Fourth Army (United Kingdom) - Second World War

Second World War

In World War II, no British Fourth Army actually took the field, but as part of the deception plans Operation Cockade and the later Operation Fortitude North, the Germans were encouraged to believe that a Fourth Army had been established with its headquarters in Edinburgh Castle, and was preparing to invade Norway. This successfully drew and kept German units away from the real invasion zone in Normandy. In the subsequent 'Fortitude South' the Fourth Army with different units was presented as part of the fictitious First United States Army Group (FUSAG) in its threat to the Pas de Calais.
