Excerpts from Books and Wikipedia
"In April 1526, the Mughal leader, Babur, advanced on Delhi with a 15,000-strong army, including nomad horse archers and Ottoman Turk artillerymen with about twenty cannons (unknown in India at the time). To oppose him, Sultan Ibrahim Shah Lodi fielded an army of 40,000 and 100 war elephants, but no artillery. Driven from their homeland in Ferghana, Central Asia, by the Uzbeks in 1501, the Mughals (so-called because they claimed Mongol descent) had migrated east under the leadership of Babur and founded a new principality at Kabul in 1504. In 1515, Babur began a series of raids into northern India, then under the rule of the Lodi sultanate of Delhi. When the Punjab rebelled against Sultan Ibrahim, Babur took the opportunity to seize Lahore. He was soon driven out, but in 1525 returned in greater strength and conquered the whole Punjab. . . .. Babur's cannons proved decisive--they panicked Ibrahim's elephants into flight, trampling and disorganizing his army as they ran. . . . Although Mughal losses were also heavy, Babur managed to capture Delhi a week later, thereby founding the Mughal Empire that would dominate India for 200 years." [1001 Days]
