Operation Mincemeat
Operation Mincemeat was a successful British deception operation of the Second World War to disguise the 1943 Allied invasion of Sicily. Two members of British intelligence obtained the body of Glyndwr Michael, a tramp who died from eating rat poison, dressed him as an officer of the Royal Marines and placed personal items on him identifying him as the fictitious Captain William Martin. Correspondence between two British generals that 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.
Part of the wider Operation Barclay, Mincemeat was based on the 1939 Trout memo, written by Rear Admiral John Godfrey, the director of the Naval Intelligence Division, and his personal assistant, Lieutenant Commander Ian Fleming. With the approval of the British prime minister, Winston Churchill, and the American military commander in the Mediterranean, General Dwight D. Eisenhower, the plan began by transporting the body to the southern coast of Spain by submarine and releasing it close to shore, where it was picked up the following morning by a Spanish fisherman. The nominally neutral Spanish government shared copies of the documents with the Abwehr, the German military intelligence organisation, before returning the originals to the British. Forensic examination showed they had been read and Ultra decrypts of German messages showed that the Germans fell for the ruse. German reinforcements were shifted to Greece and Sardinia before and during the invasion of Sicily; Sicily received none.
The full effect of Operation Mincemeat is not known, but Sicily was liberated more quickly than anticipated and losses were lower than predicted. The events were depicted in Operation Heartbreak, a 1950 novel by the former cabinet minister Duff Cooper, before one of the intelligence officers who planned and carried out Mincemeat, Ewen Montagu, wrote a history in 1953. Montagu's book formed the basis for the 1956 British film The Man Who Never Was. A second British film was released in 2021, titled Operation Mincemeat. It also has been adapted into a musical.
Background
Inspiration for Mincemeat
On 29 September 1939, soon after the start of the Second World War, Rear Admiral John Godfrey, the Director of Naval Intelligence, circulated the Trout memo, a paper that compared the deception of an enemy in wartime to fly fishing. The journalist and author Ben Macintyre observes that although the paper was published under Godfrey's name, it "bore all the hallmarks of ... Lieutenant Commander Ian Fleming", Godfrey's personal assistant. The memo contained a number of schemes to be considered for use against the Axis powers to lure U-boats and German surface ships towards minefields. Number 28 on the list was titled: "A Suggestion "; it was an idea to plant misleading papers on a corpse that would be found by the enemy.The deliberate planting of fake documents to be found by the enemy was not new; known as the Haversack Ruse, it had been practised by the British and others in the First and Second World Wars. In August 1942, before the Battle of Alam el Halfa, a corpse was placed in a blown-up scout car, in a minefield facing the German 90th Light Division. On the corpse was a map purportedly showing the locations of British minefields; the Germans used the map, and their tanks were routed to areas of soft sand where they bogged down.
In September 1942 an aircraft flying from Britain to Gibraltar crashed off Cádiz. All aboard were killed, including Paymaster-Lieutenant James Hadden Turner – a courier carrying top secret documents – and a French agent. Turner's documents included a letter from General Mark Clark, the American deputy commander of the Allied Expeditionary Force, to General Noel Mason-MacFarlane, British governor and commander in chief of Gibraltar, informing him that General Dwight D. Eisenhower, the Supreme Commander, would arrive in Gibraltar on the eve of Operation Torch's "target date" of 4November. Turner's body washed up on the beach near Tarifa and was recovered by the Spanish authorities. When the body was returned to the British, the letter was still on it, and technicians determined that the letter had not been opened. Other Allied intelligence sources established that the notebook carried by the French agent had been copied by the Germans, but they dismissed it as being disinformation. To British planners, it showed that some material that was obtained by the Spanish was being passed to the Germans.
British Intelligence and the inspiration for the plan
A month after the Turner crash, the British intelligence officer Charles Cholmondeley outlined his own variation of the Trout memo plan, codenamed Trojan Horse, after the Achaean deception from the Trojan War. His plan was:Cholmondeley was a flight lieutenant in the Royal Air Force who had been seconded to MI5, Britain's domestic counter-intelligence and security service. He had been appointed as the secretary of the Twenty Committee, a small inter-service, inter-departmental intelligence team in charge of double agents. In November 1942 the Twenty Committee turned down Cholmondeley's plan as being unworkable, but thought there may have been some potential in the idea. As there was a naval connection to the plan, John Masterman, the chairman of the committee, assigned Ewen Montagu, the naval representative, to work with Cholmondeley to develop the plan further. Montagu – a peacetime lawyer and King's Counsel who had volunteered at the outbreak of the war – worked under Godfrey at the Naval Intelligence Division, where he ran NID 17, the sub-branch which handled counter-espionage work. Godfrey had also appointed Montagu to oversee all naval deception involving double agents. As part of his duties, Montagu had been briefed on the need for deception operations to aid the Allied war aims in a forthcoming invasion operation in the Mediterranean.
Military situation
In late 1942, with the Allied success in the North African campaign, military planners turned their attention to the next target. British planners considered that an invasion of France from Britain could not take place until 1944 and the prime minister, Winston Churchill, wanted to use the Allied forces from North Africa to attack Europe's "soft underbelly". There were two possible targets for the Allies to attack. The first option was Sicily; control of the island would open the Mediterranean Sea to Allied shipping and allow the invasion of continental Europe through Italy. The second option was to go into Greece and the Balkans, to trap the German forces between the British and American invaders and the Soviets. At the Casablanca Conference in January 1943, Allied planners agreed on the selection of Sicily – codenamed Operation Husky – and decided to undertake the invasion no later than July. There was concern among the Allied planners that Sicily was an obvious choice – Churchill is reputed to have said "Everyone but a bloody fool would know that it's Sicily" – and that the build-up of resources for the invasion would be detected.Adolf Hitler was concerned about a Balkan invasion, as the area had been the source of raw materials for the German war industry, including copper, bauxite, chrome and oil. The Allies knew of Hitler's fears, and they launched Operation Barclay, a deception operation to play upon his concerns and to mislead the Germans into thinking the Balkans were the objective, diverting resources from Sicily. The deception reinforced German strategic thinking about the likely British target. To suggest the eastern Mediterranean was the target, the Allies set up a headquarters in Cairo, Egypt, for a fictional formation, the Twelfth Army, consisting of twelve divisions. Military manoeuvres were conducted in Syria, with numbers inflated by dummy tanks and armoured vehicles to deceive observers. Greek interpreters were recruited and the Allies stockpiled Greek maps and currency. False communications about troop movements were generated from the Twelfth Army headquarters, while the Allied command post in Tunis – which was to be the headquarters of the Sicily invasion – reduced radio traffic by using landlines wherever possible.
Development
Examining the practicalities; locating a corpse
Montagu and Cholmondeley were assisted by an MI6 representative, Major Frank Foley, as they examined the practicalities of the plan. Montagu approached the pathologist Sir Bernard Spilsbury to determine what kind of body they needed and what factors they would need to take into account to fool a Spanish pathologist. Spilsbury informed him that those who died in an air crash often did so from shock and not drowning; the lungs would not necessarily be filled with water. He added that "Spaniards, as Roman Catholics, were averse to post-mortems and did not hold them unless the cause of death was of great importance". Spilsbury advised that a person could have suffered one of many different causes of death, which could be misconstrued in an autopsy. Montagu later wroteThis meant that not only would they have a better degree of success than they previously thought, but that there would be a larger number of corpses potentially available for selection when the time came. When Montagu discussed the possibility of obtaining a corpse with Bentley Purchase, the coroner for the Northern District of London, he was told there would be practical and legal difficulties: "I should think bodies are the only commodities not in short supply at the moment even with bodies all over the place, each one has to be accounted for". Purchase promised to look out for a body that was suitable, with no relatives who would claim the corpse for burial.
On 28 January 1943 Purchase contacted Montagu with the news he had located a suitable body, probably that of Glyndwr Michael, a tramp who died from eating rat poison that contained phosphorus. Purchase informed Montagu and Cholmondeley that the small amount of poison in the system would not be identified in a body that was supposed to have been floating in the sea for several days. When Montagu commented that the under-nourished corpse did not look like a fit field officer, Purchase informed him that "he does not have to look like an officer – only a staff officer", more used to office work. Purchase agreed to keep the body in the mortuary refrigerator at a temperature of – any colder and the flesh would freeze, which would be obvious after the body defrosted. He warned Montagu and Cholmondeley that the body had to be used within three months, after which it would have decomposed past the point of usefulness.
