The Battle of Jamrud was fought between the Emirate of Afghanistan and the Sikh Empire on 30 April 1837. The Sikhs were building up towards crossing the Khyber pass in order to invade Jalalabad. This led Afghan forces to confront the Sikh forces at Jamrud. The Afghan attempt to retake Peshawar from the invading Sikhs failed, but the killing of Sikh General Hari Singh Nalwa limited the Khyber pass as the western extent of the Sikh Empire, which was ended about a decade later by the British. The battle resulted in a victory for the Afghan forces. Amir Dost Muhammad defeated the Sikhs and took up the title of "Commander of the Faithful."
