In 1940 a group of artists, sculptors, film makers, theatre designers and set painters came together to form the Camouflage Unit. Led by Major Geoffrey Barkas and including the internationally renowned magician Jasper Maskelyne, the unit’s projects became a crucial battlefield weapon, most famously at El Alamein where they made 600 tanks seem to disappear and reappear fifty miles away. Rick Stroud (The Phantom Army of Alamein) tells the amazing story of how the stage effects of some of Britain’s most creative men played a vital role in winning the war.
