The claim that Dieppe made the Normandy landings possible is challenged on the grounds that relevant lessons had already emerged in Norway. Those lessons were already being applied before Dieppe. Mountbatten's Combined Operations organisation, responsible for commando missions, was separate from Ramsay's staff planning D-Day. In this interpretation, Mountbatten wanted a larger planning role, but Ramsay retained control.
