In 1299, Hethum, recovered at least partially from his blindness, ousted Constantin and once again resumed the crown. Soon thereafter, he again sought assistance from Ghazan's Mongols, and fought against the Mamluks in Syria. The combined forces achieved a major victory at the December 1299 Battle of Wadi al-Khazandar (sometimes called the Battle of Homs), taking Damascus, and Hethum was able to regain all of the Armenian territory which had previously been lost to the Mamluks. One group of Mongols split off from Ghazan's army and was even able to launch some Mongol raids into Palestine, pursuing the retreating Egyptian Mamluk troops as far south as Gaza, pushing them back to Egypt.
