Initially the outbreak of violence had been an internal factional conflict between the Jews; those who were in favour of rebellion and those who were opposed. Huge loss of life occurred, including that of the former High Priest Ananias. The Roman garrison on Jerusalem's western border became besieged and was unable to assist those who opposed rebellion. Eventually, led by their commander Metilius, the garrison surrendered in exchange for unhindered passage from the city, but, led by Eliezar, the Jewish rebels slaughtered all the surrendered soldiers, except for Metilius, who was forced to convert to Judaism.
