A revolt in Gaul at that time would endanger all Cæsar's chances for success in Rome. Should his army be overcome he would have no means of enforcing his power there, and a defeat would utterly destroy the prestige that he had built up among the Romans at the cost of so much money and labor. So Cæsar hurried across the Alps and after maneuvering his legions in a manner that showed to the world he was a genius in the art of war, he succeeded in surrounding the greater part of the forces of Vercingetorix.
To save his comrades Vercingetorix gave in to Cæsar, and galloped out of his stronghold to give up his sword. He laid his arms at Cæsar's feet and surrendered himself as a captive. Cæsar kept him as a prisoner for a number of years, after which time he was taken to Rome and forced to walk in the triumph of the conqueror. Then he suffered the fate of the captives of Rome. He was shut up in a dungeon and strangled, and his body was thrown upon one of the refuse heaps of the mighty city.
Continued success in Gaul had by this time made Cæsar's name so great in Rome that the Senate had grown to fear him. Pompey too was jealous of his growing power, and Cæsar was finally ordered by the Senate to disband his army. The two officers of the people, called the tribunes, whose names were Antony and Cassius, vetoed this act on the part of the Senate, and were hunted from Rome and fled to Cæsar's camp for refuge.
Then the Senate, wildly afraid that Cæsar would return at the head of his troops and become a tyrant like Sulla, declared war against Cæsar and put in Pompey's hands the task of humbling his former friend. Cæsar had no intention of disbanding his troops. His soldiers loved him deeply and would follow wherever he led them. And Cæsar exhorted his men to stand by him, promising them honor and riches if he should succeed in overcoming his enemies at Rome, and the men with wild cheers swore that they would follow him to the death.
At the head of a powerful and well disciplined army that was devoted to him, Cæsar advanced on Rome. When he came to a stream called the Rubicon, which marked the limit of his power as governor of Gaul, he hesitated for a brief time, as there was still time for him to draw back from his tremendous venture had he seen fit to do so--but at length he plunged into the stream with the remark, "The die is cast," and advanced upon the city that he intended to win for himself.
