Convert Harm Into Benefit – Timur’s decision

Turco-Mongol commander and conqueror Timur (Tamerlane, 1336-1405), invaded northern India, attacking the Delhi Sultanate.
The battle between  Turco-Mongol conqueror and Indian forces took place in 1398.  The Indian army had war elephants armored with chain mail and poison on their tusks.

War elephants were a formidable force, as they could crushed morale and easily break through enemy formations.
