Qutuz responded by killing the six envoys, "halving them at the waist," and displaying their heads on Bab Zuweila. He then allied with a fellow Mamluk, Baibars, to defend Islam against the Mongol threat. Their combined forces, perhaps 20,000 strong, marched north to confront the Mongolian army, which was led by Kitbuqa. This clash of the Mamluk and Mongolian armies was known as the Battle of Ain Jalut, and resulted in a resounding Mamluk victory. The battle was pivotal for the region, as it marked the first time that the seemingly unstoppable Mongols suffered defeat. The battle was a turning point in the expansion of their empire, and effectively set their western border, while confirming the Mamluks as the dominant force in the Middle East, and the beginning of the end of the Mongol presence in the area.
