C. Julius Caesar, Gallic War

The situation of the camp was a rising ground, gently sloping from the bottom for about a mile. Thither they proceeded with great speed (in order that as little time as possible might be given to the Romans to collect and arm themselves), and arrived quite out of breath. Sabinus having encouraged his men, gives them the signal, which they earnestly desired. While the enemy were encumbered by reason of the burdens which they were carrying, he orders a sally to be made suddenly from two gates [of the camp]. It happened, by the advantage of situation, by the unskilfulness and the fatigue of the enemy, by the valor of our soldiers, and their experience in former battles, that they could not stand one attack of our men, and immediately turned their backs; and our men with full vigor followed them while disordered, and slew a great number of them; the horse pursuing the rest, left but few, who escaped by flight. Thus at the same time, Sabinus was informed of the naval battle and Caesar of victory gained by Sabinus; and all the states immediately surrendered themselves to Titurius: for as the temper of the Gauls is impetuous and ready to undertake wars, so their mind is weak, and by no means resolute in enduring calamities.
