The surviving crusaders, joined by new arrivals from Europe, put Acre to a lengthy siege which lasted until 1191. After re-capturing Acre, Richard defeated Saladin at the Battle of Arsuf in 1191 and the Battle of Jaffa in 1192, recovering most of the coast for the Christians, but could not recover Jerusalem or any of the inland territory of the kingdom. The crusade came to an end peacefully, with the Treaty of Jaffa in 1192. Saladin allowed pilgrimages to be made to Jerusalem, allowing the crusaders to fulfil their vows, after which they all returned home. Local crusader barons set about rebuilding their kingdom from Acre and the other coastal cities.
