The Bolan Pass is a gap through the Toba Kakar Range of mountains on the border of Pakistan. The British took the threat of a Russian invasion of India via the Khyber and Bolan Passes very seriously so in 1837, a British envoy was sent to Kabul to gain support of the Emir, Dost Mohammed. In February of 1839, the British Army under Sir John Keane took 12,000 men through the Bolan Pass and entered Kandahar.
