In this episode of Stuff You Should Know, the hosts explore a World War II British intelligence operation that used a corpse to deceive Nazi forces. The operation, conceived by Ian Fleming and Admiral John Godfrey, involved planting false invasion plans on a deceased Welsh man who was given an elaborate fake identity as "Major Martin" and transported by submarine to the Spanish coast.
The summary details how British intelligence officers created an intricate backstory for the corpse, complete with personal effects and worn clothing. Their meticulous planning paid off when the planted documents made their way to Hitler himself, successfully convincing Nazi forces to move 90,000 troops away from Sicily—the Allies' actual invasion target—and reducing Allied casualties by an estimated 3,000 soldiers in the initial days of fighting.

Operation Mincemeat, a creative British intelligence operation during World War II, began with a unique proposal. Ian Fleming, who would later create James Bond, co-authored the Trout Memo with Admiral John Godfrey, suggesting the use of a corpse dressed as an airman to deceive enemy forces about invasion plans.
The operation was led by the "Xx Committee," headed by Ewan Montague and Charles Cholmondeley. They found their subject in Glyndwr Michael, a deceased Welshman, and meticulously crafted a false identity complete with personal effects and backstory. The committee's dedication to authenticity went as far as having members engage in elaborate role-playing, including writing love letters and wearing the deceased's uniform to create wear patterns.
The operation centered on transporting Michael's body, now known as Major Martin, to Spain by submarine. After releasing the body near the Spanish port of Huelva, British authorities sent telegrams about a "missing" officer to draw attention to the planted documents. Spanish authorities recovered the body and briefcase, which eventually made its way through Nazi hands to Hitler himself, thanks to Adolf Clauss's involvement.
Josh Clark notes that the operation successfully deceived the Nazis into believing the Allies would attack Greece rather than Sicily. As Chuck Bryant points out, this deception played into Hitler's existing concerns, leading him to move an entire Panzer division of 90,000 troops from Sicily to Greece. This strategic misdirection proved invaluable during the Allied invasion of Sicily, with historians estimating it reduced Allied casualties from an expected 10,000 to approximately 7,000 in the first three days of fighting.
1-Page Summary
Operation Mincemeat was a daring and creative British intelligence operation during World War II, designed to mislead the Axis powers about Allied invasion plans.
In the early stages of planning, the involvement of Ian Fleming and the Trout Memo set the stage for what would become a unique chapter in espionage history.
The Trout Memo, distributed by Admiral John Godfrey of British naval intelligence, was co-authored by his assistant, Lieutenant Commander Ian Fleming, who would later create James Bond. This document outlined 51 operations, but number 28 captured the imagination with its bold suggestion: dressing up a corpse as an airman carrying fraudulent dispatches to suggest a fake invasion of Greece, when in reality, the target was Sicily. The corpse, seemingly a casualty of a failed parachute landing, would serve as a tool to deceive the enemy.
Ewan Montague and Charles Cholmondeley, leading the Xx Committee, were tasked with bringing Fleming's outline to life, which required creativity, legal leeway, and moral flexibility.
Montague and Cholmondeley meticulously crafted a backstory and false persona for the operation. They were granted free rein to navigate legal and moral boundaries as needed, ensuring that only those who needed to know were informed. The identity they created was supported by detailed wallet contents, including theater ticket stubs and a bank overdraft letter, adding authenticity to the deceptive narrative.
Finding a suitable corpse was complex, but Glyndwr Michael, a tragic Welshman who died from ingesting rat poison, fit the bill. Born to a coal miner, Michael's life was marked by depression, poverty, and personal loss, culminating in his unclear death — whether suicide or a desperate accident remained a mystery. The circumstances made his body available for the operation, discov ...
The Planning and Development of Operation Mincemeat
The execution of Operation Mincemeat was meticulous and relied heavily on deception, as planners sought to misdirect Nazi forces by using the body of Glyndwr Michael, named Major William Martin for the ruse.
Glyndwr Michael's body, known for the operation as Major Martin, was transported to Spain in a specially designed metal cylinder, which the crew aboard the submarine believed to contain a weather buoy. The sub commander was privy to the cylinder's true contents. The body was released from the canister into the sea off the coast of Huelva, Spain. The operation aimed to fool the Nazis into deploying their troops incorrectly, helped by Spain's Axis sympathies and connections to Nazi Germany.
British authorities fabricated urgency through telegrams to their council in Spain about a missing important person, emphasizing the need to find Major Martin's briefcase. This detail was crucial for convincing Spanish authorities, and subsequently Nazi Germany, of the fake invasion plans contained within the briefcase.
The body was carried by the current directly to Huelva, where a fisherman found it the same day. Spanish authorities, seeing the body as an important find, recovered Major Martin and the briefcase with its contents.
The Spanish agreed not to conduct a full autops ...
The Execution of the Operation
The significance of Operation Mincemeat cannot be overstated; it was a masterful act of deception that had far-reaching impacts on the course of World War II, particularly during the Allies' invasion of Sicily.
The Allies deceived the Nazis into believing that they planned to invade Greece, not Sicily, using a letter planted on a corpse dressed as an officer. This letter, which appeared to be a personal, non-official communication between high-ranking officials, hinted at the false plans and was crucial in misinforming the enemy. Josh Clark notes the cleverness of the misinformation contained in the false letter, which suggested that Sicily was just a diversion.
The false information proved to be very effective, as Chuck Bryant points out that it played into Hitler's preexisting concerns about a Sicilian invasion. Consequently, Hitler moved an entire Panzer division, counting approximately 90,000 troops, along with artillery and armaments from Sicily to Greece. This significant reallocation of Axis defenses drastically weakened their strategic position in Sicily.
The influence of Operation Mincemeat on the actual invasion resulted in a markedly positive outcome for the Allies.
Historians and military assessments believe that Operation Mincemeat played a critical role in reducing allied casualties. Instead of the expected 10,00 ...
