Auxiliary WW2 The Boldon's

The Auxiliary Units or GHQ Auxiliary Units were specially trained, highly secret units created by the United Kingdom government during the Second World War, with the aim using irregular warfare to help combat any invasion of the United Kingdom by Nazi Germany, which the Germans codenamed Operation Sea Lion. Urged on by the War Office, Prime Minister Winston Churchill initiated the Auxiliary Units in the early summer of 1940. This was to counter the civilian Home Defence Scheme already established by SIS (MI6), but outside War Office control. The Auxiliary Units answered to GHQ Home Forces, but were organised as if part of the local Home Guard.
