artillery of the Turks, and Ismail after a disastrous defeat fled and escaped. Selim I, his provisions failing, returned westward and spent the winter at Amasia. In the spring taking the field again, he attacked the bey of Dulkadirids who as Egypt's vassal had stood aloof, and sent his head with tidings of the victory to Mamluk Sultan Al-Ashraf Qansuh al-Ghuri. Selim I later overran Diyarbakır and Iraq, taking Roha, Nineveh, the Nineveh Plains, Nisibin, Mosul and other cities. Secure now against Shah Ismail I, a larger project dawned upon Selim I; it was the conquest of Egypt, and the fact that the invasion must be made from Syria. With no anxieties toward the North, he could now safely make the advance, and so in the spring of 1516 CE he drew together for this end a great and well-appointed army; and with the view of deceiving Egypt, represented his object to be the further pursuit of Shah Ismail I. Fall of the Mamluk Sultanate Leaving Al-Ashraf Tuman bay II the Vizier, in charge, Al-Ashraf Qansuh al-Ghuri marched against the Ottoman Turks. He was defeated by Selim I at the Battle of Marj Dabiq, north of Aleppo, on 24 August 1516; the betrayal of two Mamluk leaders Janbirdi al-Ghazali and Khayr Baig led to the Mamluk defeat and to the death of the Sultan Qansuh. This marked the end of Mamluk control of the Middle East that eventually passed to the Ottomans. Al-Ashraf Qansuh al-Ghuri himself fell upon the field and his head was carried to the Conqueror. Accounts however vary to how he met his end. It is said that Khayr Baig spread report of his death to precipitate the Egyptian flight. According to some the Sultan was found alive on the field, and his head cut off and buried to prevent its falling into the enemy's hands. The Ottoman account is that he was beheaded by an Ottoman soldier whom Sultan Selim I would have put to death, but afterwards pardoned. Al-Ashraf Qansuh al-Ghuri had reigned a little more than 15 years. Of his private life and domestic administration we know but little, for as we reach the later years of the Mamluk Sultanate, details become too scanty for a judgment. He could, as we have seen, be cruel and extortionate, but so far as our information goes, there is less to say against him than against most
