Jobert's magisterium ended with his death in 1177, and he was succeeded as Grand Master by Roger de Moulins. At that time, the Hospitallers formed one of the strongest military organizations of the kingdom, diverging from the origin mission of the Order. Among Roger's first actions was to urge Baldwin IV of Jerusalem to continue to vigorously prosecute the war against Saladin and, in November 1177, he participated in the Battle of Montgisard, winning a victory against the Ayyubids. Pope Alexander III called them back to the observance of the rule of Raymond du Puy between 1178 and 1180, issuing a bull that forbade them to take up arms unless they were attacked and urged them not to abandon the care of those sick and in poverty. Alexander III persuaded Roger to make a truce in 1179 with the Templar Odo de St Amand, then Grand Master, also a veteran of Montgisard.
