the east of that of
Cæsar, perhaps at La Chenevière, at the confluence of the Yèvre and the
brook of Villabon, fourteen kilomètres from Bourges.
[474] See the quotation from Vegetius, p. 143, note (1).
[475] We read in Vitruvius, on occasion of the siege of Marseilles:
“When the tortoise approached to batter the wall, they let down a cord
furnished with a slip-knot, in which they caught the ram, and raised its
head so high, by means of a wheel, that they prevented its striking the
wall. ” (Vitruvius, X. 16. )
[476] Titus Livius expresses himself thus in speaking of the beseiged in
Ambracia, who dug a mine to meet that of the enemies: “Aperiunt viam
rectam in cuniculum. ” (XXXVII. 7. )
[477] Several authors have thought that these beams, instead of being
placed perpendicularly to the direction of the wall, were placed
parallel to that direction. This interpretation appears to us
inadmissable. The beams so placed would have no solidity, and would
easily have been torn down. We see on the Trajan Column walls
constructed as we describe; moreover, the Latin expression _trabes
directæ_ can leave no doubt, for the word _directus_ means always
_perpendicular to a direction_. (See _De Bello Gallico_, IV. 17,
_directa materia injecta_, and the dissertation in the _Philologus_,
Jahrganges 19, Heft. 3. )
[478] The name of _pluteus_ was given generally to all kinds of covering
with hurdles or with skins. (Festus, in voce _Pluteus_. --Vitruvius, X.
20. )--Vegetius (IV. 15) applies the name of _pluteus_ to a kind of
penthouse, of wicker-work or skins, mounted on three wheels, and
protecting the men placed behind it, so that they might shoot at the
defenders.
[479] They gave this name to a small engine resembling the balistæ,
which threw darts. These scorpions composed, as it were, the
field-artillery of the ancients.
[480] _De Bello Gallico_, VII. 32.
[481] It is very probably that Cæsar proceeded first to Noviodunum
(_Nevers_), since he informs us that he had established in that town a
great magazine and provisions of every kind.
[482] At present the Allier is fordable almost everywhere in summer; but
in the course of nineteen centuries the bed of the river must have been
considerably raised.
[483] The commentators are not agreed on this passage. I have adopted
the version which seemed to me the best, and which MM. Köchly and Rustow
have followed in their German translation, Stuttgart, 1862.
[484] Dio Cassius, XL. 35.
[485] Cæsar, on leaving Decize, followed, no doubt the Gaulish road
which led to the Allier, and the existence of which may be assumed from
the later construction of the Roman road which goes from Decize to
Bourbon-l’Archambault (_Aquæ Borvonis_), and which crossed the Allier a
little below Moulins. Thence he followed the course of the river for
some days, constantly in face of the enemy. In order to pass it by the
help of a stratagem, he took advantage of the remains of a bridge; and,
as this bridge indicates that there must have been a road, it becomes a
question to find among the ancient roads which crossed the Allier that
which Cæsar followed. Now we only know two Roman roads leading to the
Allier below Moulins, one at Varennes, the other at Vichy. We adopt
Varennes. That locality is seventy-seven kilomètres from Gergovia,
reckoning them along the Allier, and Cæsar took five days to perform
them; but, as the four legions sent forward to deceive the enemy
returned during the night, in order to rejoin him, they must have
suffered great fatigues; hence it is to be presumed that the next day
the first march was very short. The fifth also was not long, for,
according to the “Commentaries,” Cæsar had time on the day of his
arrival to fortify his camp, to reconnoitre the place, and to engage in
a cavalry combat. Besides, the country, interspersed with woods and
marshes, was unknown to him; and we believe that we do not depart from
the truth if we admit that the first and the last march were of no more
than ten kilomètres, and the three others of nineteen, which gives a
total of seventy-seven kilomètres, the distance from Varennes to
Gergovia. When Cæsar left Gergovia, he crossed the Allier again, but at
a point nearer to Gergovia, being in haste to place the river between
him and the enemy. Indeed, on the second day after his check, he fought
a successful cavalry engagement, broke up his camp, and the following
day (_tertio die_) crossed the Allier again, according to our opinion,
at Vichy, which is only fifty-five kilomètres from Gergovia.
[486] The Artières receives, on the north of Gergovia, the little brook
of Clémensat, marked on _Plate 21_.
[487] It is by seeking the essential conditions required for the placing
of troops that Commandant Baron Stoffel succeeded in finding the camps.
Cæsar had to place from 30,000 to 40,000 men in the neighbourhood of
water, at a convenient distance from Gergovia, and in such a manner as
to preserve his line of operation upon Nevers, where his magazines were.
These necessities indicated that the principal camp would be near the
Auzon, and to the east. Moreover, it must be sufficiently near the
_oppidum_, that from the top of the mountain of Gergovia could be seen
what was going on in it; and yet sufficiently distant that the objects
could not be clearly distinguished. The camp must be in the plain; Dio
Cassius (XL. 36) formally says, “Cæsar remained in the plain, not having
been able to take (for placing his camp) a place strong by its
elevation;” and then the “Commentaries” inform us that the Romans only
occupied one single hill, namely, the one they took by surprise (La
Roche-Blanche). Lastly, it was indispensable that there should be in
front of the camp a space sufficiently large to admit of cavalry
engagements.
[488] Vercingetorix, placed in the centre of a kind of semicircle, might
easily be considered by Cæsar as surrounded by his numerous troops
(_collocaverat copias circum se_).
[489] The combats of cavalry took place in the plain which extends from
the small eminence called _Le Puy-de-Marmant_ to the marsh of Sarlièves.
[490] The hill is certainly the Roche-Blanche, for it is situated
opposite the _oppidum_ (_e regione oppidi_); it begins at the very foot
of the slopes of the mountain of Gergovia (_sub ipsis radicibus
montis_), is singularly fortified by nature, and, as it were, cut out
from all sides (_egregie munitus atque ex omni parte circumcisus_). So
long as the Gauls occupied it, they could go to the Auzon by the ravine
of Merdogne, to obtain water and forage; but as soon as it was in the
power of the Romans, the Gauls were compelled to draw their water from
the springs on the mountain of Gergovia, and from the little brook of
Artières.
The excavations made in 1862 brought the two camps to light. The fosses
of the little camp are clearly defined in the calcareous soil. They form
an irregular outline, represented on _Plate 22_. The Roche-Blanche,
which presents in its southern part an escarpment almost as
perpendicular as a wall, has lost on the sides its abrupt form by
successive landslips, the last of which took place within memory of the
inhabitants. The communication between the great and little camps was
composed of a parapet, formed by the earth thrown out of two contiguous
fosses, each four feet in depth and six in breadth, so that the breadth
of the two together is only twelve feet. If we wonder that the Romans
should have dug two little ditches, each six feet broad and four feet
deep, instead of making one eight feet wide by six feet deep, which
would have given the same amount of soil to take out, it may be answered
that the two little ditches were much more quickly made than one large
ditch.

[492] _Plate 22_ shows the places which Cæsar’s eye could embrace from
the summit of the Roche-Blanche. He could see neither the plateau, nor
the country situated on the norther slopes of the mountains of Gergovia
and Rissoles. It was for this reason that he had to learn from the
deserters the form of the ground which lay on the other side. He thus
learnt that the ridge of this latter mountain (_dorsum ejus jugi_) was
not very uneven, and gave access to the western part of the town (_ad
alteram partem oppidi_) by a narrow wooded passage (the defile of the
Goules, which separates Rissoles from Gergovia). (_See Plate 21 in C. _)
This defile leads to the gate _P_ of the _oppidum_.
being surprised at not hearing from you, that you were not with him when
he came to the coast (23rd of September). ”
[416] Cicero, _Epist. ad Quintum_, III. 3.
[417] At ten miles to the east of Deal it is high tide half an hour
later than at Dover, and the reflux begins there four hours after the
hour of high tide.
[418] Those who refuse to admit Boulogne and Deal for the points of
Cæsar’s embarking and landing, pretend that so long a time was not
necessary to effect so short a passage. But a fleet requires a longer
time to navigate the more numerous it is; resembling in that an army,
which marches much more slowly than a single man.
[419] Cicero, _Epist. ad Atticum_, IV. 17.
[420] To find the time required, we must suppose that, by some delay or
by the absence of regular couriers, Cæsar’s letter to Cicero had been
thirteen days on the road between Lodi and Rome.
[421] Much uncertainty exists in regard to the distribution of the
legions; yet the location of two of the winter quarters appears to us
certain, Samarobriva (_Amiens_) and Aduatuca (_Tongres_). If now, from a
point situate near to the Sambre, from Bavay as the centre, we describe
a circle, we shall see that Cæsar’s winter quarters, except those of
Normandy, were all comprised in a radius of 100 miles, or 148
kilomètres. The researches which Major Cohausen kindly made for me, and
those of MM. Stoffel and Locqueyssie, have enabled me to determine
approximately the winter quarters.
[422] The brother of the orator.
[423] The Commandant of Artillery, De Locqueyssie, has found on the
Ourthe, near the village of Lavacherie (_Duchy of Luxemburg_), the
remains of a Roman camp with triangular fosses, and in a position which
appears to agree with the date of the “Commentaries. ”
[424] Under the name of _Belgium_, we must only comprise a part of the
peoples of Belgic Gaul, such as the Atrebates, the Ambiani, and the
Bellovaci. (_De Bello Gallico_, V. 24, 25, 46; VIII. 46. )
[425] _Unam legionem, quam proxime trans Padum
conscripserat. _--According to the use of the good Latin writers,
_proxime_ does not mean _recently_, but _in the last place_. Through an
incorrect interpretation of this phrase, General de Gœler has supposed
that Cæsar had, at this time, brought from Italy the 15th legion; this
legion, as we shall see, was only raised at a later period.
[426] More than fourteen different localities have been proposed for
identification with Aduatuca. If some writers have advanced good
arguments for placing Aduatuca on the right bank of the Meuse, others
have believed that they have offered equally good ones for seeking it on
the left bank of that river; but the greater part of them have admitted
this or that site for the most futile reasons. Nobody has dreamt of
resolving the question by the simplest of all means--which consists in
seeking if, among the different sites proposed, there is one which, by
the form of the ground, agrees with the requirements of the narrative
given in the “Commentaries. ” Now, Tongres is in this position, and it
alone, and so completely satisfies them that we cannot think of placing
Aduatuca elsewhere. In fact, Tongres is situated in the country occupied
formerly by the Eburones, and, as Cæsar expresses it, _in modiis finibus
Eburonum_, which signifies entirely in the country of the Eburones, and
not in the centre of the country. It is moreover enclosed in a circle of
a hundred miles radius, comprising all the winter quarters of the Roman
army except those of Roscius. This locality fulfils all the conditions
required for the establishment of a camp; it is near a river, on a
height which commands the neighborhood, and the country produces wheat
and forage. At two miles towards the west is a long defile, _magna
convallis_, the vale of Lowaige, where the relation of the massacre of
the cohorts of Sabinus is perfectly explained. At three miles from
Tongres we find a plain, separated from the town by a single hill; on
the same side as this hill rises a rounded eminence--that of Berg, to
which the name of tumulus may be fairly applied. Lastly, the Geer, the
banks of which were formerly marshy, defended through a large extent the
height of Tongres. (_See Plate 18. _)
[427] _De Bello Gallico_, V. 25.
[428] See the notice by M. M. F. Driesen on the position of Aduatuca, in
the _Bulletins de l’Académie Royale de Belgique_, 2nd series, tom. XV.
No. 3.
[429] _De Bello Gallico_, V. 37.

[431] The towers of the Romans were constructed of timber of small size,
bound together by cross pieces. (_See Plate 27, fig. 8. _) They still
raise scaffolding at Rome in the same manner at the present day.
[432] Although the text has _passuum_, we have not hesitated in
substituting _pedum_, for it is very improbable that Gauls could have
made, in three hours’ time, a countervallation of more than 22
kilomètres.
[433] The siege machine called _testudo_, “a tortoise,” was ordinarily a
gallery mounted upon wheels, made of wood strongly squared, and covered
with a solid blindage. It was pushed against the wall of the place
besieged. It protected the workmen employed either in filling the fosse,
or in mining the wall, or in working the ram. The siege operations of
the Gauls lead us to presume that the camp of Cicero was in a fort
surrounded by a wall. (_See_, on the word _falces_, note (1) on p. 143. )
[434] In the coal-basin, in the centre of which Charleroy is situated,
the coal layers crop out of the surface of the soil on different points.
Still, at the present day, they knead the clay with small coal. But,
what is most curious, people have found at Breteuil (Oise), as in the
ruins of Carthage, a quantity of ovoid balls made of pottery.
[435] It will be seen that we use indifferently the terms _vallum_ and
_rampart_.
[436] Dio Cassius, XL. 8.
[437] It has appeared to us that the movement of concentration of Cæsar
and Fabius did not allow the winter quarters of the latter to be placed
at Therouanne or at Montreuil-sur-Mer, as most authors have supposed.
These localities are too far distant from the route from Amiens to
Charleroy to have enabled Fabius to join Cæsar on the territory of the
Atrebates, as the text of the Commentaries requires. For this reason, we
place Fabius at Saint-Pol.
[438] The “Commentaries” say, _Græcis conscriptam litteris_; but
Polyænus and Dio Cassius affirm that the letter was written in Greek.
[439] Polyænus, _Strateg. _, VIII. xxiii. 6.
[440] We admit that Cicero encamped at Charleroi: all circumstances
concur in justifying this opinion. Charleroi is situated on the Sambre,
near the Roman road from Amiens to Tongres (_Aduatuca_), and, as the
Latin text requires, at fifty miles from this latter town. On the high
part of Charleroi, where the camp was, no doubt, established, we command
the valley of the Sambre, and we can see, in the distance towards the
west, the country through which Cæsar arrived. Moreover, the valley of
the Haine and mount Sainte-Aldegonde, above the village of Carnières,
agree perfectly with the details of the combat in which the Gauls were
defeated.
[441] From Amiens to Charleroi it is 170 kilomètres. Cæsar must have
arrived on the territory of the Nervii, towards Cambrai, _the morning of
the third day_, counting from his departure from Amiens, after marching
ninety kilomètres. He immediately sends the Gaulish horseman to Cicero.
This horseman has to perform eighty kilomètres. He can only take eight
to nine hours, and arrive at the camp in the afternoon of the third day.
He throws his javelin, which remains where it was fixed _the third_ and
_the fourth day_. The _fifth_ day it was discovered, and the smoke of
the fires is then seen. Cæsar, then, arrived on the fifth day (reckoning
thirty kilomètres for a day’s march) at Binche, twenty kilomètres from
Charleroi. That town is on a sufficiently elevated knoll to allow the
smoke to be seen. The siege lasted about fifteen days.

[449] The “Commentaries,” after having informed us (V. 24) that Labienus
established himself in the country of the Remi, on the confines of that
of the Treviri, give us afterwards to understand that he encamped among
the Treviri, where he had passed the winter, “Labienum cum una legione,
quæ in eorum finibus hiemaverat. ” (VI. 7. ) We believe, with certain
authors, that the country in which he encamped was either on the
boundary of the two countries, or ground of which the Remi and the
Treviri disputed the possession. Is it not evident, moreover, that after
the catastrophe of Aduatuca and the insurrection of the people seduced
by Ambiorix, everything dictated to Labienus the necessity of engaging
himself no further in a hostile country, by separating himself from the
other legions?

[454] We must suppose from this that, during his march, Cæsar crossed
the territory of the Segni and Condrusi, or that at least he passed not
far from it. This consideration has induced us to extend this territory
farther towards the north than is generally done. (_See Plates 1 bis and
13. _)
[455] Cæsar might very well say that the Scheldt mingles his waters with
those of the Meuse. Several ancient authors share in this opinion. This
took place by the eastern arm of the Scheldt, formerly more developed
than in modern times, which spread itself in the space which, according
to Tacitus, formed the _immense mouth of the Meuse_ (_immensum Mosæ
os_).
[456] _De Bello Gallico_, VI. 34.
[457] Forty-five kilomètres reckoned down from Bonn bring us to the
confluence of the Wipper and the Rhine.
[458] Cæsar complained of the conduct of Quintus, when he wrote to
Cicero the orator: “He did not keep within the camp, as would have been
the duty of a prudent and scrupulous general. ” (Charisius, p. 101. )
[459] _De Bello Gallico_, VI. 42.
[460] An ancient manuscript belonging to Upper Auvergne, the manuscript
of Drugeac, informs us that this custom continued long in use, and that
it still existed in the Middle Ages. Rough towers were built for this
purpose on the heights, 400 or 500 mètres apart; watchmen were placed in
them, who transmitted the news from one to another by sonorous
monosyllables. A certain number of these towers still exist in the
Cantal. If the wind prevented this mode of transmission, they had
recourse to fire.
It is evident that criers had been posted beforehand from Genabum to
Gergovia, since it was agreed that the Carnutes should give the signal
of war. It is exactly 160 miles (about 240 kilomètres), through the
valleys of the Loire and the Allier, from Gien to Gergovia, the
principal _oppidum_ of the Arverni.
[461] “Hic corpore, armis, spirituque terribilis, nomine etiam quasi ad
terrorem composito. ” (Florus, II. x. 21. )--Vercingetorix was born at
Gergovia. (Strabo, IV. , p. 158. )

[463] Coins of Lucterius have been found, as well as of many of the
Gaulish chiefs mentioned in the “Commentaries. ” The first has been
described by MM. [“Messieurs” methinks] Mionet and Chaudruc de Crazannes.
(_Revue Numismatique_, t. V. , pl. 16, p. 333. )
[464] Their capital was Alba, now Aps (_Ardèche_). During recent
researches, remains of an ancient road have been discovered, which
passed by the places here indicated, and led from the land of the Helvi
to the Vellavi and Arverni.
[465] _De Bello Gallico_, VII. 9.
[466] Since Cæsar did not start until after the murder of Clodius, which
took place on the 13th of the Calends of February (December 30th, 701),
and had raised troops in Italy, passed through the Roman province,
penetrated over the Cévennes into Auvergne, and had thence returned to
Vienne, it is probable that he did not arrive at Sens before the
commencement of March.
[467] The Latin term has _Altero die, quum ad oppidum Senonum
Vellaunodunum venisset_, &c. All authors, without exception, considering
wrongly the expression of _altero die_ as identical with those of
_postro die_, _proximo die_, _insequenti die_, _pridie ejus diei_, have
translated it by _the following day_. We consider that _altero die_,
when used with regard to an event, signifies the second day which
follows that of the said event.
Thus Cicero gives it this sense in his _Philippica Prima_, § 13, where
he reminds us of the conduct of Antony after the death of Cæsar. Antony
had begun by treating with the conspirators who had taken refuge in the
Capitol, and, at a sitting of the Senate, which he called together _ad
hoc_, on the day of the Liberalia, that is to say, the 16th of the
Calends of April, an amnesty was pronounced in favour of the murderers
of Cæsar. Cicero, speaking of this session of the Senate, says,
_Proximo, altero, tertio, denique reliquis consecutis diebus_, &c. Is it
not evident that here _altero die_ signifies the second day which
followed the session of the Senate, or two days after that session?
Here are other examples which show that the word _alter_ must be taken
in the sense of _secundus_. Virgil says (_Eclogue_ VIII. , line 39),
_Alter ab undecimo tum jam me ceperat annus_, which must be translated,
_I was thirteen years old_. Servius, who composed a commentary on Virgil
at a time when the traditions were still preserved, makes the following
comment on this verse: _Id est tertius decimus. Alter enim de duobus
dicimus ut unus ab undecimo sit duodecimus, alter tertius decimus, et
vult significare jam se vicinum fuisse pubertati, quod de duodecimo anno
procedere non potest_. (Virgil, edit. Burmann, tom. I. , p. 130. )
Forcellini peremptorily establishes that _vicesimo altero_ signifies the
_twenty-second_; _legio altera vicesima_ means the _twenty-second
legion_.
The “Commentaries” inform us (_De Bello Civili_, III. 9) that Octavius,
when besieging Salona, had established five camps round the town, and
that the besieged took those five camps one after the other. The text is
thus expressed: _Ipsi in_ PROXIMA _Octavii castra irruperunt. Mis
expugnatis, eodem impetu_, ALTERA _sunt adorti; inde_ TERTIA _et_
QUARTA, _et deinceps_ RELIQUA. (See also _De Bello Civili_, III. 83. )
In the “Commentaries” we find sixty-three times the expression _postero
die_, thirty-six times _proximo die_, ten times _insequenti die_, eleven
times _postridie ejus diei_, or _pridie ejus diei_. The expression
_altero die_ is used only twice in the eight books _De Bello Gallico_,
viz. , lib. VII. cc. 11 and 68, and three times in _De Bello Civili_,
lib. III. cc. 19, 26, and 30. Is that coincidence alone not sufficient
to make us suppose that _altero die_ ought not to be confounded with the
preceding expressions; and does it not appear certain that, if Cæsar had
arrived at Vellaunodunum the morning after his departure from Agedincum,
he would have written, _Postero die_ (or _proximo die_) _quum ad oppidum
Senonum Vellaunodunum venisset_, &c. ?
We believe, therefore, that we are authorized in concluding that Cæsar
arrived at Vellaunodunum the second day after the army moved.
Farther on, on page 339, will be found a new confirmation of the sense
which we give to _altero die_.
It results from the appreciation of the
distance which separates Alesia from the battle-field where Cæsar
defeated the cavalry of Vercingetorix. (See the opinions of the
commentators on _altero die_ in the sixth volume of Cicero, edit.
Lemaire, Classiques Latins, _Excursus ad Philippicam primam_. )
[468] _De Bello Gallico_, VII. 11. --Contrary to the generally received
opinion, we adopt _Gien_ and not _Orleans_ for the ancient Genabum,
_Triguères_ for Vellaunodonum, _Sancerre_ for Noviodunum, and, lastly,
_Saint-Parize-le-Châtel_ for the Gorgobina of the Boii.
As Cæsar’s object, on quitting Sens, was to march as quickly as possible
to the _oppidum_ of the Boii, in order to raise the siege, since he
starts without baggage, so as to be less impeded in his march, we will
first examine the probable position of this latter town, before
discussing the question relating to the intermediate points.
_Gorgobina Boiorum_. After the defeat of the Helvetii, Cæsar allowed the
Ædui to receive the Boii upon their territory, and it is probable that
they were established on the western frontier, as in an advanced post
against the Arverni and the Bituriges. Several data confirm this
opinion. Tacitus (_Histor. _, II. 61) relates that: _Mariccus quidam, e
plebe Boiorum,. . . . concitis octo millibus hominum, proximos Æduorum
pagos trahebat_. The possessions of the Boii were, therefore, contiguous
to the Æduan territory. Pliny the Elder (_Hist. Nat. _, IV. 18) places
the Boii in the number of the nations who inhabited the centre of the
Lyonnaise. _Intus autem Ædui fœderati, Carnuti fœderati, Boii,
Senones_. . . . The place here occupied by the word _Boii_ shows us again
that this people was not far from the Ædui, the Senones, and the
Carnutes. Lastly, the text of the “Commentaries” represents
Vercingetorix as obliged to traverse the country of the Bituriges to
repair to Gorgobina. The most plausible opinion is that which places the
Boii between the Loire and the Allier, towards the confluence of these
two rivers. This was already an old tradition, adopted in the fifteenth
century by Raimondus Marlianus, one of the first editors of Cæsar. This
space of ground, covered in its eastern part with woods and marshes, was
admirably suited by its extent to the limited population of the Boii,
who did not number more than 20,000 souls. Neither
Saint-Pierre-le-Moutier, marked on the map of Gaul as Gorgobina, nor La
Guerche, proposed by General de Gœler, answer completely, by their
topographical position, to the site of a Gaulish _oppidum_. In fact,
Saint-Pierre-le-Moutier is far from being advantageously situated; this
village stands at the foot of the hills which border the right bank of
the Allier. La-Guerche-sur-Aubois fulfils no better the conditions of
defence which must be required in the principal town of the Boii: it is
situated almost in a plain, on the edge of a marshy valley of the
Aubois. It presents a few remains of fortifications of the Middle Ages,
but not a trace of more remote antiquity has been discovered in it. To
seek Gorgobina farther down, and on the left bank of the Loire, is
impossible, since, according to Cæsar, the Boii had been established on
the territory of the Ædui, and the Loire formed the boundary between the
Ædui and the Bituriges. If we are reduced to conjectures, we must at
least admit as incontestable what is advanced by Cæsar.
The village of Saint-Parize-le-Châtel suits better. It is about eight
kilomètres to the north of Saint-Pierre-le-Moutier, nearly in the middle
of the space comprised between the Loire and the Allier; it occupies the
centre of ancient agglomeration of inhabitants, which Guy Coquille, at
the end of the sixteenth century, designates under the name of the
_bourg de Gentily_, and which the _chronicles_ called, down to the
thirteenth and fourteenth centuries, _Pagus Gentilicus_, or _bourg des
gentils_. The history of this people has this remarkable peculiarity,
that, whilst all the neighbouring nations on the other side of the
Allier and the Loire had, as early as the fourth century, accepted the
Christian religion, they alone continued in idolatry until the sixth
century. Does this fact apply to a tribe settled in a foreign country,
as the Boii were, who would retain their customs and religion for a
longer time unchanged? An ancient tradition states that, in the environs
of Saint-Parize, there was, at a very remote period, a considerable
town, which was destroyed by a fire. A few scattered foundations,
discovered in the woods of Bord, to the south-west of Saint Parize, seem
to indicate the site of the _oppidum_ of the Boii. The name of the
castle, of the domain, and of the place called _Les Bruyères de Buy_,
remind us of that of the Boii.
There was probably a Roman station at Saincaise-Meauce (thirteen
kilomètres to the north of Saint-Pierre-le-Moutier), on the right bank
of the Allier. In 1861, there were discovered there numerous objects of
the Gallo-Roman period, and two busts in white marble, life-size,
representing Roman emperors. At Chantenay, eight kilomètres south from
Saint-Pierre, a few Roman foundations have been found, and a
considerable number of Gaulish coins, one of which, amongst others,
bears the name of the Æduan Litavicus.
_Genabum_. The position of Gorgobina once established at the confluence
of the Loire and the Allier, we must admit _Gien_ as the ancient
Genabum, and not _Orleans_, for the following reasons:--
1st. We cannot believe that Cæsar, leaving Sens in spite of the rigour
of the season, and in haste to raise the siege of Gorgobina, should,
without any reason, have taken a circuitous road of seventy-five
kilomètres, which would represent three or four days march, in order to
pass by Orleans. In fact, the distance from Sens to the confluence of
the Allier and the Loire, is, by Orleans, 270 kilomètres, whilst it is
only 180 kilomètres by the way of Gien.
2nd. From Sens to Gien the road was short and easy; on the contrary,
from Sens to Orleans it was necessary to pass the great marsh of Sceaux
and the forest of Orleans, probably impracticable. Now, the road
indicated on the Peutingerian Table, as leading from Orleans to Sens,
must have had a decided curve towards the south, and passed close by
Gien, after having passed through Aquæ-Segeste (_Craon_ and
_Chenevière_), for the distance between Sens and Orleans is marked at
fifty-nine Gaulish leagues, or 134 kilomètres. The Roman road, which
leads directly from Sens to Orleans, by way of Sceaux, and which the
itineraries do not mention, has only a length of 110 kilomètres: it is
certainly less ancient than the former, and can never have been a
Gaulish road.
3rd. The “Commentaries” inform us that the news of the insurrection of
Genabum arrived in a short time among the Averni (of whom Gergovia, near
Clermont, was the principal centre), at a distance of 160 miles (237
kilomètres) from Genabum. Now, the distance from Gien to Gergovia, by
the valleys of the Loire and the Allier, is 240 kilomètres, which agrees
with the text, whilst from Orleans to the same spot it is 300
kilomètres.
4th. After having crossed the Loire at Genabum, Cæsar was in the
territory of the Bituriges. This is true if he passed by Gien, and false
if he passed by Orleans, since, opposite Orleans, the left bank belonged
to the territory of the Carnutes. It is true that it has been pretended
that Gien belonged to the ancient diocese of Auxerre, and that,
consequently, it was in the territory of the Senones, and not in that of
the Carnutes. The limits of the ancient dioceses cannot be considered as
indicating in an absolute manner the frontiers of the peoples of Gaul;
and we cannot admit that the territory of the Senones formed an acute
angle upon the territory of the Carnutes, the summit of which would be
occupied by Gien. Moreover, whatever change it may have experienced in
feudal times, in regard to its diocesan attribution, Gien has never
formed a part of the Orléanais, in its civil and political relations. In
561, Gien was included in the kingdom of Orleans and Burgundy.
We believe, therefore, that Genabum was, not old Gien, which,
notwithstanding its epithet, may be posterior to Cæsar, but the present
Gien. This little town, by its position on the banks of the Loire,
besides containing a hill very appropriate for the site of an ancient
_oppidum_, possesses sufficiently interesting ruins, and agrees much
better than Old Gien with the _oppidum_ of the Carnutes. Without
attaching too great faith to traditions and etymologies, we must,
nevertheless, mention a gate at Gien, which, from time immemorial, has
been called Cæsar’s Gate (_la Porte de César_); a street called _à la
Genabye_, which leads, not towards Orleans, but towards the high part of
town; a piece of ground, situated to the north of Gien, at the angle
formed by the road to Montargis and the Roman road, at a distance of
about one kilomètre, which still preserves the name of the Field of the
Camp (_La Pièce du Camp_). Perhaps this is the spot where Cæsar placed
his camp, opposite the most accessible part of the town.
The principal reason why Orleans has been taken for Genabum is that the
Itinerary of Antoninus indicates that town under the name of _Cenabum_
or _Cenabo_, and that this name is also found in some lately discovered
inscriptions. It may be supposed that the inhabitants of Gien, after
having escaped from the destruction of their town, descended the river,
and, on the spot where Orleans now stands, formed a new establishment,
to which they gave the name of the first city; in the same manner the
inhabitants of Bibracte removed to Autun, and those of Gergovia to
Clermont.
Independently of the above considerations, Orleans, by its position on a
declivity uniformly inclined toward the Loire, does not at all answer to
the conditions of a Gaulish _oppidum_. If we admit Orleans to be
Genabum, it becomes very difficult to assign a convenient site for the
_oppida_ of Vellaunodunum and Noviodunum.
_Vellaunodunum. _ The situation of the territory of the Boii being
admitted, as well as that of Genabum, we have to find, on the road which
Cæsar pursued from Sens to Gorgobina, the intermediate points of
Vellaunodunum and Noviodunum.
On the direct line from Sens to Gien, at the distance of 40 kilomètres
from Sens, we meet with the little town of Triguères. The hill which
overlooks it from the north agrees with the position of the ancient
_oppidum_; the remains of walls, fosses, and parapets have been found on
it. Farther, there were discovered in 1856, at 500 mètres to the
north-west of Triguères, the ruins of a large semi-elliptical theatre,
capable of containing from 5,000 to 6,000 spectators. In another
direction, the ruins of a Druidical monument have been pointed out; in
fact, everything leads to the belief that there existed at Triguères, in
the Gallo-Roman period, an important centre, which had been preceded by
a Gaulish establishment anterior to the conquest. A road paved with
stones, considered by some as a Gaulish or Celtic way, but accepted by
all archæologists as a Roman road, goes direct from Sens to Triguères,
by Courtenay, and passes along the eastern side of the _oppidum_.
Another ancient way leads similarly from Triguères to Gien. We feel no
hesitation, after what precedes, in placing Vellaunodunum at Triguères.
It will be objected that the distance from Sens to this little town (40
kilomètres) is too small to have taken the Roman army, without baggage,
three days’ march; but Cæsar does not say that he employed three days in
proceeding from _Agedincum_ to _Vellaunodunum_: he informs us merely
that, leaving all his baggage at Agedincum, he journeyed towards the
country of the Boii, and that on the second day he arrived at
Vellaunodunum. Nothing, therefore, obliges us to suppose that, before it
marched, the Roman army was concentrated or encamped at Agedincum
itself. Persons unacquainted with military art are apt to suppose that
an army lives and marches always concentrated on one point.
Cæsar, although he was effecting the concentration of his troops before
entering into campaign, did not keep them massed at the gates of Sens,
but he probably distributed them in _échelon_ in the neighbourhood of
the town, along the Yonne. When afterwards he decided on marching to the
succour of the Boii, we must suppose that the first day was employed in
concentrating the whole army at Sens itself, in leaving the baggage
there, perhaps also in crossing the Yonne, a long operation for more
than 60,000 men. The first day having passed, the army continued its
march next day, and arrived at Triguères the day following, having
performed two days’ march of 20 kilomètres each. We see, then, that the
distance between Sens and Triguères does not prevent us from identifying
this latter locality with Vellaunodunum. Triguères is distant 44
kilomètres from Gien, the distance which separated Vellaunodunum from
Genabum, and which might have been marched in two days.
_Noviodunum. _ To find the site of Noviodunum, we must seek a position
which agrees best with the “Commentaries” in the triangle formed by the
three known points, Gien, Le Bec-d’Allier, and Bourges. Since, according
to the text, Vercingetorix did not raise the siege of the town of the
Boii until he had heard of Cæsar’s arrival on the left bank of the
Loire, and since the two hostile armies, marching towards each other,
met at Noviodunum, it follows that this last-named town must be about
half-way between the spot where the Loire was passed and the town of the
Boii; on another hand, since Cæsar took several days to reach Bourges
from Noviodunum, there must have been a rather considerable distance
between those two last-named towns. Moreover, in order that the
inhabitants of Noviodunum should have seen in the distance, from the top
of their walls, the cavalry of Vercingetorix, the town must necessarily
have been situated on an eminence. Lastly, the cavalry combat, fought at
a small distance from the town, proves that the ground was sufficiently
flat to permit that engagement.
It is, therefore, because certain points hitherto indicated do not
answer to the conditions required by the text, that we have not
admitted, as representing Noviodunum, the towns of Nouan-le-Fuselier,
Pierrefitte-sur-Saudre, Nohant-en-Goût, Neuvy-en-Sullias, or
Neuvy-sur-Barangeon. In fact, some of these are too far from
Bec-d’Allier, while others are too near Bourges, and most of them are
situated in a plain.
Sancerre, on the contrary, answers all the conditions of the text. It is
situated on a hill which rises 115 mètres above the valley watered by
the Loire. Encircled on all sides by deep ravines, it can only be
approached from one point, situated to the east, where the ancient Roman
road of Bourges terminated, which is still at the present day called the
Big Road (_le Gros Chemin_). The Abbé Lebœuf, as early as 1727, had
designated this town as the ancient Noviodunum. It is near Saint-Satur,
at the very foot of the mountain of Sancerre, that a Gallo-Roman town
existed, of which, within the last few years, numerous foundations have
been found. It is probable that this Gallo-Roman town had succeeded to a
great centre of Gaulish population, for the Bituriges must necessarily
have occupied in their territory a point so admirably fortified by
nature, and which commanded the course of the Loire, the line of
boundary between them and the Ædui. The present town seems to have kept
within the very limits of the ancient _oppidum_; it has the form of an
ellipse of from 700 to 800 mètres in length on a breadth of about 500
mètres, capable of containing a population of from 4,000 to 5,000
inhabitants. At Sancerre there was also, at the extremity of one of the
streets, towards the north, a gate called the Gate of Cæsar (_Porte de
César_), which was demolished in the beginning of the nineteenth
century. By adopting Sancerre, all the movements of the commencement of
the campaign of 702 are easily explained. This town is forty-six
kilomètres from Gien, forty-eight kilomètres from Le Bec-d’Allier,
distances nearly equal, so that Vercingetorix and Cæsar, starting almost
at the same time from two opposite points, may have met under its walls.
Its elevated position allowed the eye to range far towards the south
along the valley of the Loire, through which the inhabitants would have
seen the approach of the cavalry of Vercingetorix. Cæsar may have
occupied with his army the heights of Verdigny or Saint-Satur, to the
north of Sancerre. A cavalry engagement may have taken place in the
valley of Saint-Satur, or on the plain between Ménétréol and
Saint-Thibaud. The captain of staff Rouby has examined with the greatest
care the places just mentioned.
Cæsar, after the surrender of Noviodunum, marches towards Bourges.
Vercingetorix follows him by short marches (_minoribus itineribus_). The
Roman general, having Bourges before him, and a hostile army on his
left, marches slowly and with precaution. Perhaps he took three or four
days to perform the forty-five kilomètres which separate Sancerre from
Bourges. At last, after having reconnoitred the site of Avaricum, he
must have traversed the marshes of the Yèvre, at a distance of three or
four kilomètres from that town, so as to take up a position to the
south-east of the _oppidum_, in that part which was not surrounded by
the river and the marshes, and which only offered a narrow passage. As
to Vercingetorix, he follows, or rather hovers on, the Roman army,
taking up his position on its left, and still keeping up his
communication with Avaricum, hesitating whether he shall deliver it to
the flames.
[469] _De Bello Gallico_, VII. 13.
[470] Archælogists have pretended they find traces still existing of the
camp of Vercingetorix in the neighbourhood of Bourges, not considering
that Cæsar declares that the Gaulish chief did not, for the first time,
think of retrenching his camp in the Roman fashion till after the siege
of this town. We believe that Vercingetorix, although he came from the
east, encamped to the south of Bourges. It was, indeed, natural that he
should place himself between the Roman army and the land of the Arverni,
whence, probably, it drew its provisions. Besides, if he had placed his
camp to the east of Bourges, he would have intercepted the provisions
which Cæsar expected from the land of the Ædui, which the text does not
say.
[471] The ravine which descends to the Auron is still recognised at the
present day, between the Portes Saint-Michel and Saint-Paul, by the
sudden incline of the ground. Old plans of Bourges designate it by the
name of the _Vallée Saint-Paul_. The opposite ravine, which runs towards
the Porte Bourbonnoux, has disappeared under the successive fillings up
composing the soil of the garden of the archbishop’s palace. The ridge
of land forming the avenue cannot have been in Cæsar’s time more than
100 mètres broad. It has lost its primitive physiognomy, especially by
the formation of the Place Sérancourt, in 1700, on a site the level of
which did not then exceed that of the field of the present fair. The
depression of the ground which existed before the wall is more visible;
it has been filled-up during the different sieges of Bourges.
[472] This is evident, since the Romans, in order to be able to give the
assault, were obliged to construct a terrace eighty feet high. General
de Gœler believed this measurement exaggerated. Nevertheless, as this
terrace was constructed in a ravine, it was necessary that it should
compensate a difference of level of eighty mètres, of which thirty,
perhaps, represent the height of the wall.
[473] Vercingetorix, encamped first towards Dun-le-Roi, had approached
nearer Bourges. He had established his new camp to the east of that of
Cæsar, perhaps at La Chenevière, at the confluence of the Yèvre and the
brook of Villabon, fourteen kilomètres from Bourges.
[474] See the quotation from Vegetius, p. 143, note (1).
[475] We read in Vitruvius, on occasion of the siege of Marseilles:
“When the tortoise approached to batter the wall, they let down a cord
furnished with a slip-knot, in which they caught the ram, and raised its
head so high, by means of a wheel, that they prevented its striking the
wall. ” (Vitruvius, X. 16. )
[476] Titus Livius expresses himself thus in speaking of the beseiged in
Ambracia, who dug a mine to meet that of the enemies: “Aperiunt viam
rectam in cuniculum. ” (XXXVII. 7. )
[477] Several authors have thought that these beams, instead of being
placed perpendicularly to the direction of the wall, were placed
parallel to that direction. This interpretation appears to us
inadmissable. The beams so placed would have no solidity, and would
easily have been torn down. We see on the Trajan Column walls
constructed as we describe; moreover, the Latin expression _trabes
directæ_ can leave no doubt, for the word _directus_ means always
_perpendicular to a direction_. (See _De Bello Gallico_, IV. 17,
_directa materia injecta_, and the dissertation in the _Philologus_,
Jahrganges 19, Heft. 3. )
[478] The name of _pluteus_ was given generally to all kinds of covering
with hurdles or with skins. (Festus, in voce _Pluteus_. --Vitruvius, X.
20. )--Vegetius (IV. 15) applies the name of _pluteus_ to a kind of
penthouse, of wicker-work or skins, mounted on three wheels, and
protecting the men placed behind it, so that they might shoot at the
defenders.
[479] They gave this name to a small engine resembling the balistæ,
which threw darts. These scorpions composed, as it were, the
field-artillery of the ancients.
[480] _De Bello Gallico_, VII. 32.
[481] It is very probably that Cæsar proceeded first to Noviodunum
(_Nevers_), since he informs us that he had established in that town a
great magazine and provisions of every kind.
[482] At present the Allier is fordable almost everywhere in summer; but
in the course of nineteen centuries the bed of the river must have been
considerably raised.
[483] The commentators are not agreed on this passage. I have adopted
the version which seemed to me the best, and which MM. Köchly and Rustow
have followed in their German translation, Stuttgart, 1862.
[484] Dio Cassius, XL. 35.
[485] Cæsar, on leaving Decize, followed, no doubt the Gaulish road
which led to the Allier, and the existence of which may be assumed from
the later construction of the Roman road which goes from Decize to
Bourbon-l’Archambault (_Aquæ Borvonis_), and which crossed the Allier a
little below Moulins. Thence he followed the course of the river for
some days, constantly in face of the enemy. In order to pass it by the
help of a stratagem, he took advantage of the remains of a bridge; and,
as this bridge indicates that there must have been a road, it becomes a
question to find among the ancient roads which crossed the Allier that
which Cæsar followed. Now we only know two Roman roads leading to the
Allier below Moulins, one at Varennes, the other at Vichy. We adopt
Varennes. That locality is seventy-seven kilomètres from Gergovia,
reckoning them along the Allier, and Cæsar took five days to perform
them; but, as the four legions sent forward to deceive the enemy
returned during the night, in order to rejoin him, they must have
suffered great fatigues; hence it is to be presumed that the next day
the first march was very short. The fifth also was not long, for,
according to the “Commentaries,” Cæsar had time on the day of his
arrival to fortify his camp, to reconnoitre the place, and to engage in
a cavalry combat. Besides, the country, interspersed with woods and
marshes, was unknown to him; and we believe that we do not depart from
the truth if we admit that the first and the last march were of no more
than ten kilomètres, and the three others of nineteen, which gives a
total of seventy-seven kilomètres, the distance from Varennes to
Gergovia. When Cæsar left Gergovia, he crossed the Allier again, but at
a point nearer to Gergovia, being in haste to place the river between
him and the enemy. Indeed, on the second day after his check, he fought
a successful cavalry engagement, broke up his camp, and the following
day (_tertio die_) crossed the Allier again, according to our opinion,
at Vichy, which is only fifty-five kilomètres from Gergovia.
[486] The Artières receives, on the north of Gergovia, the little brook
of Clémensat, marked on _Plate 21_.
[487] It is by seeking the essential conditions required for the placing
of troops that Commandant Baron Stoffel succeeded in finding the camps.
Cæsar had to place from 30,000 to 40,000 men in the neighbourhood of
water, at a convenient distance from Gergovia, and in such a manner as
to preserve his line of operation upon Nevers, where his magazines were.
These necessities indicated that the principal camp would be near the
Auzon, and to the east. Moreover, it must be sufficiently near the
_oppidum_, that from the top of the mountain of Gergovia could be seen
what was going on in it; and yet sufficiently distant that the objects
could not be clearly distinguished. The camp must be in the plain; Dio
Cassius (XL. 36) formally says, “Cæsar remained in the plain, not having
been able to take (for placing his camp) a place strong by its
elevation;” and then the “Commentaries” inform us that the Romans only
occupied one single hill, namely, the one they took by surprise (La
Roche-Blanche). Lastly, it was indispensable that there should be in
front of the camp a space sufficiently large to admit of cavalry
engagements.
[488] Vercingetorix, placed in the centre of a kind of semicircle, might
easily be considered by Cæsar as surrounded by his numerous troops
(_collocaverat copias circum se_).
[489] The combats of cavalry took place in the plain which extends from
the small eminence called _Le Puy-de-Marmant_ to the marsh of Sarlièves.
[490] The hill is certainly the Roche-Blanche, for it is situated
opposite the _oppidum_ (_e regione oppidi_); it begins at the very foot
of the slopes of the mountain of Gergovia (_sub ipsis radicibus
montis_), is singularly fortified by nature, and, as it were, cut out
from all sides (_egregie munitus atque ex omni parte circumcisus_). So
long as the Gauls occupied it, they could go to the Auzon by the ravine
of Merdogne, to obtain water and forage; but as soon as it was in the
power of the Romans, the Gauls were compelled to draw their water from
the springs on the mountain of Gergovia, and from the little brook of
Artières.
The excavations made in 1862 brought the two camps to light. The fosses
of the little camp are clearly defined in the calcareous soil. They form
an irregular outline, represented on _Plate 22_. The Roche-Blanche,
which presents in its southern part an escarpment almost as
perpendicular as a wall, has lost on the sides its abrupt form by
successive landslips, the last of which took place within memory of the
inhabitants. The communication between the great and little camps was
composed of a parapet, formed by the earth thrown out of two contiguous
fosses, each four feet in depth and six in breadth, so that the breadth
of the two together is only twelve feet. If we wonder that the Romans
should have dug two little ditches, each six feet broad and four feet
deep, instead of making one eight feet wide by six feet deep, which
would have given the same amount of soil to take out, it may be answered
that the two little ditches were much more quickly made than one large
ditch.

the summit of the Roche-Blanche. He could see neither the plateau, nor
the country situated on the norther slopes of the mountains of Gergovia
and Rissoles. It was for this reason that he had to learn from the
deserters the form of the ground which lay on the other side. He thus
learnt that the ridge of this latter mountain (_dorsum ejus jugi_) was
not very uneven, and gave access to the western part of the town (_ad
alteram partem oppidi_) by a narrow wooded passage (the defile of the
Goules, which separates Rissoles from Gergovia). (_See Plate 21 in C. _)
This defile leads to the gate _P_ of the _oppidum_.
