Explanation:

The Battle of Gujrat was a decisive battle in the Second Anglo-Sikh War, fought on 21 February 1849, between the forces of the East India Company, and a Sikh army in rebellion against the Company's control of the Sikh Empire, represented by the child Maharaja Duleep Singh who was in British custody in Lahore. The Sikh army was defeated by the British regular and Bengal Army forces of the British East India Company. After it capitulated a few days later, the Punjab was annexed to the East India Company's territories and Duleep Singh was deposed.
In particular,Britishers brought large numbers of heavy guns with them. Gough, who had now received word of his dismissal but who remained in command until formally relieved, advanced against the Sikh army. He had three infantry divisions and a large cavalry force, with 100 guns of various weights and calibres.
Early on 21 February, Gough advanced against this position. When the Sikh artillery opened fire and disclosed their position, Gough deployed his large numbers of heavy guns against them. In a three-hour artillery duel, the Sikhs were forced to abandon their guns. Sikh and Indian sources were later to refer to the battle as the "Battle of the Guns".
