Akbar and his guardian Bairam Khan who, after learning of the loss of Agra and Delhi, marched to Panipat to reclaim the lost territories. It was a desperately contested battle but the advantage seemed to have tilted in favour of Hemu. Both the wings of the Mughal army had been driven back and Hemu moved his contingent of war elephants and cavalry forward to crush their centre. It was at this point that Hemu, possibly on the cusp of victory, was wounded when he was struck in the eye by a chance Mughal arrow and collapsed unconscious. Seeing him going down triggered a panic in his army which broke formation and fled. The battle was lost; 5,000 dead lay on the field of battle and many more were killed while fleeing. The spoils from the battle at Panipat included 120 of Hemu's war elephants whose destructive rampages so impressed the Mughals that the animals soon became an integral part of their military strategies.
