C. Julius Caesar, Gallic War

When the townsmen perceived his design, being terrified by the recollection of the distress at Alesia , they began to dread similar consequences from a siege; and above all Luterius, who had experienced that fatal event, cautioned them to make provisions of corn; they therefore resolve by general consent to leave part of their troops behind, and set out with their light troops to bring in corn. The scheme having met with approbation, the following night Drapes and Luterius leaving two thousand men in the garrison, marched out of the town with the rest. After a few days' stay in the country of the Cadurci (some of whom were disposed to assist them with corn, and others were unable to prevent their taking it) they collected a great store. Sometimes also attacks were made on our little forts by sallies at night. For this reason Caninius deferred drawing his works round the whole town, lest he should be unable to protect them when completed, or by disposing his garrisons in several places, should make them too weak.
