Photograph of Baba Wali Kotal showing position of Ayub's guns in Kandahar from the 'Bellew Collection: Photograph album of Surgeon-General Henry Walter Bellew' taken by Sir Benjamin Simpson c.1881. Kandahar is the second largest city in Afghanistan and is situated in the south of the region. Ayub Khan of Herat was a son of Sher Ali, the Amir of Afghanistan from 1863 to 1879. During the Second Afghan War (1878-80), Ayub overwhelmed British forces at Kandahar and beseiged them in the city. The siege was eventually lifted British forces from Kabul led by FM Roberts. This view shows the mountain pass at which Ayub's guns were positioned.
