The long-famed military acumen of the Templars began to stumble in the 1180s. On July 4, 1187, came the disastrous Battle of the Horns of Hattin, a turning point in the Crusades. It again involved Saladin, who had been beaten back by the Templars in 1177 in the legendary Battle of Montgisard near Tiberias, but this time Saladin was better prepared. Further, the Grand Master of the Templars was involved in this battle, Gerard de Ridefort, who had just achieved that lifetime position a few years earlier. He was not known as a good military strategist, and made some deadly errors, such as venturing out with his force of 80 knights without adequate supplies or water, across the arid hill country of Galilee. The Templars were overcome by the heat within a day, and then surrounded and massacred by Saladin's army. Within months Saladin captured Jerusalem.
