The key to Mughal power in India was its use of warhorses and also its control of the supply of superior warhorses from Central Asia. This was confirmed by victories in the Battle of Panipat, the Battle of Machhiwara, Battle of Dharmatpur, and in eyewitness accounts such as Father Monserrate, which primarily featured the use of traditional Turko-Mongol horse archer tactics rather than gunpowder. Cavalry warfare came to replace the logistically difficult elephant warfare and chaotic mass infantry tactics. Rajputs were co-opted by converting them into cavalry despite their traditions of fighting on foot. This was similar to the Marathas' service to the Deccan Sultanates.
