Answers
Step-by-step explanation:
Hearing of the size of Ibrahim's army, Babur secured his right flank against the city of Panipat, while digging a trench covered with tree branches to secure his left flanks. In the centre, he placed 700 carts tied together with ropes. Between every two carts, there were breastworks for his matchlock men. Babur also ensured that there was enough space for his soldiers to rest their guns and fire. Babur referred to this method as the "Ottoman device" due to its previous use by the Ottomans during the Battle of Chaldiran.[12]
When Ibrahim's army arrived, he found the approach to Babur's army too narrow to attack. While Ibrahim redeployed his forces to allow for the narrower front, Babur quickly took advantage of the situation to flank (tulghuma) the Lodi army.[2] Many of Ibrahim's troops were unable to get into action, and fled when the battle turned against them.[13] Ibrahim Lodi was killed while trying to retreat and beheaded. 20,000 Lodi soldiers were killed in the battle.[2]
