After having, on his way, plundered Judæa, and sent prisoner to Rome its king Aristobulus, he crossed the desert, and arrived before Pelusium. A certain Archelaus, who was looked upon as a good general, and had served under Mithridates, was detained in Syria. Gabinius, informed that Queen Berenice wished to place him at the head of her army, and that she offered a large sum of money for his ransom, immediately set him at liberty, showing thereby as much avidity for riches as contempt for the Egyptians. He defeated them in several battles, slew Archelaus, and entered Alexandria, where he re-established Ptolemy on the throne, and the latter, it is said, gave him 10,000 talents.[687] In this expedition, Mark Antony, who was soon to be Cæsar’s quæstor, commanded the cavalry; he distinguished himself by his intrepidity and by his military talent.[688] This was the commencement of his fortune. Gabinius, if we believe Dio Cassius, took good care not to send an account of his conduct, but it was not long in becoming known, and he was compelled to return to Rome, where serious accusations awaited him. Unfortunately for him, when the period of his trial came on, Pompey, his protector, was no longer consul. Gabinius had to undergo in succession two accusations: he was acquitted of the first, on the double head of sacrilege and high treason, because he paid heavy bribes to his judges.[689] As to the second accusation, relating to acts of extortion, he experienced more difficulties. Pompey, who had been obliged to absent himself, in order to provide for the provisioning with which he was charged, hastened to the gates of Rome, which his office of proconsul did not allow him to enter, convoked an assembly of the people outside the Pomœrium, employed all his authority, and even read letters from Cæsar, in favour of the accused. Still more, he begged Cicero to undertake his defence, and Cicero accepted the task, forgetting the invectives with which he had overwhelmed Gabinius before the Senate. All these efforts failed: it was necessary to yield to the rage of the public opinion, skilfully excited by the enemies of Gabinius; and the latter, condemned, went into exile, where he remained until Cæsar’s dictatorship.[690] [Sidenote: Corruption of the Elections.]
