The Second Battle of Panipat was fought between the Hemu, and Akbar.
After the death of Humayun, his 13 year old, Jalal Ud-Din Mohammad Akbar was declaredas the Emperor of leftover of the Mughal empire under the advisory of Bairam Khan. Their army clashed with Hemu at Panipat on the 5th of November 1556 in the famous war of Second battle of Panipat. Hemu’s initial charge shattered the Mughal flanks and cavalry. With their main strength annihilated, the severely disoriented and disorganized. Suddenly one arrow of Mughal Army hit the Hemu eye and first reaction to this was to remove the arrow and continue the fight. But because of incessant blood loss, Hemu eventually slumped. His troops assumed that he was dead and gets demoralized and in the end lost the war due to lack of co-ordination.
If Hemu would not have lost the war, he would have had active support of his Muslim subjects. Because Hemu never made any religious distinctions. He even convinced Afghan warriors, to call him Badshah and fight for him. Hemu was a firm believer in meritocracy and was probably the first secular king in medieval India. Going ahead into the future, there would have been no Shivaji and all the other Anti-Mughal Indian emperors. They existed because of the Mughals. And that, would have meant big problems for our eventual rulers, the British.
