Raymond of Tripoli allied with Saladin against Guy and allowed a Muslim garrison to occupy his fief in Tiberias, probably hoping that Saladin would help him overthrow Guy. Saladin, meanwhile, had pacified his Mesopotamian territories, and was now eager to attack the crusader kingdom; he did not intend to renew the truce when it expired in 1187. Before the truce expired, Raynald of Chatillon, the lord of Oultrejourdain and of Kerak and one of Guy's chief supporters, recognized that Saladin was massing his troops, and attacked Muslim caravans in an attempt to disrupt this. Guy was on the verge of attacking Raymond, but realized that the kingdom would need to be united in the face of the threat from Saladin, and Balian of Ibelin effected a reconciliation between the two during Easter in 1187. Saladin attacked Kerak again in April, and in May, a Muslim raiding party ran into the much smaller embassy on its way to negotiate with Raymond, and defeated it at the Battle of Cresson near Nazareth. Raymond and Guy finally agreed to attack Saladin at Tiberias, but could not agree on a plan; Raymond thought a pitched battle should be avoided, but Guy probably remembered the criticism he faced for avoiding battle in 1183, and it was decided to march out against Saladin directly. On July 4, 1187, the army of the kingdom was utterly destroyed at the Battle of Hattin. Raymond of Tripoli, Balian of Ibelin, and Reginald of Sidon escaped, but Raynald was executed by Saladin and Guy was imprisoned in Damascus.
