A British Twelfth Army was initially invented by 'A' Force as part as the deception plan for Operation Husky, the Allied invasion of Sicily in July 1943.
[1] The deception plan attempted to convince the Germans that this army had twelve divisions under its control and was located in Egypt.
[1][2] The army's formation insignia was a trained seal balancing on its nose a terrestrial globe showing the Eastern Hemisphere, black on a white background.
[4] Between 1943 and 1945, when it was disbanded to allow the formation of the second British Twelfth Army, its nominal existence was used to create the impression of a standing threat to the Balkans.
The formation insignia was a Chinthe on a red background, with a superimposed horizontal black stripe on which was written "XII" in white letters.
