There was a moment when it looked as though all Caesar’s work was to be swept away. He spent part of the year 54 in Britain. While he was away plans for a great rising were conceived. Soon after he returned all Gaul rose in a blaze. The first rising was put down. In 52 another and more serious movement took place with Vercingetorix at its head. The danger was greater than ever. It was the more serious that Caesar knew that in Rome his enemies were working against him. So great was it indeed that Caesar’s officers were in despair and begged him to retreat to some safe spot until reinforcements could be sent. But to wait for reinforcements would make things worse instead of better. The rebellion would gather force. It was by no means certain that Pompeius, now hand in glove with the Conservatives, would send him more troops. Pompeius would be glad to see his rival fail. Caesar was not going to give him that pleasure. And retreat in face of danger was never Caesar’s way. Always he went to meet it. So now. He delivered a blow at the very heart of the enemy’s position. Caesar’s capture of Alesia, the stronghold of Vercingetorix, and his defeat of the second great Gallic army that closed him in while he was blockading the town are among the great feats in the history of war. The odds were heavy against him. His army was in a position from which no luck, only the most brilliant generalship, could save it. Caesar not only saved it: he absolutely crushed the foe. Vercingetorix surrendered. The rebellion collapsed. By the end of the next year Gaul was under Caesar’s feet again. It was possible for him to turn his eyes and mind to Rome (50).

He did not want to quarrel with Pompeius. He had indeed from the first done everything in his power to prevent such a quarrel. But he saw that the old order of things in Rome was crumbling into ruin. If Pompeius and he could not rule together, one of them must rule alone. In the years of his absence Pompeius had moved more and more to the Conservative point of view. His jealousy of Caesar had grown. The long struggle came to a head when Caesar’s time in Gaul drew to an end.

MARCUS ANTONIUS

Caesar from his winter quarters at Ravenna declared that he was ready to disband his army and return to Rome as a private citizen as soon as Pompeius demobilized his troops. Pompeius actually had a larger force of men under arms than Caesar, including two legions which Caesar had borrowed and sent back to him. In the Senate Curio proposed that both generals should lay down their commands. This was agreed to. Pompeius refused. A few months later the question came up again. Curio, who had been to Ravenna, where Caesar was, read a letter from him. In this he said he would disarm, if Pompeius did the same. The Senate declared the letter was dangerous, and the man who wrote it dangerous. A friend of Pompeius then proposed that by a certain day Caesar, if not disarmed, should be regarded as a traitor. When Marcus Antonius and Cassius, another tribune, vetoed this, they were expelled from the Senate and threatened with swords by Pompeius’s adherents. Caesar could no longer have any doubt as to what awaited him in Rome. He explained how things stood to his soldiers: they cried to him to march on (49).

By Sulla’s law the Rubicon was the military boundary of Italy. No one might cross it under arms. Caesar paused for a moment on the bank; then suddenly crying, ‘The die is cast’, he crossed the river at the head of his men and marching with great speed entered Ariminum.
