Osprey's examination of the Dieppe raid of August 1942, which was one of the most controversial actions of World War II (1939-1945). Operation 'Jubilee' was a frontal assault on a fortified port landing the latest equipment and armour directly on to the beach. The main force would destroy the port facilities while other smaller landings dealt with anti-aircraft and coastal batteries. The raid itself turned into a fiasco. The assault force was pinned down on the beach and three quartersof the 5,000 troops landed were lost. This book analyses the disastrous raid and examines contrasting conclusions drawn by the Allies and the Germans.
