The Franks of Acre did their best to maintain a position of cautious neutrality between the Mongols and the Mamluks. Despite their long history of enmity with the Mamluks, the Franks acknowledged that the Mongols were a greater threat, and after careful debate, chose to enter into a passive truce with their previous adversaries. The Franks allowed the Mamluk forces to move northward through Christian territory to engage the Mongols, in exchange for an agreement that the Franks could purchase any captured Mongol horses at a low price. The truce allowed the Mamluks to camp and re-supply near Acre, and engage the Mongols at Ain Jalut on . The Mongol forces were already depleted due to their main force withdrawing, so with the passive assistance of the Franks, the Mamluks were able to achieve a decisive and historic victory over the Mongols. The remainder of the Mongol army retreated to Cilician Armenia, where they were received and re-equipped by Hethum I. Ain Jalut marked a major turning point in the history of the Mongols, as it was the first major battle that they had lost, and set the western border for what had seemed an unstoppable expansion of the Mongol Empire.
