The Khyber Pass is a 53-kilometer (33-miles) passage through the Hindu Kush. It connects the northern frontier of what is now Pakistan with Afghanistan. During the three Afghan Wars the pass was the scene of numerous skirmishes between Anglo-Indian soldiers and local tribesmen who tried to control access to it.
