The Battle of Hattin, which took place on July 4, 1187, was an armed conflict between the armies of the Sultan Saladin and King Guy of Jerusalem. On the evening of July 3, scouts reported to Guy that Saladins troops were preparing to attack them when they marched toward Lake Tiberias. Guy, undaunted, ordered his troops to push on to the lake.
Saladin, excited that the Crusaders fell into his trap, became careless and ordered Gobi's division to take the conscripts and move to Jerusalem, thus losing 1/2 of his forces. His cavalry then charged the Crusaders, but Guys archers broke the charge. Christian knights under Count Raymond, meanwhile, broke through Saladins weak defense between the Horns of Hattin and reached the lake. Now at a defensible position, Raymond's archers and crossbowmen mounted the Horns and began raining arrows and bolts of Saladins right flank.
That afternoon, as Saracen casualties mounted, Saladin was forced to retreat to safety. With the day won by the Christians, the Pope in Rome calls for a crusade.
