On his part, Cæsar resolved, with the six other legions and the rest of
the cavalry, to invade the country of the Arverni themselves, the focus
of the insurrection. He started from Decetia, and directed his march
upon Gergovia, the principal _oppidum_ of that people.

After the capture of Avaricum, Vercingetorix, suspecting Cæsar’s
ulterior designs, had moved towards the Allier, which the Romans were
obliged to pass in order to reach Gergovia; and, on the news of their
march, he had caused all the bridges to be destroyed.

Cæsar, having arrived on the banks of the Allier, towards Moulins (_see
Plate 19_), followed its downward course, on the right bank.
Vercingetorix, on his part, marched along the opposite bank. The two
armies were within sight of each other, the camps nearly opposite, and
the Gaulish scouts, who watched the left bank, prevented the Romans from
establishing a bridge. The position of the latter was difficult, for the
Allier, which is fordable in the autumn only, might delay their passage
a long time. [482] In order to surmount this obstacle, Cæsar had recourse
to a stratagem: he fixed his camp in a place covered with wood, opposite
the remains of one of the bridges which Vercingetorix had caused to be
destroyed (probably at Varennes). There he remained hidden the following
day with two legions, and made the rest of the troops, as well as the
baggage, proceed in the usual order. But, that they might present to the
enemy the appearance of six legions, he had divided into six corps the
forty cohorts or four legions which he sent forward. [483] They received
the order to march as long as possible, in order to attract
Vercingetorix, and, at the time Cæsar presumed that they had arrived at
their camp, he caused the bridge to be rebuilt on the old piles, the
lower part of which remained untouched. The work being soon completed,
the legions which remained with him passed the river, and, after having
chosen a favourable position, he recalled the mass of his army, which
rejoined him during the night. [484] When Vercingetorix was informed of
this manœuvre, fearing lest he should be compelled to fight against
his will, he took the start and marched in great haste to occupy the
_oppidum_ of the Arverni.

From the place he occupied, which we believe to have been Varennes,[485]
Cæsar reached Gergovia in five days; on the very day of his arrival,
after a slight skirmish of cavalry, he reconnoitred the position of the
town. As it was built on a very high mountain of difficult access, he
considered it impossible to take it by assault; he therefore resolved to
blockade it, and not to begin investing it until he had assured his
provisions. (_See Plate 21. _)


[Sidenote: Blockade of Gergovia. ]

VI. The _oppidum_ of the Arverni was situated at a distance of six
kilomètres to the south of Clermont-Ferrand, on the mountain which has
preserved the name of Gergovia. Its summit, elevated about 740 mètres
above the level of the sea, and 380 above the plain, forms a plateau of
1,500 mètres in length by more than 500 mètres in breadth. The northern
and eastern slopes present such abrupt declivities that they defy the
escalade. The southern slope presents a very different character: it may
be compared to an immense staircase, the steps of which would be vast
terraces with very little inclination, and a breadth which in some
places extends to as much as 150 mètres.

On the western side, the mountain of Gergovia is attached by a narrow
defile of 120 mètres in width, called the _Goules_ (_see Plate 21, C_),
to the heights of Risolles, an irregular mass, the plateau of which is
at a mean depth of about 30 mètres beneath that of Gergovia. To the west
are the detached mountains of Montrognon and Le Puy-Giroux. This latter
is separated from that of Risolles by a rather deep gorge, in which the
village of Opme is built. Opposite the southern slope of Gergovia, at
the very foot of the mountain, rises a very steep hill, called the Roche
Blanche. Its culminating point is at about 108 mètres below the plateau.
Two brooks, the Auzon and the Artières,[486] tributaries of the Allier,
flow, one to the south, the other to the north of Gergovia. Lastly, a
low tract of ground, situated to the east, indicates the site of the
ancient marsh of Sarlièves, which has been dry since the seventeenth
century.

Cæsar established his camp near the Auzon, on the undulations of the
ground which extend to the north-west of the village of Orcet, and as
far as the ancient marsh of Sarlièves. These undulations form a natural
_glacis_ towards the plain, above which they rise about thirty mètres;
on the side of the stream of the Auzon they terminate in almost
imperceptible slopes. The camp occupied a part of the table-land and of
the northern slope. [487] (_See Plate 21. _)

Vercingetorix had arranged the contingents of each country separately,
at small intervals, on the southern slopes of the mountain of Gergovia
and the mountain mass of Risolles which look towards the Auzun; they
covered all the heights attached to the principal mountain, and
presented, in the space which the eye could embrace, a formidable
aspect. [488] His principal camps were situated between the outer wall of
the _oppidum_ and a wall of large stones, six feet high, which ran along
the bend of the hill.

Every day, at sunrise, the chiefs who composed the council of
Vercingetorix repaired to him in order to make their reports or to
receive his orders. Every day, also, he tried in slight engagements[489]
the courage of his cavalry mixed with archers. The Gauls occupied, as an
advanced post, but by a weak garrison, La Roche-Blanche, which, scarped
on three sides, presented an extremely strong position; Cæsar judged
that, by taking possession of this hill, he would deprive the Gauls
almost entirely of forage and water, for they could no longer descend to
the Auzon, the only considerable stream in the neighbourhood. He started
from the camp in the silence of the night, drove away this post before
it could be succoured from the town, took the position, and placed two
legions upon it. The Roche-Blanche became his smaller camp;[490] it was
joined to the larger one by a double ditch of twelve feet, which
allowed the troops to communicate in safety, even singly, without fear
of being surprised by the enemy. (_See Plate 22. _)

During this time, the Æduan Convictolitavis, who, as we have seen, owed
the supreme magistracy to Cæsar, seduced by the money of the Arverni,
resolved to abandon the party of the Romans, and entered into
communication with several young men, at whose head was Litavicus and
his brothers, descended from an illustrious family. He shares with them
the price of his treason; exhorts them to remember that, born free, they
are made to command in their country; proves to them that the
lukewarmness of the Ædui alone delayed the general insurrection; and
that they ought to value above everything the independence of their
country. Seduced by such discourses and by the bait of gold, those young
men occupy themselves only with the means of executing their project;
yet, mistrusting the inclination of the people to be drawn into war,
they decide that Litavicus shall take the command of the 10,000 men who
were to join the Roman army, and induce them to revolt on the road,
whilst his brothers go before them to Cæsar.

Litavicus began his march. At thirty miles from Gergovia (probably at
Serbannes), he halts his troops, assembles them, and, spreading the
report that Cæsar has caused the Æduan nobility and knights who were in
his pay to be massacred, among others Eporedorix and Viridomarus, he
easily persuades them to go and join the Arverni at Gergovia, instead of
proceeding to the Roman camp. But, before taking this determination, he
gives up to plunder the convoy of provisions which marched under his
guard, causes the Romans who conducted it to be put to death with
tortures, and then sends messengers to raise the whole country of the
Ædui, by means of the same imposture. Eporedorix and Viridomarus, whose
death he had falsely announced, were with Cæsar, who, by special favour,
had raised Viridomarus from a very low to a high dignity. The former,
informed of the design of Litavicus, came in the middle of the night to
acquaint the proconsul with it, imploring him not to allow the folly of
a few young men to detach his country from the Roman alliance. It would
be too late when so many thousands of men had embraced the contrary
party.

Cæsar, more affected by this news as he had always favoured the Ædui,
takes immediately four legions, without baggage, and all the cavalry; he
waits not even to contract the compass of the two camps, for everything
depends upon celerity. His lieutenant, C. Fabius, is left to guard them,
with two legions. He orders the brothers of Litavicus to be placed under
arrest, and learns that they have just passed over to the enemy. His
soldiers, encouraged to support the fatigues of the march, follow him
with ardour, and at about twenty-five miles from Gergovia (near Randan,
on the road which Litavicus had to follow to join Vercingetorix) they
meet the Ædui. The cavalry, sent in advance, have orders to stop them
without using their arms. Eporedorix and Viridomarus, who had been
reported as dead, step forth from the ranks, speak to their
fellow-citizens, and are recognised. As soon as the deception practised
by Litavicus is discovered, the Ædui throw down their arms, ask for
pardon, and obtain it. Litavicus flies to Gergovia, with his clients,
who, in Gaul, never abandoned their patrons, not even in their worst
fortunes.

Cæsar sent to the Ædui to represent to them how generously he had acted
towards men whom the laws of war authorised him to put to death; and,
after having given his army three hours’ rest during the night, he
returned to his quarters before Gergovia. Half-way, horsemen came to
inform him of the perilous position of Fabius. The camps had been
attacked by troops which were unceasingly renewed. The Romans were
exhausted by unceasing labour, for the great extent of the enclosure
obliged them to remain continually on the _vallum_. The arrows and
missiles of all sorts thrown by the barbarians had wounded a great
number; but, on the other hand, the machines had been of great help in
supporting the defence. After the retreat of the enemies, Fabius,
expecting to be again attacked next day, had hastened to block up the
gates of the great camp, with the exception of two, and to add a
palisade to the _vallum_. On receiving this information, Cæsar hurried
his march, and, seconded by the ardour of his soldiers, arrived at the
camp before sunrise (having thus performed fifty miles, or seventy-four
kilomètres, in twenty-four hours). [491]

While these events were taking place at Gergovia, the Ædui, also
deceived by the news which Litavicus had spread, fall upon the Roman
citizens, plunder their goods, kill some, and drag others to prison. It
is Convictolitavis, also, who prompts these violences. The military
tribune M. Aristius, who was on his way to join his legion, as well as
the foreign merchants who resided in the country, are compelled to leave
Cabillonum (_Châlon-sur-Sâone_). An escort is promised to protect them;
but they have hardly started when they are attacked and stripped. They
defend themselves, and their resistance, which lasts during twenty-four
hours, calls a greater multitude to arms. However, as soon as the Ædui
hear of the new submission of their troops, they exert themselves to the
utmost to obtain their pardon; they have recourse to Aristius, throw the
blame of the outbreak upon a few, order the plundered goods to be
collected, and confiscate those of Litavicus and his brothers. They send
deputies to Cæsar to excuse themselves. Their object, in acting thus,
was to obtain the free disposal of their troops, for the consciousness
of their treason and the fear of punishment made them, at the same time,
conspire in secret with the neighbouring states.

Although informed of these secret plots, Cæsar received their deputies
with kindness, declaring that he did not hold the nation responsible for
the fault of some individuals, and that his feelings towards the Ædui
were not changed. Nevertheless, as he foresaw a general insurrection of
Gaul, which would surround him on all sides, he entertained serious
thoughts of abandoning Gergovia, and again effecting the concentration
of his whole army; but it was of importance that his retreat, caused by
the sole fear of a general defection, should not appear to be a flight.

In the midst of these cares, the besieged offered him a favourable
chance, of which he sought to take advantage. As he was visiting the
little camp to inspect the works, he perceived that a hill (no doubt the
hill marked _A_, which forms part of the mountain mass of Rissoles, _see
Plate 21_), which was almost hidden from sight by the masses of enemies
on the previous days, was clear of troops. Astonished at this change, he
inquired the cause of the deserters, who came every day in crowds to
surrender to him. All agreed in saying, as his scouts had already
reported to him, that the mountain ridge to which this hill belonged
(the top of the heights of Risolles) was almost flat, was connected with
the town, and gave access to it by a narrow and wooded defile. (_See
Plates 21 and 22. _) This point caused particular anxiety to the enemy;
for if the Romans, already masters of La Roche-Blanche, gained
possession of the mountain mass of Risolles, the Gauls would be almost
entirely invested, and could neither escape nor go to forage. This was
the reason why Vercingetorix had decided upon fortifying these heights,
and had called thither all his troops. [492]

In accordance with this information, Cæsar sends in this direction,
towards the middle of the night, several detachments of cavalry, with
orders to scour with great noise the country in every direction at the
foot of the heights of Risolles. At break of day, he sends out of the
great camp many horses and mules without pack-saddles, and causes the
muleteers to mount them, who put on helmets, so as to assume the
appearance of mounted troopers. He enjoins them to wind round the hills,
and a few cavalry who are joined with them have orders to spread wide
over the country, so as to increase the illusion. Finally, they are all,
by a long circuit, to move towards the spots which have just been
mentioned. These movements were perceived from the town, which
overlooked the camp, but at too great a distance to distinguish objects
accurately. Cæsar sends towards the same mountain mass one legion, who,
after having marched for a short distance, halt in a hollow, and pretend
to hide in the woods (towards Chanonat), so as to feign a surprise. The
suspicions of the Gauls increase; they take all their forces to the spot
threatened. Cæsar, seeing the enemy’s camp deserted, orders the military
ensigns (plumes, shields, &c. ) to be covered, the standards to be
lowered, and the troops to pass in small detachments from the great to
the little camp, behind the epaulment of the double fosse of
communication, so that they cannot be perceived from the _oppidum_. [493]
He communicates his intentions to the lieutenants placed at the heads of
the legions, recommends them to take care to prevent the soldiers from
allowing themselves to be carried away by the ardour of the combat or
the hope of plunder, and draws their attention to the difficulties of
the ground. “Celerity alone,” he says, “can enable us to overcome them;
in fact, it is to be an attack by surprise, and not a fight. ” Having
communicated these directions, he gives the signal, and, at the same
time, sends the Ædui out of the great camp, with orders to climb the
eastern slopes of the mountain of Gergovia, to effect a diversion to the
right. (_See Plate 21. _)

The distance from the wall of the _oppidum_ to the foot of the mountain,
where the ground is almost flat, was 1,200 paces (1,780 mètres) in the
most direct line; but the way was longer, on account of the circuits it
was necessary to make to break the steepness. [494] Towards the middle of
the southern slope, in the direction of its length, the Gauls, taking
advantage of the character of the ground, had, as we have said, built a
wall of large stones, six feet high, a serious obstacle in case of
attack. The lower part of the slopes had remained free; but the upper
part, up to the wall of the _oppidum_, was occupied with camps placed
very near together. When the signal is given, the Romans reach rapidly
the wall, scale it, and take three camps with such promptitude, that
Teutomatus, king of the Nitiobriges, surprised in his tent where he was
taking his repose in the middle of the day, fled half naked; his horse
was wounded, and he escaped with difficulty from the hands of the
assailants.

Cæsar, satisfied with this success, ordered the retreat to be sounded,
and made the tenth legion, which accompanied him, halt (from an
examination of the ground, the spot where Cæsar stood is the knoll which
rises to the west of the village of Merdogne). (_See Plate 21_, first
position of the tenth legion. ) But the soldiers of the other legions,
separated from him by a rather wide ravine, did not hear the trumpet.
Although the tribunes and the lieutenants did all they could to restrain
them, excited by the hope of an easy victory, and by the recollection of
their past successes, they thought nothing was insurmountable to their
courage, and persisted in the pursuit of the enemy up to the walls and
gates of the _oppidum_.

Then an immense cry arises in the town. The inhabitants of the most
remote quarters believe that it is invaded, and rush out of the walls.
The matrons throw from the top of the walls their precious objects to
the Romans, and, with breasts bare and hands extended in supplication,
implore them not to massacre the women and children, as at Avaricum.
Several even, letting themselves down from the walls, surrender to the
soldiers. L. Fabius, centurion of the 8th legion, excited by the rewards
given at Avaricum, had sworn to be the first to mount to the assault; he
is lifted up by three soldiers of his company, reaches the top of the
wall, and, in his turn, helps them to mount one after the other.

Meanwhile the Gauls, who, as we have seen, had proceeded to the west of
Gergovia to raise retrenchments, hear the cries from the town; repeated
messages announce the capture of the _oppidum_. They immediately hurry
towards it, sending their cavalry before them. As they arrive, each man
takes his stand under the wall and joins the combatants, and their
number increases every moment; while the same women who just before
implored the pity of the besiegers, now excite against them the
defenders of Gergovia, displaying their dishevelled hair and showing
their children. The place as well as the numbers rendered the struggle
unequal; the Romans, fatigued with their run and the length of the
combat, resisted with difficulty troops which were still fresh.

This critical state of things inspired Cæsar with alarm; he ordered T.
Sextius, who had been left to guard the little camp, to bring out the
cohorts quickly, and take a position at the foot of the mountain of
Gergovia, on the right of the Gauls, so as to support the Romans if they
were repulsed, and check the enemy’s pursuit. He himself, drawing the
10th legion a little back[495] from the place where he had posted it,
awaited the issue of the engagement. (_See Plate 21_, second position of
the 10th legion. )

When the struggle was most obstinate, suddenly the Ædui, who had been
sent to divert the attention of the enemy by an attack from another
side, appeared on the right flank of the Romans. The resemblance of
their arms to those of the Gauls caused a great alarm; and although they
had their right shoulders bare (_dextris humeris exsertis_), the
ordinary mark of the allied troops, it was taken for a stratagem of the
enemy. At the same moment, the centurion L. Fabius, and those who had
followed him, are surrounded and thrown down from the top of the wall.
M. Petronius, centurion of the same legion, overwhelmed by numbers in
his attempt to burst the gates, sacrifices himself for the safety of his
soldiers, and meets his death in order to give them time to join their
ensigns. Pressed on all sides, the Romans are driven back from the
heights, after having lost forty-six centurions; nevertheless, the 10th
legion, placed in reserve on more level ground (_see Plate 21_, third
position), arrests the enemies, who are too eager in their pursuit. It
is supported by the cohorts of the 13th, who had just taken position on
a commanding post (_Le Puy-de-Marmant_), under the command of the
lieutenant T. Sextius. As soon as the Romans had reached the plain, they
rallied, and formed front against the enemy. But Vercingetorix, once
arrived at the foot of the mountain, ventured no further, but led back
his troops within the retrenchments. This day cost Cæsar nearly 700
men. [496]

Next day, Cæsar assembled his troops, and reprimanded them for their
rashness and for their thirst for plunder. He reproached them with
having “wished to judge for themselves of the object to be attained, and
of the means of attack, and not listening either to the signal of
retreat or to the exhortations of the tribunes and lieutenants. He
pointed out to them all the importance of the difficulties caused by the
inequalities of the ground; and reminded them of his conduct at
Avaricum, where, in presence of an enemy without chief and without
cavalry, he had renounced a certain victory rather than expose himself
to loss, though slight, in a disadvantageous position. Much as he
admired their bravery, which had been checked neither by the
retrenchments, nor by the steepness of the ground, nor by the walls, he
blamed no less their disobedience and their presumption in believing
themselves capable of judging of the chances of success and calculating
the issue of the undertaking better than their general. He demanded of
the soldiers submission and discipline, no less than firmness and
bravery; and, to revive their courage, he added that their want of
success was to be attributed to the difficulties of the ground much more
than to the valour of the enemy. ”[497]


[Sidenote: Observations. ]

VII. In the foregoing account, which is taken almost literally from the
“Commentaries,” Cæsar skilfully disguises a defeat. It is evident that
he hoped to take Gergovia by a sudden assault, before the Gauls, drawn
by a false attack to the west of the town, had time to come back to its
defence. Deceived in his expectation, he ordered the retreat to be
sounded, but too late to be executed in good order. Cæsar does not
appear to be sincere when he declares that he had attained his object
the moment his soldiers reached the foot of the wall. This could not
have been the case, for what use could it be to him to take camps almost
without troops in them, if the consequence was not to be the surrender
of the town itself? The defeat appears to have been complete, and,
according to some, Cæsar was for a moment a prisoner in the hands of the
Gauls; according to others, he had only lost his sword. Servius, indeed,
relates the following rather incomprehensible anecdote: when Cæsar was
taken away prisoner by the Gauls, one of them began to cry out _Cæsar_,
which signifies in Gaulish _let him go_, and thus he escaped. [498]
Plutarch gives another version: “The Arverni,” he says, “still show a
sword hung up in one of their temples, which they pretend to be a spoil
taken from Cæsar. He saw it there himself subsequently, and only laughed
at it. His friends engaged him to take it away, but he refused,
pretending that it had become a sacred object. ”[499] This tradition
proves that he was sufficiently great to bear the recollection of a
defeat, in which he was very different from Cicero, whom we have seen
stealthily taking away from the Capitol the brass plate on which was
engraved the law of his banishment.


[Sidenote: Cæsar leaves Gergovia in order to join Labienus. ]

VIII. Cæsar, after the check he had suffered before Gergovia, persisted
all the more in his intentions of departure; but, not to have the
appearance of flight, he drew out his legions, and placed them in order
of battle on an advantageous ground. Vercingetorix did not allow himself
to be drawn into the plain; the cavalry only fought, and the combat was
favourable to the Romans, who afterwards returned to their camp. The
next day the same manœvre was repeated with the same success.
Thinking that he had done enough to abate the boasting of the Gauls, as
well as to strengthen the courage of his men, Cæsar left Gergovia, and
took his way towards the country of the Ædui.

His withdrawal did not draw out the enemies in pursuit; and he arrived
on the third day (that is, his second day’s march, reckoning from the
assault on Gergovia) on the banks of the Allier, rebuilt one of the
bridges, no doubt that of Vichy, and crossed the river in haste, in
order to place it between him and Vercingetorix.

There Viridomarus and Eporedorix urged upon him the necessity of their
presence among the Ædui, in order to maintain the country in obedience,
and to be beforehand with Litavicus, who had gone thither with all the
cavalry to excite a revolt. Notwithstanding the numerous proofs of their
perfidy, and the suspicion that the departure of those two chiefs would
hasten the revolt, he did not think proper to detain them, as he wished
to avoid even the appearance of violence or of fear. He confined himself
to reminding them of the services which he had rendered to their
country, and of the state of dependence and abasement from which he had
drawn them, to raise them to a high degree of power and prosperity, and
then dismissed them; and they proceeded to Noviodunum (_Nevers_). This
town of the Ædui was situated on the banks of the Loire, in a favourable
position. It contained all the hostages of Gaul, the stores, the public
treasury, nearly all the baggage of the general and the army, and,
lastly, a considerable number of horses bought in Italy and Spain.
Eporedorix and Viridomarus heard there, on their arrival, of the revolt
of the country, of the reception of Litavicus in the important town of
Bibracte by Convictolitavis and a great part of the Senate, as well as
of the steps taken to draw their fellow-citizens into the cause of
Vercingetorix. The occasion appears favourable to them: they massacre
the guards of the dépôt of Noviodunum and the Roman merchants, share
amongst themselves the horses and the money, burn the town, send the
hostages to Bibracte, load boats with all the grain they can take away,
and destroy the rest by water and fire; then they collect troops in the
neighbourhood, place posts along the Loire, spread their cavalry
everywhere in order to intimidate the Romans, to cut off their supply of
provisions, and to compel them through famine to retire into the
Narbonnese--a hope which was so much the better founded, as the Loire,
swollen by the melting of the snow, appeared to be nowhere fordable.

Cæsar was informed of these events during his march from the Allier
towards the Loire. His position had never been more critical. Suffering
under a severe defeat, separated from Labienus by a distance of more
than eighty leagues, and by countries in revolt, he was surrounded on
all sides by the insurrection: he had on his rear the Arverni, elated
with their recent success at Gergovia; on his left the Bituriges,
irritated by the sack of Avaricum; before him the Ædui, ready to dispute
the passage of the Loire. Was he to persevere in his design, or
retrograde towards the Province? He could not resolve on this latter
course, for not only would this retreat have been disgraceful, and the
passage of the Cévennes full of difficulties, but, above all, he felt
the greatest anxiety for Labienus and the legions which he had entrusted
to him. He therefore persevered in his first resolutions; and in order
to be able, in case of need, to build a bridge across the Loire before
the forces of the enemies were increased, he proceeded towards that
river by forced marches day and night, and arrived unexpectedly at
Bourbon-Lancy. [500] The cavalry soon discovered a ford which necessity
made them consider practicable, although the soldiers had only above
water their shoulders and their arms to carry their weapons. The cavalry
was placed up the stream, in order to break the current, and the army
passed without accident before the enemy had time to recover from his
first surprise. Cæsar found the country covered with the harvest and
with cattle, with which the army was largely provisioned, and he marched
towards the land of the Senones. [501]


[Sidenote: Expedition of Labienus against the Parisii. ]

IX. Whilst the centre of Gaul was the scene of these events, Labienus
had marched with four legions towards Lutetia, a town situated on an
island in the Seine, the _oppidum_ of the Parisii. After leaving his
baggage at Agedincum (_Sens_)[502] under the guard of the troops
recently arrived from Italy to fill up the voids, he followed the left
bank of the Yonne and of the Seine, wishing to avoid all important
streams and considerable towns. [503] At the news of his approach, the
enemy assembled in great numbers from the neighbouring countries. The
command was entrusted to Aulercus Camulogenus, who was elevated to this
honour, notwithstanding his great age, on account of his rare ability in
the art of war. This chief, having remarked that a very extensive marsh
sloped towards the Seine, and rendered impracticable all that part of
the country which is watered by the Essonne, established his troops
along the side of this marsh, in order to defend the passage. (_See
Plate 23. _)

When Labienus arrived on the opposite bank, he ordered covered galleries
to be pushed forward, and sought, by means of hurdles and earth, to
establish a road across the marsh; but, meeting with too many
difficulties, he formed the project of surprising the passage of the
Seine at Melodunum (_Melun_), and, when once on the right bank, of
advancing towards Lutetia by stealing a march upon the enemy. He
therefore left his camp in silence, at the third watch (midnight), and,
retracing his steps, arrived at Melun, an _oppidum_ of the Senones,
situated, like Lutetia, on an island in the Seine. He seized about fifty
boats, joined them together, filled them with soldiers, and entered into
the place without striking a blow. Terrified at this sudden attack, the
inhabitants, a great part of whom had answered to the appeal of
Camulogenus, offered no resistance. A few days before, they had cut the
bridge which united the island with the right bank; Labienus restored
it, led his troops over it, and proceeded towards Lutetia, where he
arrived before Camulogenus. He took a position near the place where
Saint-Germain-l’Auxerrois now stands. Camulogenus, informed by those who
had fled from Melun, quits his position on the Essonne, returns to
Lutetia, gives orders to burn it and to cut the bridges, and establishes
his camp on the left bank of the Seine, in front of the _oppidum_, that
is, on the present site of the Hotel de Cluny.

It was already rumoured that Cæsar had raised the siege of Gergovia; the
news of the defection of the Ædui, and of the progress of the
insurrection, had begun already to spread. The Gauls repeated
incessantly that Cæsar, arrested in his march by the Loire, had been
compelled, by want of provisions, to retire towards the Roman province.
The Bellovaci, whose fidelity was doubtful, had no sooner heard of the
revolt of the Ædui, than they collected troops and prepared openly for
war.

At the news of so many unfavourable events, Labienus felt all the
difficulties of his situation. Placed on the right bank of the Seine, he
was threatened on one side by the Bellovaci, who had only to cross the
Oise to fall upon him; on the other by Camulogenus, at the head of a
well-trained army, ready to give battle; lastly, a large river, which he
had crossed at Melun, separated him from Sens, where he had his dépôts
and baggage. To escape from this perilous position, he thought it
advisable to change his plans: he renounced all offensive movements, and
resolved to return to his point of departure by an act of daring.
Fearing that, if he went by the road on which he had advanced, he should
not be able to cross the Seine at Melun, because his boats would not
have re-mounted the river without difficulty, he decided on surprising
the passage of the Seine below Paris, and returning to Sens by the left
bank, marching over the body of the Gaulish army. Towards evening he
convoked a council, and urged on his officers the punctual execution of
his orders. He entrusted the boats he had brought from Melun to the
Roman knights, with orders to descend the river at the end of the first
watch (ten o’clock), to advance in silence for the space of four miles
(six kilomètres), which would bring them as far down as the village of
Point-du-Joir, and to wait for him. The five cohorts which had least
experience were left in charge of the camp, and the five others of the
same legion received orders to re-ascend on the right bank of the river
in the middle of the night, with all their baggage, and attract by their
tumult the attention of the enemy. Boats were sent in the same
direction, which were rowed with great noise. He himself, a little
after, left in silence with the three remaining legions, and, proceeding
down the river, repaired to the spot where the first boats waited for
him.

When he arrived there, a violent storm enabled him to carry by surprise
the Gaulish posts placed along the whole bank.
The legions and cavalry
had soon passed the Seine with the assistance of the knights. Day began
to appear, when the enemy learnt, almost at the same instant, first,
that an unusual agitation prevailed in the Roman camp, that a
considerable column of troops was ascending the river, and that in the
same direction a great noise of oars was heard; lastly, that lower down
the stream the troops were crossing the Seine in boats. This news made
the Gauls believe that the legions intended to cross it on three points,
and that, perplexed by the defection of the Ædui, they had decided on
forcing the road by the left bank. [504] Camulogenus divided also his
forces into three corps: he left one opposite the Roman camp; sent the
second, less numerous, in the direction of Melodunum,[505] with
instructions to regulate its march according to the progress of the
enemy’s boats which re-ascended the Seine; and, at the head of the
third, went to meet Labienus.

At sunrise the Roman troops had crossed the river, and the enemy’s army
appeared drawn up in order of battle. Labienus exhorts his soldiers to
recall to mind their ancient valour, and so many glorious exploits, and,
as they marched to the combat, to consider themselves under the eye of
Cæsar, who had led them so often to victory: he then gives the signal.
At the first shock the 7th legion, placed on the right wing, routs the
enemy; but on the left wing, although the 12th legion had transpierced
the first ranks with their _pila_, the Gauls defend themselves
obstinately, and not one dreams of flight. Camulogenus, in the midst of
them, excites their ardour. The victory was still doubtful, when the
tribunes of the 7th legion, informed of the critical position of the
left wing, lead their soldiers to the back of the enemies, and take them
in the rear. The barbarians are surrounded, yet not one yields a step;
all die fighting, and Camulogenus perishes with the rest. The Gaulish
troops left opposite the camp of Labienus had hurried forward at the
first news of the combat, and had taken possession of a hill (probably
that of Vaugirard); but they did not sustain the attack of the
victorious Romans, and were hurried along in the general rout; all who
would not find refuge in the woods and on the heights were cut to pieces
by the cavalry.

After this battle Labienus returned to Agedincum; thence he marched with
all his troops, and went to join Cæsar. [506]


[Sidenote: The Gauls assume the offensive. ]

X. The desertion of the Ædui gave the war a greater development.
Deputies are sent in all directions: credit, authority, money,
everything is put in activity to excite the other states to revolt.
Masters of the hostages whom Cæsar had entrusted to them, the Ædui
threaten to put to death those who belong to the nations which hesitate.
In a general assembly of Gaul, convoked at Bibracte, at which the Remi,
the Lingones, and the Treviri only were absent, the supreme command is
conferred on Vercingetorix, in spite of the opposition of the Ædui, who
claim it, and who, seeing themselves rejected, begin to regret the
favours they had received from Cæsar. But they had pronounced for the
war, and no longer dare to separate themselves from the common cause.
Eporedorix and Viridomarus, young men of great promise, obey
Vercingetorix unwillingly. The latter begins by exacting from the other
states hostages to be delivered on a fixed day; orders that the cavalry,
amounting to 15,000 men, shall be gathered round his person; declares he
has infantry enough at Bibracte, for his intention is not to offer a
pitched battle to the Romans, but, with a numerous cavalry, to intercept
their convoys of grain and forage. He exhorts the Gauls to set fire
with a common accord to their habitations and crops, which are only
small sacrifices in comparison to their liberty. These measures having
been decided, he demands from the Ædui and the Segusiavi, who bordered
upon the Roman province, 10,000 foot soldiers, sends them 800 horse, and
gives the command of these troops to the brother of Eporedorix, with
orders to carry the war into the country of the Allobroges. On another
side, he orders the Gabali and the neighbouring cantons of the Arverni
to march against the Helvii, and sends the Ruteni and the Cadurci to lay
waste the country of the Volcæ Arecomici. At the same time, he labours
secretly to gain the Allobroges, in the hope that the remembrance of
their ancient struggles against the Romans is not yet effaced. He
promises money to their chiefs, and to their country the sovereignty
over the whole Narbonnese.

To meet these dangers, twenty-two cohorts, raised in the province, and
commanded by the lieutenant Lucius Cæsar,[507] had to face the enemy on
every side. The Helvii, faithful to the Romans, by their own impulse,
attacked their neighbours in the open field; but repulsed with loss, and
having to deplore the death of their chiefs, among others that of C.
Valerius Donnotaurus, they ventured no more outside their walls. As to
the Allobroges, they defended their territory with energy, by placing a
great number of posts along the Rhone. The superiority of the enemy in
cavalry, the interruption of the communications, the impossibility of
drawing succour from Italy or the province, decided Cæsar on demanding
from the German peoples on the other side of the Rhine, subdued the year
before, cavalry and light infantry accustomed to fight intermingled. On
their arrival, finding that the cavalry were not sufficiently well
mounted, he distributed amongst them the horses of the tribunes, and
even those of the Roman knights and the volunteers (_evocati_). [508]


[Sidenote: Junction of Cæsar and Labienus. Battle of the Vingeanne. ]

XI. The line of march followed by Cæsar after he had crossed the Loire
has been the subject of numerous controversies. Yet the “Commentaries”
appear to us to furnish sufficient data to determine it with precision.
On leaving Gergovia, Cæsar’s object was, as he tells us himself, to
effect a junction with Labienus; with this view, he marched towards the
land of the Senones, after having crossed the Loire at Bourbon-Lancy. On
his part, Labienus, after returning to Sens, having advanced to meet
Cæsar, their junction must necessarily have taken place on a point of
the line from Bourbon-Lancy to Sens; this point, in our opinion, is
Joigny. (_See Plate 19. _) Encamped not far from the confluence of the
Armançon and the Yonne, Cæsar could easily receive the contingent which
he expected from Germany.

The Roman army was composed of eleven legions: the 1st, lent by Pompey,
and the 6th, 7th, 8th, 9th, 10th, 11th, 12th, 13th, 14th, and 15th. [509]
The effective force of each of them varied from 4,000 to 5,000 men;
for, if we see (lib. V. 49) that on the return from Britain two legions
reckoned together only 7,000 men, their effective force was soon
increased by considerable re-enforcements which came to the army of Gaul
in 702;[510] the legion lent by Pompey was of 6,000 men;[511] and the
13th, at the breaking out of the civil war, had in its ranks 5,000
soldiers. [512] Cæsar had then at his disposal, during the campaigns
which ended with the taking of Alesia, 50,000 legionaries, and perhaps
20,000 Numidian or Cretan archers, and 5,000 or 6,000 cavalry, a
thousand of whom were Germans, making a total of about 75,000 men,
without counting the valets, who were always very numerous.

When the junction of the troops had been effected, Cæsar sought above
all to approach the Roman province, in order to carry succour to it with
more ease; he could not think of taking the most direct road, which
would have led him into the country of the Ædui, one of the centres of
the insurrection; he was, therefore, obliged to pass through the
territory of the Lingones, who had remained faithful to him, and to
proceed into Sequania, where Besançon offered an important place of
arms. (_See Plate 19. _) He started from Joigny, following the road which
he had taken when he marched to meet Ariovistus (696),[513] and the
winter before, when he moved from Vienne to Sens. After reaching the
Aube at Dancevoir, he proceeded towards the little river Vingeanne,
crossing, as the “Commentaries” say, the extreme part of the territory
of the Lingones (_per extremos Lingonum fines_). [514] His intention was,
no doubt, to cross the Saône, either at Gray, or at Pontailler.

Whilst the Romans abandoned that part of Gaul which had revolted, in
order to approach nearer to the province, Vercingetorix had assembled
his army, amounting to more than 80,000 men, at Bibracte; it had come in
great part from the country of the Arverni, and counted in its ranks the
cavalry furnished by all the states. Having been informed of Cæsar’s
march, he started at the head of his troops, to bar the road through
Sequania. Passing, as we believe, by Arnay-le-Duc, Sombernon, Dijon, and
Thil-Châtel, he arrived at the heights of Occey, Sacquenay, and
Montormentier, where he formed three camps, at a distance of 10,000
paces (fifteen kilomètres) from the Roman army. (_See Plate 24. _) In
this position Vercingetorix intercepted the three roads which Cæsar
could have taken towards the Saône, either at Gray, or at Pontailler, or
at Chalon. [515] Resolved on risking a battle, he convoked the chiefs of
the cavalry. “The moment of victory,” he told them, “has arrived; the
Romans fly into their province, and abandon Gaul. If this retreat
delivers us for the present, it ensures neither peace nor rest for the
future; they will return with greater forces, and the war will be
endless. We must attack them, therefore, in the disorder of their march;
for if the legions stop to defend their long convoy, they will not be
able to continue their road; or if, which is more probable, they abandon
their baggage in order to secure their own safety, they will lose what
is indispensable to them, and, at the same time, their prestige. As to
their cavalry, they will surely not dare to move away from the column;
that of the Gauls must show so much the more ardour, as the infantry,
ranged before the camp, will be there to intimidate the enemy. ” Then,
the cavalry exclaimed, “Let every one swear, by a solemn oath, never to
return to the home of his forefathers, his wife, or his children, if he
has not ridden twice through the ranks of the enemy! ” This proposition
was received with enthusiasm, and all took the oath.

The day on which Vercingetorix arrived on the heights of Sacquenay,[516]
Cæsar, as we have seen, encamped on the Vingeanne, near Longeau.
Ignorant of the presence of the Gauls, he started next day, in marching
column, the legions at a great distance from each other, separated by
their baggage. When his vanguard arrived near Dommarien, it could
perceive the hostile army. Vercingetorix was watching the moment they
(the Romans) debouched, to attack. He had divided his cavalry in three
bodies, and his infantry had descended from the heights of Sacquenay in
order to take a position along the Vingeanne and the Badin. (_See Plate
24. _) As soon as the vanguard of the enemy appears, Vercingetorix bars
its way with one of the bodies of cavalry, while the two others show
themselves in order of battle on the two wings of the Romans. Taken
unexpectedly, Cæsar divides his cavalry also into three bodies, and
opposes them to the enemy. The combat engages on all sides; the column
of the Roman army halts; the legions are brought into line, and the
baggage placed in the intervals. This order, in which the legions were,
no doubt, in column of three deep, was easy to execute, and presented
the advantages of a square. Wherever the cavalry gives way or is too
hotly pressed, Cæsar sends to its support the cohorts, which he draws
from the main body to range them in order of battle. [517] By this
manœuvre he renders the attacks less vigorous, and increases the
confidence of the Romans, who are assured of support. Finally, the
German auxiliaries, having gained, to the right of the Roman army, the
summit of a height (the hill of Montsaugeon), drive the enemies from it,
and pursue the fugitives as far as the river, where Vercingetorix stood
with his infantry. At the sight of this rout, the rest of the Gaulish
cavalry fear to be surrounded, and take to flight. From this time the
battle became a mere carnage. Three Ædui of distinction are taken and
brought to Cæsar: Cotus, chief of the cavalry, who, at the last
election, had contended with Convictolitavis for the sovereign
magistracy; Cavarillus, who, since the defection of Litavicus, commanded
the infantry; and Eporedorix, whom the Ædui had for chief in their war
against the Sequani, before the arrival of Cæsar in Gaul. [518]


[Sidenote: Blockade of Alesia. ]

XII. Vercingetorix, after the defeat of his cavalry, decided on a
retreat; taking his infantry with him, without returning to his camp, he
marched immediately towards Alesia, the _oppidum_ of the Mandubii. The
baggage, withdrawn from the camp, followed him without delay. [519] Cæsar
ordered his baggage to be carried to a neighbouring hill, under the
guard of two legions, pursued the enemies as long as daylight permitted,
killed about 3,000 men of their rear-guard, and established his camp,
two days afterwards, before Alesia. [520] After having reconnoitred the
position of the town, and taking advantage of the disorder of the enemy,
who had placed his principal confidence in his cavalry, which was thrown
into consternation by its defeat, he resolved to invest Alesia, and
exhorted his soldiers to support the labours and fatigues of a siege
with constancy.

Alise-Sainte-Reine, in the department of the Côte-d’Or, is, undoubtedly,
the Alesia of the “Commentaries. ” The examination of the strategic
reasons which determined the march of Cæsar, the correct interpretation
of the text, and, lastly, the excavations lately made, all combine to
prove it. [521]

Ancient Alesia occupied the summit of the mountain now called Mont
Auxois; on the western slope is built the village of Alise-Sainte-Reine.
(_See Plates 25 and 26_. ) It is an entirely isolated mountain, which
rises 150 to 160 mètres above the surrounding valleys (_erat oppidum
Alesia in colle summo, admodum edito loco . . . _). Two rivers bathe the
foot of the mountain on two opposite sides: they are the Ose and the
Oserain (_cujus collis radices duo duabus ex partibus flumina
subluebant_). To the west of Mont Auxois the plain of Laumes extends,
the greatest dimension of which, between the village of Laumes and that
of Pouillenay, is 3,000 paces or 4,400 mètres (_ante oppidum planities
circiter millia passuum III in longitudinem patebat_). On all other
sides, at a distance varying from 1,100 to 1,600 mètres, rises a belt of
hills, the plateaux of which are at the same height (_reliquis ex
omnibus partibus colles, mediocri interjecto spatio, pari altitudinis
fastigio oppidum cingebant_).

The summit of Mont Auxois has the form of an ellipse, 2,100 mètres in
length, and 800 mètres broad in its greatest diameter. Including the
first spurs which surround the principal mass, it is found to contain a
superficies of 1,400,000 square mètres, 973,100 mètres of which for the
upper plateau and 400,000 mètres for the terraces and spurs. (_See Plate
25_. ) The town appears to have crowned the whole of the plateau, which
was protected by scarped rocks against all attack. [522]

This _oppidum_ could, apparently, only be reduced by a complete
investment. The Gaulish troops covered, at the foot of the wall, all the
slopes of the eastern part of the mountain; they were there protected by
a fosse and by a wall of unhewn stones six feet high. Cæsar established
his camps in favourable positions, the infantry on the heights, the
cavalry near the watercourses. These camps, and twenty-three redoubts or
blockhouses,[523] formed a line of investment of 11,000 paces (sixteen
kilomètres). [524] The redoubts were occupied in the day by small posts,
to prevent any surprise; by night, strong detachments bivouacked in
them.

The works were hardly begun, when a cavalry engagement took place in the
plain of Laumes. The combat was very hot on both sides. The Romans were
giving way, when Cæsar sent the Germans to their assistance, and ranged
the legions in order of battle in front of the camps, so that the
enemy’s infantry, kept in awe, should not come to the assistance of the
cavalry. That of the Romans recovered confidence on seeing that they
were supported by the legions. The Gauls, obliged to fly, became
embarrassed by their own numbers, and rushed to the openings left in the
wall of unhewn stones, which were too narrow for the occasion. Pursued
with fury by the Germans up to the fortifications, some were slain, and
others, abandoning their horses, attempted to cross the fosse and climb
over the wall. Cæsar then ordered the legions, who were drawn up before
his retrenchments, to advance a little. This movement carried disorder
into the Gaulish camp. The troops within feared a serious attack, and
the cry to arms rose on all sides. Some, struck with terror, threw
themselves into the _oppidum_; Vercingetorix was obliged to order the
gates to be closed, for fear the camp should be abandoned. The Germans
retired, after having killed a great number of the cavalry, and taken a
great number of horses.

Vercingetorix resolved to send away all his cavalry by night, before the
Romans had completed the investment. He urges the cavalry, on their
departure, to return each to his country, and recruit the men able to
carry arms; he reminds them of his services, and implores them to think
of his safety, and not to deliver him as a prey to the enemies, him who
has done so much for the general liberty: their indifference would
entail with his loss that of 80,000 picked men. On an exact calculation,
he has only provisions for one month; by husbanding them carefully, he
may hold out some time longer. After these recommendations, he causes
his cavalry to leave in silence, at the second watch (nine o’clock). It
is probable that they escaped by ascending the valleys of the Ose and
the Oserain. Then he orders, on pain of death, all the corn to be
brought to him. He divides among the soldiers individually the numerous
cattle which had been collected by the Mandubii; but as to the grain,
he reserves the power of distributing it gradually and in small
quantities. All the troops encamped outside withdraw into the _oppidum_.
By these dispositions he prepares to wait for the succour of Gaul, and
to sustain the war.

As soon as Cæsar was informed of these measures by the prisoners and
deserters, he resolved to form lines of countervallation and
circumvallation, and adopted the following system of fortifications: he
ordered first of all to be dug, in the plain of Laumes, a fosse twenty
feet wide, with vertical walls, that is, as wide at the bottom as at the
level of the ground (_see Plates 25 and 28_), so as to prevent lines so
extensive, and so difficult to guard with soldiers along their whole
extent, from being attacked suddenly by night, and also to protect the
workmen from the darts of the enemy during the day. Four hundred feet
behind this fosse, he formed the countervallation. He then made two
fosses of fifteen feet wide, of equal depth,[525] and filled the
interior fosse--that is, the one nearest to the town--with water derived
from the river Oserain. Behind these fosses he raised a rampart and a
palisade (_aggerem ac vallum_), having together a height of twelve feet.
Against this was placed a fence of hurdles with battlements (_loricam
pinnasque_); strong forked branches were placed horizontally at the
junction of the hurdle-fence and the rampart, so as to render them more
difficult to scale. (_See Plate 27. _) Lastly, he established towers on
all this part of the countervallation, with a distance of eighty feet
between them.

It was necessary at the same time to work at widely extended
fortifications, and to fetch in wood and provisions, so that these
distant and toilsome expeditions diminished incessantly the effective
force of the combatants; and the Gauls, too, often attempted to harass
the workmen, and even made vigorous sallies, through several gates at a
time. Cæsar judged it necessary to increase the strength of the works,
so that they might be defended with a smaller number of men. He ordered
trees or large branches to be taken, the extremities of which were
sharpened and cut to a point;[526] they were placed in a fosse five feet
deep; and, that they might not be torn up, they were tied together at
the lower part; the other part, furnished with branches, rose above
ground. There were five rows of these, contiguous and interlaced;
whoever ventured amongst them would be wounded by their sharp points;
they were called _cippi_. In front of these sorts of _abatis_ were dug
wolves’ pits (_scrobes_), trunconic fosses, of three feet deep, disposed
in the form of a quincunx. In the centre of each hole was planted a
round stake, of the thickness of a man’s thigh, hardened in the fire,
and pointed at the top; it only rose about four inches above ground. In
order to render these stakes firmer, they were surrounded at the base
with earth well stamped down; the rest of the excavation was covered
with thorns and brushwood, so as to conceal the trap. There were eight
rows of holes, three feet distant from each other: they were called
_lilies_ (_lilia_), on account of their resemblance to the flower of
that name. Lastly, in front of these defences were fixed, level with
the ground, stakes of a foot long, to which were fixed irons in the
shape of hooks. These kind of caltrops, to which they gave the name of
_stimuli_,[527] were placed everywhere, and very near each other.

When this work was finished, Cæsar ordered retrenchments to be dug,
almost similar, but on the opposite side, in order to resist attacks
from the exterior. This line of circumvallation, of fourteen miles in
circuit (twenty-one kilomètres), had been formed on the most favourable
ground, in conforming to the nature of the locality. If the Gaulish
cavalry brought back an army of succour, he sought by these means to
prevent it, however numerous it might be, from surrounding the posts
established along the circumvallation. In order to avoid the danger
which the soldiers would have run in quitting the camps, he ordered that
every man should provide himself with provisions and forage for thirty
days. Notwithstanding this precaution, the Roman army suffered from
want. [528]

Whilst Cæsar adopted these measures, the Gauls, having convoked an
assembly of their principal chiefs, probably at Bibracte, decided not to
collect all their men able to bear arms, as Vercingetorix wished, but to
demand from each people a certain contingent, for they dreaded the
difficulty of providing for so large and so confused a multitude, and of
maintaining order and discipline. The different states were required to
send contingents, the total of which was to amount to 283,000 men; but,
in reality, it did not exceed 240,000. The cavalry amounted to
8,000. [529]

The Bellovaci refused their contingent, declaring that they intended to
make war on their own account, at their own will, without submitting to
anybody’s orders. Nevertheless, at the instance of Commius, their host,
they sent 2,000 men.

This same Commius, we have seen, had in previous years rendered signal
service to Cæsar in Britain. In return for which, his land, that of the
Atrebates, freed from all tribute, had recovered its privileges, and
obtained the supremacy over the Morini. But such was then the eagerness
of the Gauls to re-conquer their liberty and their ancient glory, that
all feelings of gratitude and friendship had vanished from their memory,
and all devoted themselves body and soul to the war.

The numbering and the review of the troops took place on the territory
of the Ædui. The chiefs were named; the general command was given to the
Atrebatan Commius; to the Æduans Viridomarus and Eporedorix, and to the
Arvernan Vercasivellaunus, cousin of Vercingetorix. With them were
joined delegates from each country, who formed a council of direction
for the war. They began their march towards Alesia, full of ardour and
confidence: each was convinced that the Romans would retreat at the mere
sight of such imposing forces, especially when they found themselves
threatened at the same time by the sallies of the besieged, and by an
exterior army powerful in infantry and in cavalry.

Meanwhile, the day on which the besieged expected succour was past, and
their provisions were exhausted; ignorant, moreover, of what was taking
place among the Ædui, they assembled to deliberate on a final
resolution. The opinions were divided: some proposed to surrender,
others to make a sally, without waiting till their vigour would be
exhausted. But Critognatus, an Arvernan distinguished by his birth and
credit, in a discourse of singular and frightful atrocity, proposed to
follow the example of their ancestors, who, in the time of the war of
the Cimbri, being shut up in their fortresses, and a prey to want, ate
the men who were unable to bear arms, rather than surrender. When the
opinions were gathered, it was decided that that of Critognatus should
only be adopted at the last extremity, and that for the present they
would confine themselves to sending out of the place all useless mouths.
The Mandubii, who had received the Gaulish army within their walls,
were compelled to leave with their wives and children. They approached
the Roman lines, begged to be taken for slaves and supplied with bread.
Cæsar placed guards along the _vallum_, with orders not to admit them.

At length Commius and the other chiefs, followed by their troops, appear
before Alesia; they halt upon a neighbouring hill, scarcely 1,000 paces
from the circumvallation (the hill of Mussy-la-Fosse). The following day
they draw their cavalry out of their camp; it covered the whole plain of
Laumes. Their infantry establishes itself at a short distance on the
heights. The plateau of Alesia commanded the plain. At the sight of the
army of succour, the besieged meet together, congratulate each other,
yield to excess of joy, and then they rush out of the town, fill the
first fosse with fascines and earth, and all prepare for a general and
decisive sally.

Cæsar, obliged to face the enemy on two sides at once, disposed his army
on the two opposite lines of the retrenchments, and assigned to each his
post; he then ordered the cavalry to leave its camps, and to give
battle. From all the camps placed on the top of the surrounding hills,
the view extended over the plain, and the soldiers, in suspense, waited
for the issue of the event. The Gauls had mixed with their cavalry a
small number of archers and light-armed soldiers, to support them if
they gave way, and arrest the attack of the cavalry of the enemy. A good
number of the latter, wounded by these foot-soldiers, whom they had not
perceived until then, were obliged to retire from the battle. Then the
Gauls, confident in their numerical superiority, and in the valour of
their cavalry, believed themselves sure of victory; and from all sides,
from the besieged, as well as from the army of succour, there arose an
immense cry to encourage the combatants. The engagement was in view of
them all; no trait of courage or of cowardice remained unknown; on both
sides, all were excited by the desire of glory and the fear of
dishonour. From noon till sunset the victory remained uncertain, when
the Germans in Cæsar’s pay, formed in close squadrons, charged the
enemy, and put them to the rout; in their flight they abandoned the
archers, who were surrounded; then, from all parts of the plain, the
cavalry pursued the Gauls up to their camp without giving them time to
rally. The besieged, who had sallied out of Alesia, returned in
consternation, and almost despairing of safety.

After a day employed in making a great number of hurdles, ladders, and
hooks, the Gauls of the army of succour left their camp in silence
towards the middle of the night, and approached the works in the plain.
Then, suddenly uttering loud cries, in order to warn the besieged, they
throw their fascines, to fill up the fosse, attack the defenders of the
_vallum_ with a shower of sling-balls, arrows, and stones, and prepare
everything for an assault. At the same time, Vercingetorix, hearing the
cries from without, gives the signal with the trumpet, and leads his
troops out of the place. The Romans take in the retrenchments the places
assigned to them beforehand, and they spread disorder among the Gauls by
throwing leaden balls, stones of a pound weight, and employing the
stakes placed in the works beforehand; the machines rain down upon the
enemy a shower of darts. As they fought in the dark (the shields being
useless), there were in both armies many wounded. The lieutenants M.
Antony and C. Trebonius, to whom was entrusted the defence of the
threatened points, supported the troops that were too hardly pressed by
means of reserves drawn from the neighbouring redoubts. So long as the
Gauls kept far from the circumvallation, the multitude of their missiles
gave them the advantage; but when they approached, some became suddenly
entangled in the _stimuli_; others fell bruised into the _scrobes_;
others again were transpierced by the heavy _pila_ used in sieges, which
were thrown from the tops of the _vallum_ and the towers. They had many
disabled, and nowhere succeeded in forcing the Roman lines. When day
began to break, the army of succour retired, fearing to be taken in
their uncovered flank (the right side) by a sally from the camps
established on the mountain of Flavigny. On their side, the besieged,
after losing much valuable time in transporting the material for the
attack, and in making efforts to fill up the first fosse (the one which
was twenty feet wide), learnt the retreat of the army of succour before
they had reached the real retrenchment. This attempt having failed, like
the other, they returned into the town.

Thus twice repulsed with great loss, the Gauls of the army of succour
deliberated on what was to be done. They interrogate the inhabitants of
the country, who inform them of the position and the sort of defences
of the Roman camps placed on the heights.

To the north of Alesia there was a hill (Mont Réa) which had not been
enclosed in the lines, because it would have given them too great an
extent; the camp necessary on that side had, for this reason, to be
established on a slope, and in a disadvantageous position (_see Plate
25, camp D_); the lieutenants C. Antistius Reginus and C. Caninius
Rebilus occupied it with two legions. The enemy’s chiefs resolved to
attack this camp with one part of their troops, whilst the other should
assail the circumvallation in the plain of Laumes. Having decided on
this plan, they send their scouts to reconnoitre the localities,
secretly arrange among themselves the plan and the means of execution,
and decide that the attack shall take place at noon. They choose 60,000
men amongst the nations most renowned for their valour.
Vercasivellaunus, one of the four chiefs, is placed at their head.
