Question: The Man Who Never Was is a 1956 Second World War film, based on the book of the same name by Lt. Cmdr. Ewen Montagu and dramatising actual events, it is about which 1943 British Intelligence plan to deceive the Axis powers into thinking Operation "Husky", the Allied invasion of Sicily, would take place elsewhere, a successful British disinformation strategy?
Context: Operation Fustian was an airborne forces operation undertaken during the Allied invasion of Sicily in July 1943 in the Second World War.  The operation was carried out by Brigadier Gerald Lathbury's 1st Parachute Brigade, part of the British 1st Airborne Division.  Their objective was the Primosole Bridge across the Simeto River.  The intention was for the brigade, with glider-borne forces in support, to land on both sides of the river.  They would then capture the bridge and secure the surrounding area until relieved by the advance of British XIII Corps, which had landed on the south eastern coast three days previously.  Because the bridge was the only crossing on the river and would give the British Eighth Army access to the Catania plain, its capture was expected to speed the advance and lead to the defeat of the Axis forces in Sicily. Operation "Ladbroke" was a glider landing by British airborne troops during the Second World War near Syracuse, Sicily, that began on 9 July 1943 as part of Operation Husky, the Allied invasion of Sicily.  The first Allied mission using large numbers of the aircraft, the operation was carried out from Tunisia by glider infantry of the British 1st Airlanding Brigade, commanded by Brigadier Philip Hicks, with a force of 136 Waco Hadrians and eight Airspeed Horsas.  The objective was to establish a large invasion force on the ground near the town of Syracuse, secure the Ponte Grande Bridge and ultimately take control of the city itself with its strategically vital docks, as a prelude to the full-scale invasion of Sicily. Operation Animals was a World War II mission by the British Special Operations Executive (SOE), in cooperation with the Greek Resistance groups ELAS, Zeus, PAO and the United States Air Force.  The operation took place between 21 June and 11 July 1943 and included an organized campaign of sabotage in Greece, to deceive the Axis Powers into believing that Greece was the target of an Allied amphibious landing, instead of Sicily.  Despite the mission's success, the Greek civilian population suffered from mass reprisals and British intervention into the internal affairs of the Greek resistance exacerbated the tensions between its various components. Thomas Argyll Robertson {'1': ", '2': ", '3': ", '4': "} (27 October 1909 – 10 May 1994), known as "Tommy" or by his initials as "TAR", was a Scottish MI5 intelligence officer responsible during the Second World War for the "Double-Cross" ("XX") disinformation campaign against the German intelligence services.  Every German agent in Britain, with the exception of one who committed suicide without having been detected by the authorities, was actually working for British intelligence .  Included in this was Operation Mincemeat.  The disinformation campaign was successful in persuading the Germans that the invasions of Sicily (1943) and Normandy (1944) were going to occur elsewhere. Captain Ewen Edward Samuel Montagu, CBE, QC, DL, RNR (19 March 1901 – 19 July 1985) was a British judge, writer and Naval intelligence officer.  He is well known for his leading role in Operation Mincemeat, a critical military deception operation which misdirected German forces' attention away from the Allied Invasion of Sicily in Operation Husky. The Man Who Never Was is a 1956 Second World War film, based on the book of the same name by Lt. Cmdr. Ewen Montagu and dramatising actual events.  The film was directed by Ronald Neame and starred Clifton Webb, Gloria Grahame and Robert Flemyng.  It is about Operation "Mincemeat", a 1943 British Intelligence plan to deceive the Axis powers into thinking Operation "Husky", the Allied invasion of Sicily, would take place elsewhere. The Man Who Never Was is a 1953 book by Ewen Montagu about the World War II Operation Mincemeat.  Montagu played a leading role in the 1943 scheme to deceive the Germans about the planned Allied invasion of Sicily.  Montagu's work formed the basis for a 1956 film by the same title.  The scheme entailed releasing a dead body just off the coast of Spain, where strong currents caused it to drift ashore in an area where a skilled German secret agent was known to operate.  The corpse was to appear to be the victim of an airplane crash, the non-existent Royal Marine Major William Martin, who had letters in a briefcase that hint at a forthcoming Allied invasion of Greece and Sardinia, rather than the obvious target of Sicily. Operation Corkscrew was the code name for the Allied invasion of the Italian island of Pantelleria (between Sicily and Tunisia) on 11 June 1943, prior to the Allied invasion of Sicily during the Second World War.  There had been an early plan to occupy the island in late 1940 (Operation Workshop), but this was aborted when the Luftwaffe strengthened the Axis air threat in the region. Operation Mincemeat was a successful British disinformation strategy used during the Second World War.  As a deception intended to cover the 1943 Allied invasion of Sicily, two members of British intelligence obtained the body of Glyndwr Michael, a homeless man who died from eating rat poison, dressed him as an officer of the Royal Marines and placed personal items on him identifying him as Captain (Acting Major) William Martin.  Correspondence between two British generals which suggested that the Allies planned to invade Greece and Sardinia, with Sicily as merely the target of a feint, was also placed on the body. The Allied invasion of Sicily, codenamed Operation Husky, was a major campaign of World War II, in which the Allies took the island of Sicily from the Axis powers (Italy and Nazi Germany).  It was a large amphibious and airborne operation, followed by a six-week land campaign and was the beginning of the Italian Campaign.
