the surrender of the lands around Acre. Philip, before leaving, had entrusted his prisoners to Conrad, but Richard forced him to hand them over to him. Richard feared his forces being bottled up in Acre as he believed his campaign could not advance with the prisoners in train. He, therefore, ordered all the prisoners executed. He then moved south, defeating Saladin's forces at the Battle of Arsuf north of Jaffa on 7 September 1191. Saladin attempted to harass Richard's army into breaking its formation in order to defeat it in detail. Richard maintained his army's defensive formation, however, until the Hospitallers broke ranks to charge the right wing of Saladin's forces. Richard then ordered a general counterattack, which won the battle. Arsuf was an important victory. The Muslim army was not destroyed, despite the considerable casualties it suffered, but it did rout; this was considered shameful by the Muslims and boosted the morale of the Crusaders. In November 1191, following the fall of Jaffa, the Crusader army advanced inland towards Jerusalem. The army then marched to Beit Nuba, only 12 miles from Jerusalem. Muslim morale in Jerusalem was so low that the arrival of the Crusaders would probably have caused the city to fall quickly. However, the weather was appallingly bad, cold with heavy rain and hailstorms; this, combined with the fear that the Crusader army, if it besieged Jerusalem, might be trapped by a relieving force, led to the decision to retreat back to the coast. Richard attempted to negotiate with Saladin, but this was unsuccessful. In the first half of 1192, he and his troops refortified Ascalon. An election forced Richard to accept Conrad of Montferrat as King of Jerusalem, and he sold Cyprus to his defeated protégé, Guy. Only days later, on 28 April 1192, Conrad was stabbed to death by the Assassins before he could be crowned. Eight days later Richard's own nephew Henry II of Champagne was married to the widowed Isabella, although she was carrying Conrad's child. The murder was never conclusively solved, and Richard's contemporaries widely suspected his involvement. The crusader army made another advance on Jerusalem, and in June 1192 it came within sight of the city before being forced to retreat once again, this time because of dissension amongst its leaders. In particular, Richard and the majority of the army council wanted to force Saladin to relinquish Jerusalem by attacking the
