Finally the senate decreed that each general should give up one legion, to be used in a war with the Parthians. There was no such war, but it was pretended that there soon would be. Pompey agreed, but he called upon Caesar to send him back a legion which he had lent him three years before. Caesar did not hesitate to do so: he sent Pompey's legion and his own; but he took care to win the soldiers by giving each a valuable present as he went away. These legions were not sent to Asia, but to Capua. The senate wanted them for use nearer than Parthia. Caesar was then at Ravenna, a sea-side city on the southern limit of his province. South of it flowed a little stream called the Rubicon, which formed his border-line. Here he took a bold step. He sent a letter to the senate, offering to give up his command if Pompey would do the same. A violent debate followed in the senate, and a decree was passed that unless Caesar laid down his command by a certain day he should be declared an outlaw and enemy of Rome. At the same time the two consuls were made dictators, and the two tribunes who favored Caesar--one of them the afterwards famous Marc Antony--fled for safety from Rome. The decree of the senate was equivalent to a declaration of war. On the one side was Pompey, proud, over-confident, and unprepared. On the other was Caesar, knowing his strength, satisfied in the power of the money he had so freely distributed, and sure of his men. He called his soldiers together and asked if they would support him. They answered that they would follow wherever he led. At once he marched for the Rubicon, the limit of his province, to cross which stream meant an invasion of Italy and civil war. Plutarch tells us that he halted here and deeply meditated, troubled by the thought that to cross that stream meant the death of thousands of his countrymen. After a period of such meditation, he cried aloud, "The die is cast; let us go where the gods and the injustice of our foes direct!" and, spurring his horse forward, he plunged into the stream. This story, which has been effectively used by a great epic poet of Rome, probably relates what never happened. From all we know of Caesar, the question of bloodshed in attaining the aims of his ambition did not greatly trouble his mind. Yet the story has taken hold, and "to cross the Rubicon" has become a proverb, signifying the taking of a step of momentous importance. Caesar, after the legions sent the senate, had but a single legion left with him. He sent orders to others to join him with all haste, but they were distant. As for Pompey, knowing and despising the weakness of his rival, he had made no preparations. He had Caesar's two legions at Capua and one of his own at Rome, while thousands of Sulla's veterans were settled in the country round. "I have but to stamp my foot," he said, "and armed men will start from the soil of Italy."
