In some cases where a battle honour was not granted, a special distinction has been substituted. For example, soldiers of The Rifles wear a cap badge on both the front and the rear of their hats. This so-called "back badge" is unique in the British Army and was awarded to the 28th Regiment of Foot for their actions at the Battle of Alexandria in 1801. Knowledge of that battle honour, represented by the back badge, is said to have encouraged the soldiers of the Gloucestershire Regiment in the defence of Gloster Hill during the Battle of the Imjin River in April 1951 during the Korean War.
