Operation Torch (8–16 November 1942) was the Anglo–American invasion of French North Africa during the Second World War. It was aimed at reducing pressure on Allied forces in Egypt, and enabling an invasion of Southern Europe. It also provided the ‘second front’ which the Soviet Union had been requesting since it was invaded by the Germans in 1941. The region was dominated by the Vichy French, officially in collaboration with Germany, but with mixed loyalties, and reports indicated that they might support the Allied initiative. The American General Dwight D. Eisenhower, commanding the operation, planned a three-pronged attack, aimed at Casablanca (Western), Oran (Center) and Algiers (Eastern), in advance of a rapid move on Tunis.
Operation Chastise was an attack on German dams carried out on 16–17 May 1943 by Royal Air Force No. 617 Squadron, later called the Dam Busters, using a purpose-built "bouncing bomb" developed by Barnes Wallis.
