Churchill's Underground Army: A History of the Auxillary Units in World War II

A carefully researched book on a long-neglected subject which fills a major gap in our Second World War knowledge Norman Longmate, author of If Britain Had Fallen

British Secret Intelligence Service officers and others in the War Office were never convinced that appeasement would prevent a Nazi invasion. Defying high-level opposition, they quietly worked instead on preemptive Last Ditch survival plans. These included a secret resistance network known as the GHQ Auxiliary Units. It was the only one in Europe prepared in advance of an enemy assault.

The Auxunits were civilian stay-behinds . One section worked as Patrols, usually consisting of half-a-dozen men in hidden underground operational bases. They were hurriedly selected immediately after the Dunkirk evacuation then trained and equipped with firearms, explosives and booby-traps. Instructed to stay-behind underground as the enemy passed over, they were then to emerge each night to commit mayhem for as long as they could stay alive. Others, men and women, would remain behind above ground, to spy on the enemy and communicate intelligence to the Defense Force by a covert radio network. These Units are still effectively secret and this is the most comprehensive history published to date.
