C. Julius Caesar, Gallic War

Which command having been most carefully obeyed, when any cohort had quitted the circle and made a charge, the enemy fled very precipitately. In the mean time, that part of the Roman army, of necessity, was left unprotected, and the weapons received on their open flank. Again, when they had begun to return to that place from which they had advanced, they were surrounded both by those who had retreated and by those who stood next them; but if, on the other hand, they wish to keep their place, neither was an opportunity left for valor, nor could they, being crowded together, escape the weapons cast by so large a body of men. Yet, though assailed by so many disadvantages, [and] having received many wounds, they withstood the enemy, and, a great portion of the day being spent, though they fought from day-break till the eighth hour, they did nothing which was unworthy of them. At length, each thigh of T. Balventius, who the year before had been chief centurion, a brave man and one of great authority, is pierced with a javelin; Q. Lucanius, of the same rank, fighting most valiantly, is slain while he assists his son when surrounded by the enemy; L. Cotta, the lieutenant, when encouraging all the cohorts and companies, is wounded full in the mouth by a sling.
