The Victoria Cross (VC) was first awarded in 1856. It is the highest military award that can be bestowed and is for valour in the face of the enemy. It is now rarely awarded and is usually posthumous - the only exception since the Korean War being Private Johnson Beharry who was nursed back to health in Selly Oak Hospital.
The George Cross (GC) was intended as the "civilian" equivalent of the Victoria Cross. It was introduced in 1940 and replaced the Empire Gallantry Medal and then later the Albert and Edward Medals. Holders of these superseded awards were invited to swap their awards for the George Cross. It too is now rarely awarded and usually now goes to the police or the armed forces operating not in the face of the enemy.
