It was against Quintus Caepio that their attacks were first directed; and justly, in so far as he had primarily occasioned the defeat of Arausio by his insubordination, even apart from the probably well-founded but not proved charge of embezzling the Tolosan booty; but the fury which the opposition displayed against him was essentially augmented by the fact, that he had as consul ventured on an attempt to wrest the posts of jurymen from the capitalists.(22) On his account the old venerable principle, that the sacredness of the magistracy should be respected even in the person of its worst occupant, was violated; and, while the censure due to the author of the calamitous day of Cannae had been silently repressed within the breast, the author of the defeat of Arausio was by decree of the people unconstitutionally deprived of his proconsulship, and--what had not occurred since the crisis in which the monarchy had perished--his property was confiscated to the state-chest (649?). Not long afterwards he was by a second decree of the burgesses expelled from the senate (650). But this was not enough; more victims were desired, and above all Caepio's blood. A number of tribunes of the people favourable to the opposition, with Lucius Appuleius Saturninus and Gaius Norbanus at their head, proposed in 651 to appoint an extraordinary judicial commission in reference to the embezzlement and treason perpetrated in Gaul; in spite of the de facto abolition of arrest during investigation and of the punishment of death for political offences, Caepio was arrested and the intention of pronouncing and executing in his case sentence of death was openly expressed. The government party attempted to get rid of the proposal by tribunician intervention; but the interceding tribunes were violently driven from the assembly, and in the furious tumult the first men of the senate were assailed with stones. The investigation could not be prevented, and the warfare of prosecutions pursued its course in 651 as it had done six years before; Caepio himself, his colleague in the supreme command Gnaeus Mallius Maximus, and numerous other men of note were condemned: a tribune of the people, who was a friend of Caepio, with difficulty succeeded by the sacrifice of his own civic existence in saving at least the life of the chief persons accused.(23) Marius Commander-in-Chief
