German belief in an amphibious invasion of the Eastern Mediterranean.
During World War II, Operation Zeppelin was a deception plan carried out by the Allies designed to depict a potential amphibious landing on Crete, western Greece, or the RomanianBlack Sea coast. It was carried out in the time preceding the invasion of Normandy.
Zeppelin was a sub-plan of Operation Bodyguard, a broad strategic deception in support of the Allied landings in Normandy. Zeppelin formed only a small part of the overall plan (the bulk of which comprised Operation Fortitude). During early 1944, the Allies attempted to threaten invasions along the whole coast of Europe, from Norway through France and to the Mediterranean.
Planning for Zeppelin involved collaboration between British, American and Russian. According to the deception's storyline, Allied planners from Britain, America and Russia identified several potential landing sites before, in February 1944, settling on Crete and parts of Croatia with an invasion date of March 29 (picked because it was a full moon).
