At which 1187 battle did Saladin defeat the Crusader army and capture King Guy of Lusignan?

Saladin defeated the Crusader army and captured King Guy of Lusignan at the Battle of Hattin in 1187.

The battle was fought near the twin hills known as the Horns of Hattin in present-day Israel. Saladin’s Ayyubid army cut the Crusaders off from reliable water while they marched toward Tiberias. Heat, thirst, smoke, and repeated attacks weakened the Christian force before the decisive assault.

The Crusader army included many knights and senior nobles, but it was badly positioned and unable to reach the Sea of Galilee. The True Cross, a revered relic carried by the Crusaders, was also captured during the defeat.

After the battle, Saladin captured Jerusalem in October 1187. He treated several high-ranking prisoners differently: King Guy was eventually released, while Raynald of Châtillon was executed. Hattin therefore became the turning point that triggered the Third Crusade, led in part by Richard I of England and Philip II of France.
