The Battle of Jamrud is fought between the Emirate of Afghanistan and the Sikh Empire on April 30, 1837.
The Sikhs are building up towards crossing the Khyber pass and capturing Jalalabad.
The Afghan attempt to retake Peshawar from the invading Sikhs failed, but the killing of Sikh General Hari Singh Nalwa limits the Khyber pass as the western extent of the Sikh Empire.
