Operation Cascade gave the Allies valuable experience in planning deception operations, which was later used to good effect in the deception operations covering the invasion of Europe (D-Day landings in Normandy, and the invasion of Southern France). The British forces built up during Operation Cascade were later used in Operation Zeppelin to tie down Axis forces in the Balkans and Greece, and deter the Axis from using these forces against the Allied invasion of Sicily, (Operation Husky). In 1944, the actual Allied strength in the Mediterranean totalled about 52 divisions; Axis intelligence accepted a strength of about 70 divisions in the theatre.
