The Jewish Rebels and the 12th Legion
The Rebels.
Herod Agrippa II sent 2000 riders to help out the Jewish leaders in the upper city from the rebels, the lower city was already under rebel control. When Herod's Calvary arrived they were driven out and the archives were set on fire. Apparently setting the archives on fire would encourage the common people to join in a rebellion. They also captured and set fire to the Antonia fortress. It wasn't long before all of Jerusalem was under rebel control. At the end of summer during this rebellion Cestius Gallus, the Syrian governor, dispatched the 12th Legion from Antioch to deal with the rebellion in Jerusalem. When they arrived the Jews, being outnumbered, somehow managed to overcome them and forced them to retreat. The Jews chased after them and slaughtered his entire rear guard, which consisted of about 400 men. It is interesting that at this time the Jews, feeling very triumphant, minted their own coins.
