Jalal ad-Din
After pursuing Jalal ad-Din into India from Samarkand and defeating him at the battle of Indus in 1221, Genghis Khan sent two tumens (20,000 soldiers) under commanders Dorbei the Fierce and Bala to continue the chase. The Mongol commander Bala chased Jalal ad-Din throughout the Lahore region and attacked outlying province Multan, and even sacked the outskirts of Lahore. Jalal ad-Din regrouped, forming a small army from survivors of the battle and sought an alliance, or even an asylum, with the Turkic rulers of Delhi Sultanate, but was turned down.
