The success of Sulla in the East made it plain that he was the one to lead the army, but Marius was still ambitious to gain new laurels, and in order to prove that he was not too old to endure the hardships of a campaign, he went daily to the Campus Martius and exercised with the young men. His efforts proved vain, and he determined to take more positive measures. He procured the enactment of a law distributing the new citizens, who far out-numbered the old ones, among the tribes, knowing that they would vote in his favor. It was not without much opposition that this law was enacted, but Marius was then appointed, instead of Sulla, to lead the army against Pontus. Sulla meantime hastened to the army and obtained actual command of the soldiers, who loved him, caused the tribunes of Marius to be murdered, and left the old commander without support. Marius in turn raised another army by offering freedom to slaves, and with it attempted to resist Sulla, but in vain. He was obliged to fly, and a price was placed upon his head. He sailed for Africa, but was thrown back upon the shores of Italy, was cast into prison, and ordered to execution; but the slave commissioned to carry out the judgment was frightened by the flashing eyes of the aged warrior and refused to perform the act, as he heard a voice from the darkness of the cell haughtily asking: "Fellow, darest thou kill Caius Marius?" The magistrates, struck with pity and remorse, as they reflected that Marius was the preserver of Italy, let him go to meet his fate on other shores, and at last he found his way to Africa. The departure of both Marius and Sulla from Rome left it exposed to a new danger. As soon as Sulla had left for Pontus, Lucius Cornelius Cinna, one of the consuls, began to form a popular party, composed largely of the newly made citizens, for the purpose of overpowering the senate and recalling Marius. A frightful conflict ensued on a day of voting, and thousands were butchered in the struggle. Cinna was driven from the city, but received the support of a vast number of Italians, which enabled him to march again upon Rome.
