Measures Adopted by the Allies for Their Security
The permanence of the arrangements made seemed also sufficiently secured. The consulship was, at least for the next year, entrusted to safe hands. The public believed at first, that it was destined for Pompeius and Crassus themselves; the holders of power however preferred to procure the election of two subordinate but trustworth men of their party--Aulus Gabinius, the best among Pompeius' adjutants, and Lucius Piso, who was less important but was Caesar's father-in-law-- as consuls for 696. Pompeius personally undertook to watch over Italy, where at the head of the commission of twenty he prosecuted the execution of the agrarian law and furnished nearly 20,000 burgesses, in great part old soldiers from his army, with land in the territory of Capua.
Caesar's north-Italian legions served to back him against the opposition in the capital. There existed no prospect, immediately at least, of a rupture among the holders of power themselves. The laws issued by Caesar as consul, in the maintenance of which Pompeius was at least as much interested as Caesar, formed a guarantee for the continuance of the breach between Pompeius and the aristocracy--whose heads, and Cato in particular, continued to treat these laws as null--and thereby a guarantee for the subsistence of the coalition. Moreover, the personal bonds of connection between its chiefs were drawn closer.
