Caesar - Gallic War- Book VII, 28 - Avaricum (Bourges)
The enemy were panic-stricken by the surprise, and when they were hurled down from the wall and the turrets they stood fast in wedge-formations in the marketplace and the more open places, with intent, if a movement were made from any side upon them, to deploy into line and fight to a finish. When they saw no one coming down on to the level ground, but that the troops were pouring round everywhere all along the wall, they feared that the hope of escape might be cut off altogether, and, casting away their arms, they made in a continuous rush for the farthest parts of the town ; and part, as they crowded one another at the marrow passage of the gates, were slain there by the troops, part after they had got out of the gates by the cavalry, and no one had any thought for plunder. in such fashion the troops, maddened by the massacre at Cenabum and the toil of the siegework, spared not aged men, nor women, and children. Eventually of all the number, which was about forty thousand, scarcely eight hundred, who had flung themselves out of the town when they heard the first shout, reached Vercingetorix in safety. He intercepted the refugees late at night in silence, fearing' that a mutiny might arise if they were met and pitied by the common sort : therefore, by stationing his own friends and the chiefs of states at some distance along the roads, he took steps to separate them and conduct them to their friends in the part of the camp allotted to each state from the beginning.
