This is what we are all about the pogroms: there was a war, and it smashed against the Jews of the Jews. In May '66 the Zealots attacked the Romans near Jerusalem. Legions retreated cautiously, and the Zealots were delighted by his own victory. In November '66 the governor of Syria, Cestius Gallus came up against Jerusalem, unable to take the city and retreated. Jews (including the mouth of Josephus) was told that destroyed almost all the army of Cestius Gallus. The Romans do not have such information; They somehow thought that Cestius Gallus led his legions, and rightly so - there is no need to destroy the soldiers, if the Jews themselves cut each other.
