Hulagu gave command to his army to march into Syria. He summoned Bedr ud din Lulu, who, excused because of great age, had to send his son, Melik Salih Ismail, with the troops of Mosul. When this young man arrived at the camp of the Mongols Hulagu made him marry a daughter of Jelal ud din, the last Shah of Kwaresm. Kita Buga went with the vanguard, Sinkur, a descendant of Kassar, and Baidju led the right wing, the left was commanded by Sunjak. Hulagu set out with the center, September 12, 1259. He passed Hakkar, where all Kurds whom they met were cut down by the sword, not one man being spared. On entering Diarbekr Hulagu took Jeziret on the Tigris, and sent his son Yshmut with Montai Noyon to take Mayafarkin, an old and famous town northeast of Diarbekr, whose Eyubite prince, Kamil Nasir ud din Mohammed, he wished to punish for hostility to the Mongols. He was all the more angry since this man had been received well years before that by Mangu the Grand Khan, and given letters which put his lands under that sovereign’s protection. Hulagu accused Kamil now of crucifying a Syrian priest, who had come to his court with the Grand Khan’s safe-conduct; with having expelled Mongol prefects, and with having sent a corps of troops to help Bagdad at demand of the Kalif—these troops when they had gone half the distance turned back on learning that the capital had fallen. To finish all, Kamil had been in Damascus asking Prince Nassir to march on the Mongols. It was at this time that Hulagu sent his son to punish Prince Kamil, who had barely returned with vain promises when he found himself sealed in at Mayafarkin securely. Hulagu summoned next to obedience Saïd Nedjmud din el Gazi, Prince of Mardin. That prince sent his son, Mozaffer Kar Arslan, his chief judge, and an emir with presents, and a letter in which he alleged severe illness as his excuse for not giving personal homage. Hulagu sent the following answer, making the judge go alone with it to his master: “The prince says that he is ill, he says this because he fears Nassir of Syria, and thinks that if I should triumph he must be friendly with me hence he feigns this illness, and if I fail he will be on good terms with Nassir.” The son of Bedr ud din Lulu was sent against Amid. Hulagu himself took Nisibin. He had encamped close to Harran, and received the submission of its people, who were spared, as were also the inhabitants of Koha, who followed the example of Harran; but the people of Sarudj, who sent no deputation to beg for their lives, were cut down with the sword every man of them.
