Gallic War (3.2-3.6)

When several days had elapsed in winter quarters, and he had ordered corn to be brought in he was suddenly informed by his scouts that all the people had gone off in the night from that part of the town which he had given up to the Gauls, and that the mountains which hung over it were occupied by a very large force of the Seduni and Veragri. It had happened for several reasons that the Gauls suddenly formed the design of renewing the war and cutting off that legion. First, because they despised a single legion, on account of its small number, and that not quite full (two cohorts having been detached, and several individuals being absent, who had been dispatched for the purpose of seeking provision); then, likewise, because they thought that on account of the disadvantageous character of the situation, even their first attack could not be sustained [by us] when they would rush from the mountains into the valley, and discharge their weapons upon us. To this was added, that they were indignant that their children were torn from them under the title of hostages, and they were persuaded that the Romans designed to seize upon the summits of the Alps , and unite those parts to the neighboring province [of Gaul], not only to secure the passes, but also a constant possession.

Having received these tidings, Galba, since the works of the winter-quarters and the fortifications were not fully completed, nor was sufficient preparation made with regard to corn and other provisions (since, as a surrender had been made, and hostages received, he had thought he need entertain no apprehension of war), speedily summoning a council, began to anxiously inquire their opinions. In which council, since so much sudden danger had happened contrary to the general expectation, and almost all the higher places were seen already covered with a multitude of armed men, nor could [either] troops come to their relief, or provisions be brought in, as the passes were blocked up [by the enemy]; safety being now nearly despaired of, some opinions of this sort were delivered: that, "leaving their baggage, and making a sally, they should hasten away for safety by the same routes by which they had come thither." To the greater part, however, it seemed best, reserving that measure to the last, to await the issue of the matter, and to defend the camp.

A short time only having elapsed, so that time was scarcely given for arranging and executing those things which they had determined on, the enemy, upon the signal being given, rushed down [upon our men] from all parts, and discharged stones and darts, upon our rampart. Our men at first, while their strength was fresh, resisted bravely, nor did they cast any weapon ineffectually from their higher station. As soon as any part of the camp, being destitute of defenders, seemed to be hard pressed, thither they ran, and brought assistance. But they were over-matched in this, that the enemy when wearied by the long continuance of the battle, went out of the action, and others with fresh strength came in their place; none of which things could be done by our men, owing to the smallness of their number; and not only was permission not given to the wearied [Roman] to retire from the fight, but not even to the wounded [was liberty granted] to quit the post where he had been stationed, and recover.

When they had now been fighting for more than six hours, without cessation, and not only strength, but even weapons were failing our men, and the enemy were pressing on more rigorously, and had begun to demolish the rampart and to fill up the trench, while our men were becoming exhausted, and the matter was now brought to the last extremity, P. Sextius Baculus, a centurion of the first rank, whom we have related to have been disabled by severe wounds in the engagement with the Nervii, and also C. Volusenus, a tribune of the soldiers, a man of great skill and valor, hasten to Galba, and assure him that the only hope of safety lay in making a sally, and trying the last resource. Whereupon assembling the centurions, he quickly gives orders to the soldiers to discontinue the fight a short time, and only collect the weapons flung [at them], and recruit themselves after their fatigue, and afterward, upon the signal being given, sally forth from the camp, and place in their valor all their hope of safety.

They do what they were ordered; and, making a sudden sally from all the gates [of the camp], leave the enemy the means neither of knowing what was taking place, nor of collecting themselves. Fortune thus taking a turn, [our men] surround on every side, and slay those who had entertained the hope of gaining the camp and having killed more than the third part of an army of more than 30,000 men (which number of the barbarians it appeared certain had come up to our camp), put to flight the rest when panic-stricken, and do not suffer them to halt even upon the higher grounds. All the forces of the enemy being thus routed, and stripped of their arms, [our men] betake themselves to their camp and fortifications. Which battle being finished, inasmuch as Galba was unwilling to tempt fortune again, and remembered that he had come into winter quarters with one design, and saw that he had met with a different state of affairs; chiefly however urged by the want of corn and provision, having the next day burned all the buildings of that village, he hastens to return into the province; and as no enemy opposed or hindered his march, he brought the legion safe into the [country of the] Nantuates, thence into [that of] the Allobroges, and there wintered.
