In the seventeenth year of Agrippa's reign (corresponding with the 12th year of Nero's reign, or 65/66 AD), Agrippa tried desperately to avert a war with Rome, when he saw his countrymen generally disposed to fight against Rome, because of certain insults and abuses they had had under the Roman procurator, Gessius Florus. At this time, they had broken-off the cloisters leading from Antonia Fortress to the Temple Mount where Roman soldiers were wont to keep guard during the Jewish holidays, and they refused to pay the tribute which was due to Caesar. Agrippa convened the people and urged instead that they tolerate the temporary injustices done to them and submit themselves to Roman hegemony. At length, Agrippa failed to prevent his subjects from rebelling, whereas, during a certain holiday when the Roman governor of Syria, Cestius Gallus, had passed through Judea to quell the rebellion, he was routed by Jewish forces. By 66 the citizenry of Jerusalem expelled their king, Agrippa, and his sister, Berenice, from Jerusalem. During the First Jewish-Roman War of 66-73, he sent 2,000 men, archers and cavalry, to support Vespasian, showing that, although a Jew in religion, he was entirely devoted to the Roman Empire. He accompanied Titus on some campaigns, and was wounded at the siege of Gamla. After the capture of Jerusalem, he went with his sister Berenice to Rome, where he was invested with the dignity of praetor and rewarded with additional territory.
