In September 1281 the Mongols returned, with 50,000 of their own troops, plus 30,000 others including Armenians under Leo III, Georgians, and 200 Knights Hospitaller from Marqab, who sent a contingent even though the Franks of Acre had agreed a truce with the Mamluks. The Mongols and their auxiliary troops fought against the Mamluks at the Second Battle of Homs on October 30, 1281, but the encounter was indecisive, with the Sultan suffering heavy losses. In retaliation, Qalawun later besieged and captured the Hospitaller fortress of Marqab in 1285.
