Photograph of the Lahore Gate, with an Afghan group seated at the roadside in the foreground, taken by the Bengal Sappers and Miners, an engineering arm of the Indian Army in c. 1879 during the course of the Second Anglo-Afghan War (1878-80). The gateway is an entry point to the Bala Hissar fortress at Kabul, Afghanistan. This is an ancient citadel, dating back to the time of the White Huns in the 5th century and home to some of Afghanistan’s most important kings. It is located to the south of Kabul in a prominent position overlooking the city. The fortress was originally divided into two parts, the lower fortress contained three royal palaces, stables and barracks and the upper fortress housed the armoury and dungeon of Kabul. In the 19th century the British were engaged in conflicts with Afghanistan due to British fear of Russian encroachment on their Indian colony and internal divisions within Afghanistan. The Bala Hissar was occupied intermittently by the British and was partially destroyed by General Roberts in retaliation for the killing of the British resident, Cavagnari and his mission in 1879.
