Siege of Multan (1848–1849)
The siege of Multan began on 19 April 1848 and lasted until 22 January 1849, and saw fighting around Multan (in present-day Punjab, Pakistan) between the British East India Company and the Sikh Empire. It began with a rebellion against a ruler imposed by the East India Company, which precipitated the Second Anglo-Sikh War, and ended when the last defenders of the city surrendered to British forces.
