When and what

This was in July 4, 1187 A.D. It was a war that Saladin had an army of about 20,000 men. It was a battle in northern Palestine. It marked the deafeat of the christian armies by the muslim named Saladin. The crusaders were camped about 20 miles from the sea of Galilee. It was hard for many of the fighters because they ran out of water. About 15,00 crusaders left to go to the relief of the city. Many of them left and turned back to where they came from. Most of the crusaders were slaughtered but Saladin spared the lives of most Christian lords and King Guy. A day after the battle, he started his campaign to take back the city of Jerusalem.
