A Life in the Pockets

The Hook and the Corpse

Mara: London, 1943. In a basement room under the naval headquarters, Ewen Montagu, a Lieutenant Commander in the Royal Naval Volunteer Reserve, runs a small team called Section 17M. His problem is that everyone can read the map. Winston Churchill put it bluntly: “Anyone but a bloody fool would know it was Sicily.”

Eli: Eisenhower's commanders agreed: if German troops got there first, success was “practically nil.”

Mara: So Montagu revives an old and grisly idea. A corpse.

Eli: The listener asked: what was Operation Mincemeat, the plan to fool Hitler with a dead man carrying fake secret papers? Today's angle is what Operation Mincemeat was.

Mara: It's a story that runs from a London mortuary to a submarine, a Spanish beach and a briefcase that changes hands in secret. And one thing stays open almost to the end: whether anyone on the German side would believe it.

Eli: And the idea is older than Montagu's part in it. In 1939 Ian Fleming, then in naval intelligence under an admiral, drafted the Trout Memo, a list of ways to fool an enemy, pictured as fly-fishing. “The Trout Fisher casts patiently all day. He frequently changes his venue and his lures.” Historian Ben Macintyre says idea number 28 was the kernel: make a dead body look like a drowned airman, give it false papers, ship it somewhere. Fleming took it from a novel.

Mara: So Montagu inherits a lure on paper, and making it real takes a body. In January 1943, at St Stephen's Hospital on the Fulham Road, a thirty-four-year-old Welsh labourer of no fixed abode, Glyndwr Michael, dies two days after swallowing rat poison containing phosphorus. Historian Denis Smyth concluded, from a secret memo of Montagu's, that this was the man used, though that identity is still disputed. The coroner, Bentley Purchase, makes sure there's no post-mortem, and above all no autopsy, nothing that might leave traces for a foreign investigation.

Eli: And the poison matters. Phosphorus in the stomach makes a toxic gas that fills the lungs with liquid. Which is roughly what a drowned man's lungs look like.

Mara: Montagu reasoned that a doctor who already expected a drowning would hardly notice the difference from sea water, in lungs that had started to decompose. Purchase counted on that same decay to mask the poison.

Eli: So the lungs could pass for a drowning, Mara. What Montagu doesn't have yet is a man anyone would believe in.

Inventing Major Martin

Mara: A body isn't a person yet. The real test is whether a life made of paper can fool German intelligence.

Eli: Montagu and his partner Charles Cholmondeley knew a bare document would fail. Montagu wrote that Pooh-Bah was right about “corroborative detail, intended to give artistic verisimilitude to an otherwise bald and unconvincing narrative.” Verisimilitude: the look of truth that small, ordinary details give a story. So they built a man. William Martin, Royal Marines, a captain serving as acting major, born in Cardiff in 1907, posted to Combined Operations Headquarters.

Mara: Then comes the identity card. They tried photographing the corpse.

Eli: And it showed. Every photo clearly depicted a dead man. So an MI5 officer with similar features sat for the picture instead, and since a new card looked wrong for a major, it was marked as a replacement for a lost one. Then a silver cross and a St Christopher medallion, to say Catholic. The pathologist advising them held that “Spaniards, as Roman Catholics, were averse to post-mortems and did not hold them unless the cause of death was of great importance.”

Mara: Then the pocket litter, the everyday clutter that says someone actually lived. Hester Leggatt wrote his fiancée's love letters. One opens “Bill darling,” and asks “why did we go and meet in the middle of a war?” The fiancée, Pam, got a face: a photograph of Jean Leslie, an MI5 secretary. And there's a receipt for an engagement ring.

Eli: And the dull paperwork. Montagu's team made Martin a little careless: unpaid bills, an expired headquarters pass, an angry letter from his bank. Jean Leslie recalled the evenings that fed it. “He was Willie, I was Pam,” she said. “We went to clubs, films and dinner - always keeping ticket stubs.” British intelligence believed that kind of mundane mess, right down to the stubs, was what would persuade Axis examiners.

Mara: And Montagu did the ageing himself. The cards were fresh replacements, too new for a long-serving officer, so the Lieutenant Commander spent weeks rubbing them on his trousers for a used sheen. Not every naval officer's war was fought at the knee.

Eli: Martin is finished, down to the shine on his cards. Whether anyone senior will let him go to sea is another matter.

The Canister and the Cabinet

Mara: By April the clock is loud. Back in February, Montagu and Cholmondeley had told the Twenty Committee the body would have to be “used within the next three months or so”. Colonel Bevan took the plan to Churchill and warned that “the body might never get washed up,” or that the Spaniards might hand it back without taking the papers. Churchill answered: “Well, in that case we shall have to get the body back and give it another swim.” He authorized it, and Eisenhower approved it too.

Eli: Dry. But papers handed back unread would mean the whole thing failed quietly.

Mara: Nobody, not even Montagu, knows yet whether a German will ever read his letters.

Eli: Then the dressing. In the early hours of 17 April 1943, Purchase, Montagu and Cholmondeley couldn't get the boots on. The feet had frozen. They found an electric heater. Then into a dry-ice canister: a sealed sheet-steel box lined with asbestos wool, packed with frozen carbon dioxide to stop the decay. About 400 pounds loaded, labelled optical instruments. In Montagu's words: “In an airtight container full of carbon dioxide so he didn't rot.” A borrowed War Office van took it north to Scotland.

Mara: A dead Welshman, travelling as a major, labelled as optics.

Eli: Now everything rides on a submarine putting him in exactly the right stretch of Spanish sea.

A Drop in the Dark

Mara: April 30th, 1943, off Huelva in Spain. Out of the canister and over the side of HMS Seraph comes Major Martin. The submarine's commander recites what he can remember of the burial service as his officers bow their heads. At exactly four-thirty in the morning they lower the body into the sea, and his life-jacket keeps him afloat about a mile from the beach. The story is a plane crash at sea on the way to North Africa, because the Germans knew the Allies never sent secret papers on flights over enemy territory.

Eli: Huelva was picked for its German agents, very active and very well connected.

Mara: And the tide does its part. At seven-thirty a fisherman from Punta Umbria finds the body on El Portil beach, brings it to the port and tells the Spanish authorities.

Eli: Next comes the part that could sink everything: a post-mortem. That silver cross was there because of a pathologist's belief that Catholic Spain disliked them. The examination in Huelva stayed short. One account says a British official in on the plot persuaded the Spanish doctors to take an early lunch.

Mara: So the poisoned lungs Purchase counted on never got a careful look.

Eli: Then London plays it loud. The Admiralty sends urgent messages to the naval attaché in Madrid, wanting the papers back “at any cost”. That's bait, meant to tell the Spanish how important the briefcase is. And it reaches the Abwehr, German military intelligence, which had agents all over neutral Spain. The local Abwehr man gets hold of the documents, not without difficulty. The Germans open the briefcase carefully and photograph everything. Then the Spanish hand it back to the British.

Mara: Back in London, Montagu has Martin's name put on the British casualty list in The Times, knowing the Germans read it to check him. The letters are on German film now, Eli. What Berlin makes of them is another thing entirely.

Swallowed Whole

Eli: German high command, May 1943. The papers reach the top, and they meet a disagreement. A German admiral recorded that the Führer did not agree with his Italian ally that Sicily was the likeliest invasion point. On May 18th Hitler briefly wonders whether the body is a plant. General Alfred Jodl, head of the operations staff, dismisses it. As he's quoted: “You can forget about Sicily. We know it's in Greece.”

Mara: So Churchill's line flips. The leader who said Sicily got overruled.

Eli: And London could watch. On Christmas Day 1941, Bletchley Park produced its first complete decrypt of an Abwehr Enigma message, the first of a long series. Those are the Ultra decrypts. Through them the British follow the planted story up the German chain.

Mara: So the British were reading the enemy's own mail about their dead man.

Eli: That's it, and the mail says yes. British intelligence tells Churchill that Mincemeat has been swallowed whole. Then come the moves. Patrol ships, minelayers and minesweepers meant to defend Sicily go elsewhere. By one disputed count, German divisions in the Balkans rise from eight to eighteen. And Montagu said Hitler still believed the papers on July 23rd, when he named Rommel commander-in-chief of a reinforced Greece.

Mara: So the man Montagu built from ticket stubs and overdrafts passed inspection.

Eli: Though who was inside the uniform?

Mara: Isobel Mackay was three when her father, Royal Navy sailor John Melville, died. His ship, HMS Dasher, sank on March 27th, 1943. In 2004, sixty-one years later, she told The Scotsman: “I feel very honoured if my father saved 30,000 Allied lives.” In 2022 Admiral Lord West argued the body may have been Melville's, because by then Glyndwr Michael's was too deteriorated.

Eli: The official record still names Glyndwr Michael.

Mara: In Huelva the body was buried as William Martin, in a tranquil spot looking down over the port where he was found. Decades after the war, an inscription honouring Glyndwr Michael was added. Denis Smyth says: “I think I've demolished what they think is the case for the counter-argument.” The Commonwealth War Graves Commission says casualties could have been many more without Michael's posthumous service.

Eli: Which brings back the island. Ewen Montagu, Sir Michael Howard and Ben Macintyre are among those who read Mincemeat as decisive. They point to the result: a campaign planned for ninety days, over in thirty-eight, with casualties and ship losses far below what was expected.

Mara: Others, Sir David Hunt among them, read it as secondary: it confirmed what the Germans already suspected, and Sicily was decided mainly by Allied naval, air and ground superiority. One historian put the doubt this way: “It may be just a good story that exaggerates the importance of the deception, as intelligence operatives and officers invariably do.” Settling it, that historian added, would take research in the military intelligence files.

Eli: So that's Mincemeat: a British deception that turned one dead man into Major William Martin and set him adrift off Spain, carrying papers that pointed at Greece and Sardinia, not Sicily. Montagu argued it moved Hitler's forces away from the island. How much that decided the battle is still argued.

Mara: Back in that basement, Montagu was betting a believable enough man could beat a map everyone could read. Two things to watch now. Whether anyone ever runs forensic or genetic tests on the grave in Huelva, to settle Michael or Melville. And whether historians ever agree how much of the invasion's success belongs to the deception, and how much to Allied strength.

Eli: Look up Trout Memo.

Mara: And stay with us on security.

Eli: Thanks for listening. I'm Eli.

Mara: And I'm Mara. Until next time.
