In the winter of 1297, Kadar, a noyan of the Mongol Chagatai Khanate invaded the Delhi Sultanate ruled by Alauddin Khalji. The Mongols ravaged the Punjab region, advancing as far as Kasur. Alauddin sent an army led by his brother Ulugh Khan (and probably Zafar Khan) to check their advance. This army defeated the invaders on 6 February 1298, killing around 20,000 of them, and forcing the Mongols to retreat.
