The Battle of Ali Masjid, which took place on 21 November 1878, was the opening battle in the Second Anglo-Afghan War between the British forces, under Lieutenant-General Sir Samuel James Browne, and the Afghan forces, under Ghulam Haider Khan. The perceived offence of an Afghan general's refusal to allow a British envoy entrance to the country was used as an excuse to attack the fortress of Ali Masjid, as the opening battle in the war.
