Titus surrounded the city with three legions (Vth, XIIth and XVth) on the western side and one (Xth) on the Mount of Olives to the east. He put pressure on the food and water supplies of the inhabitants by allowing pilgrims to enter the city to celebrate Passover and then refusing them egress. Jewish raids continuously harassed the Roman Army, one of which nearly resulted in Titus being captured.
