The Mongols made dramatic victories in Persia and Syria, effectively destroying the Abbasid and Ayyubid Caliphates, and causing a shift of Islamic power to the Egyptian Mamluks in Cairo.
Baibars next turned his sights on Tripoli, and sent a letter to Bohemond threatening him with total annihilation, and taunting him for his alliance with the Mongol ruler Abaqa: Our yellow flags have repelled your red flags, and the sound of the bells has been replaced by the call: "Allâh Akbar!"
(...) Warn your walls and your churches that soon our siege machinery will deal with them, your knights that soon our swords will invite themselves in their homes (...) We will see then what use will be your alliance with Abagha"Bohemond begged for a truce, so as not to lose Tripoli as well.
Edward had landed in Acre on May 9, 1271, where he was soon joined by Bohemond and his cousin King Hugh of Cyprus and Jerusalem.
[2] Baibars, therefore, accepted Bohemond's offer of a truce in May, abandoned the siege of Tripoli, and instead concentrated his forces in Damas, in anticipation of future battles.
