for an advance on Jerusalem. During this period, Richard and Saladin passed envoys back and forth, negotiating the possibility of a truce. Richard proposed that his sister Joan should marry Saladin's brother and that Jerusalem could be their wedding gift. However, Saladin rejected this idea when Richard insisted that Saladin's brother convert to Christianity. Richard suggested that his niece Eleanor, Fair Maid of Brittany be the bride instead, an idea that Saladin also rejected. In January 1192, Richard's army occupied Beit Nuba, just twelve miles from Jerusalem, but withdrew without attacking the Holy City. Instead, Richard advanced south on Ascalon, where he restored the fortifications. In July 1192, Saladin tried to threaten Richard's command of the coast by attacking Jaffa. The city was besieged, and Saladin very nearly captured it; however, Richard arrived a few days later and defeated Saladin's army in a battle outside the city. The Battle of Jaffa (1192) proved to be the last military engagement of the Third Crusade. After Richard reoccupied Jaffa and restored its fortifications, he and Saladin again discussed terms. At last Richard agreed to demolish the fortifications of Ascalon, while Saladin agreed to recognize Crusader control of the Palestinian coast from Tyre to Jaffa. The Christians would be allowed to travel as unarmed pilgrims to Jerusalem, and Saladin's kingdom would be at peace with the Crusader states for the following three years. Death Saladin died of a fever on 4 March 1193 () at Damascus, not long after King Richard's departure. In Saladin's possession at the time of his death were one piece of gold and forty pieces of silver. He had given away his great wealth to his poor subjects, leaving nothing to pay for his funeral. He was buried in a mausoleum in the garden outside the Umayyad Mosque in Damascus, Syria. Originally the tomb was part of a complex which also included a school, Madrassah al-Aziziah, of which little remains except a few columns and an internal arch. Seven centuries later, Emperor Wilhelm II of Germany donated a new marble sarcophagus to the mausoleum. However, the original sarcophagus was not replaced; instead, the mausoleum, which is open to visitors, now has two sarcophagi: the marble one placed on the side and the original wooden one, which covers Saladin's tomb. Family Imad ad-Din al-Isfahani compiled a list of Saladin's sons along with their dates of birth, according to information provided
