The flaming camels charged forward, probably as a result of being set on fire, and scared the shit out of the elephants. Desperate to get away from the camels, the elephants turned and ran, which was unfortunate for the Indian infantry because they were standing right behind the elephants. Unable to control the stampede, Kahn could only watch helplessly as the elephants tore through his infantry, smashing their heads to atoms. The Indian army was routed in minutes.
Good times were had by all.
Timur went on to sack, pillage and rape the shitnoodles out of Delhi, but he wasn't done there. He had all 120 war elephants rounded up and forced to kneel in front of him, a ceremony during which even the elephants wondered what the hell was going on. Confident that nobody else would think to set their own units on fire, he added the elephants to his army and used them to take Ankara.
