C. Julius Caesar, Gallic War

On the seventh day of the attack, a very high wind having sprung up, they began to discharge by their slings hot balls made of burned or hardened clay, and heated javelins, upon the huts, which, after the Gallic custom, were thatched with straw. These quickly took fire, and by the violence of the wind, scattered their flames in every part of the camp. The enemy following up their success with a very loud shout, as if victory were already obtained and secured, began to advance their towers and mantelets, and climb the rampart with ladders. But so great was the courage of our soldiers, and such their presence of mind, that though they were scorched on all sides, and harassed by a vast number of weapons, and were aware that their baggage and their possessions were burning, not only did no one quit the rampart for the purpose of withdrawing from the scene, but scarcely did any one even then look behind; and they all fought most vigorously and most valiantly. This day was by far the most calamitous to our men; it had this result, however, that on that day the largest number of the enemy was wounded and slain, since they had crowded beneath the very rampart, and the hindmost did not afford the foremost a retreat. The flame having abated a little, and a tower having been brought up in a particular place and touching the rampart, the centurions of the third cohort retired from the place in which they were standing, and drew off all their men: they began to call on the enemy by gestures and by words, to enter if they wished; but none of them dared to advance. Then stones having been cast from every quarter, the enemy were dislodged, and their tower set on fire.
