In this episode we offer an extensive overview of the Dieppe Raid (Operation Jubilee) of August 1942, detailing this disastrous Allied amphibious attack on German-occupied France during World War II. We outline the raid's background, including the strategic reasons like placating the Soviet Union and testing invasion tactics, and the involvement of key figures such as Louis Mountbatten. The bulk of the episode focuses on the battle itself, describing the landings on various beaches, the heavy casualties suffered by the predominantly Canadian forces, and the resulting German victory. Finally, we discuss the aftermath, emphasizing the critical lessons learned that influenced the later D-Day landings, the high casualty rates on both sides, and the German use of the failure for propaganda purposes.
