city in all Gaul. Rivers defended it on three sides, and on the fourth there were swamps and marshes which could be passed only by a narrow ridge. Within the walls the people had placed the best of their property, and Vercingetorix, against his judgment, consented, in pity for their entreaties, that Avaricum should be defended. A strong garrison was left inside. Vercingetorix entrenched himself in the forests sixteen miles distant, keeping watch over Caesar's communications. The place could only be taken by regular approaches, during which the army had to be fed. The Aedui were growing negligent. The feeble Boii, grateful, it seemed, for Caesar's treatment of them, exerted themselves to the utmost, but their small resources were soon exhausted. For many days the legions were without bread. The cattle had been driven into the woods. It came at last to actual famine.[3] "But not one word was heard from them," says Caesar, "unworthy of the majesty of the Roman people or their own earlier victories." He told them that if the distress became unbearable he would raise the siege. With one voice they entreated him to persevere. They had served many years with him, they said, and had never abandoned any enterprise which they had undertaken. They were ready to endure any degree of hardship before they would leave unavenged their countrymen who had been murdered at Gien. Vercingetorix, knowing that the Romans were in difficulties, ventured nearer. Caesar surveyed his position. It had been well chosen behind a deep morass. The legions clamored to be allowed to advance and attack him, but a victory, he saw, would be dearly purchased. No condemnation could be too severe for him, he said, if he did not hold the lives of his soldiers dearer than his own interest,[4] and he led them back without indulging their eagerness.
