text: List of Second Anglo-Afghan War Victoria Cross recipients
Recipients

The Victoria Cross (VC) was awarded to 16 members of the British Armed Forces for action during the Second Afghan War of 1878-1880. The Victoria Cross is a military decoration awarded for valour in the face of the enemy to members of the armed forces of some Commonwealth countries and previous British Empire territories. The VC was introduced in Great Britain on 29 January 1856 by Queen Victoria to reward acts of valour during the Crimean War, and takes precedence over all other orders, decorations and medals. It may be awarded to a person of any rank in any service and to civilians under military command. The first ceremony was held on 26 June 1857, when Queen Victoria invested 62 of the 111 Crimean recipients in Hyde Park. The original Royal Warrant did not contain a specific clause regarding posthumous awards, although official policy was to not award the VC posthumously. Between 1897 and 1901, several notices were issued in the London Gazette regarding soldiers who would have been awarded the VC had they survived. In a partial reversal of policy in 1902, six of the soldiers mentioned were granted the VC, but not officially awarded the medal. In 1907, the posthumous policy was completely reversed and medals were sent to the next of kin of the six officers and men. The Victoria Cross warrant was not officially amended to explicitly allow posthumous awards until 1920, but one quarter of all awards for the First World War were posthumous. In the 19th century, Afghanistan was seen as an important buffer state to the north-west of British-ruled India. In 1866 Sher Ali Khan came to power and was initially well disposed towards Britain.
