C. Julius Caesar, Gallic War

Thus, was the contest long and vigorously carried on with doubtful success. When they could no longer withstand the attacks of our men, the one division, as they had begun to do, betook themselves to the mountain; the other repaired to their baggage and wagons. For during the whole of this battle, although the fight lasted from the seventh hour [i.e. 12 (noon) 1 P. M.] to eventide, no one could see an enemy with his back turned. The fight was carried on also at the baggage till late in the night, for they had set wagons in the way as a rampart, and from the higher ground kept throwing weapons upon our men, as they came on, and some from between the wagons and the wheels kept darting their lances and javelins from beneath, and wounding our men. After the fight had lasted some time, our men gained possession of their baggage and camp. There the daughter and one of the sons of Orgetorix was taken. After the battle about 130,000 men [of the enemy] remained alive, who marched incessantly during the whole of that night; and after a march discontinued for no part of the night, arrived in the territories of the Lingones on the fourth day, while our men, having stopped for three days, both on account of the wounds of the soldiers and the burial of the slain, had not been able to follow them. Caesar sent letters and messengers to the Lingones [with orders] that they should not assist them with corn or with any thing else; for that if they should assist them, he would regard them in the same light as the Helvetii. After the three days' interval he began to follow them himself with all his forces.
