he saw the Gauls within the walls of the town, he determined to keep them there. He at once ordered his men to set to work to dig trenches, and to build forts round the walls, that no one might escape.
But one night, when it was dark, the young Gaul sent messengers to summon the neighbouring tribes to come to his aid.
The messengers passed the enemy's lines in safety, and galloped swiftly away to rouse their people. In a short time a large army of 300,000 of the bravest men in Gaul were marching to the aid of Vercingetorix.
Thus it was that one day, as the Romans worked at the trenches and the forts, they were unexpectedly attacked by a new Gallic army.
Vercingetorix seized the same moment to sally out of Alesia with his men, and the Romans were caught between two foes. For four days a terrible struggle raged, and then, as was almost always the way, Cæsar and his legions proved victorious.
To save his army, Vercingetorix gave himself up to the Romans, flinging first his arms and then himself at the feet of the conqueror. But Cæsar had no pity for the foe he had vanquished, and carried off the brave young Gaul to Rome to adorn his triumph.
For two years longer Cæsar stayed in Gaul, and although he fought some battles and put down some rebellions, his chief work was to pass laws that would make the Gauls content to live under the protection of Rome.
By the end of the two years Cæsar had shown that he was not only a great general, but that he was also a great ruler of men.
