The invasion fleet sailed into worsening weather. In Malta, Admiral Cunningham and Lord Mountbatten privately expressed pessimism as gale-force winds battered the ships, causing widespread seasickness. Major Derrick Leverton of the Twelfth Light Anti-Aircraft Regiment remained cheerful, playing bridge and eating chocolate. As the wind dropped near sunset, he watched Allied bombers and gliders pass overhead, feeling oddly detached, as if watching a play.

At the same time, Jewell surfaced the Seraph. The E-boat had vanished, and just after midnight, the crew successfully dropped the homing beacon. Shore-based searchlights illuminated the submarine, and Italian guns opened fire. For 10 minutes, the Seraph sat immobile as shells exploded around her, but Jewell’s orders were to stay put. When the lead destroyer appeared, its American crew cheered the submarine that had held position. A captain delivered the admiral’s thanks, and the Seraph withdrew into darkness.

Colonel Bill Darby stormed the beach at Gela, leading from the front. Patton later awarded him the Distinguished Service Cross. Major Leverton napped on deck while the battle raged, then waded ashore at dawn past wrecked gliders and dead paratroopers, noticing the smell of crushed thyme. While his men unloaded guns, he made tea. Dive-bombers attacked; a stone blasted from a nearby wall narrowly missed his head. Leverton ordered foxholes dug and went back to sleep. By nightfall, his guns had shot down one plane. Finding his uniform too hot, he designed a utility invasion suit of shirt, swimming shorts, and helmet.

Mussolini, woken at 6:00 am with news of the invasion, confidently ordered his troops to repel the attack. By day’s end, over 100,000 Allied troops were ashore as Italian defenses collapsed. Allied casualties were far lower than expected, though the airborne landings proved costly: Gliders crashed, paratroopers scattered, and friendly fire killed many in the second wave. Allied deceptions continued to protect the force, and German counterattacks were delayed. On July 11, the Hermann Göring division’s assault failed, with 43 tanks destroyed. Patton later called it the shortest Blitzkrieg in history. The Sicilian D-Day was won.

Room 13 erupted in cheers as news of the Sicily invasion broke. Cholmondeley danced; Montagu privately feared his wartime role was ending. He reflected on the satisfaction of saving Allied lives and fooling Hitler himself. Operation Mincemeat had cost approximately £200. His wife Iris returned from America with their children, the photograph of “Pam” gone from his dressing table. Congratulatory messages flooded in from Dudley Clarke, General Nye, and MI6 officer Frank Foley. Guy Liddell recorded the operation as an outstanding success. Johnnie Bevan recommended both Montagu and Cholmondeley for decorations, crediting Cholmondeley as the scheme’s originator. 

Mincemeat succeeded beyond expectations, though it reinforced existing German beliefs and benefited from Hitler’s doubts about Italy’s commitment. Ultra intercepts showed that even after the landings began, German planes flew from Sicily to Sardinia, and the Abwehr continued believing Sicily was a feint. German naval assets moved from Sicily to the Aegean to defend Greece. Rommel was dispatched to Salonika at the end of July to command Greek defenses.

German recriminations began immediately. Foreign Minister von Ribbentrop furiously demanded an investigation, convinced the documents were a British plant and suspecting Spanish complicity. German Ambassador Dieckhoff in Madrid weakly suggested the Allies had changed their plans. Von Ribbentrop demanded to know who was involved, placing Kühlenthal and Clauss in the firing line. Von Roenne, the secret anti-Nazi, protected the deception by issuing a report on July 26 claiming the Allies had merely given up their Greek attack.

The most significant casualty was Mussolini, whose authority collapsed. On July 25, the Fascist Grand Council deposed him, and Marshal Pietro Badoglio took power. Italy began secretly negotiating withdrawal from the war.

The invasion’s impact reached the Eastern Front. Postwar assessments confirmed that the deception letters influenced Hitler to move troops away from Sicily to other fronts before the invasion. After the landings, Hitler suspended Operation Citadel, the massive Kursk offensive, to divert troops to Italy. This cancellation marked a decisive turning point, as the Red Army launched a devastating counterattack and seized strategic initiative for the rest of the war. A telegram to Churchill captured the success, noting that Mincemeat had been swallowed “hook, line, and sinker” (285).

Even before the war ended, Ewen Montagu lobbied to reveal Operation Mincemeat. His 1945 request was denied due to concerns about Anglo-Spanish relations. In August 1944, radio journalist Sydney Moseley broadcasted a version of the story that closely resembled the truth, though he wrongly placed the deception before the Normandy landings. British intelligence decided to ignore the leak.

In 1949, former Cabinet minister Alfred Duff Cooper began a novel based on the story, likely learned from Churchill. His Operation Heartbreak, featuring a dead officer named William Maryngton used in deception, was published in November 1950 despite Whitehall pressure, causing consternation in security quarters. After this precedent, Montagu also demanded permission to publish. Initially ordered to return his Mincemeat files, Montagu refused and eventually received approval, but under strict vetting conditions.

Meanwhile, journalist Ian Colvin began investigating the true story after a footnote in Rommel’s published diaries linked Sicily to Cooper’s novel. Fearing Colvin would uncover embarrassing details, the Joint Intelligence Committee launched a spoiling operation. They ordered Montagu to publish immediately to preempt Colvin with an officially sanctioned version. The Sunday Express, which had commissioned Colvin, colluded in scooping their own journalist. Montagu contacted Jean Leslie and Bill Jewell to warn them. Jean worried about being identified as “Pam” but agreed to cooperate. Cholmondeley politely but firmly refused involvement or profits, citing his rather peculiar position.

The story was serialized in the Sunday Express in February 1953 as The Man Who Never Was. It became a huge bestseller, but opinion among his former colleagues was divided: Archie Nye and John Masterman criticized the publication, while Mountbatten gave qualified support. The book was a partial, controlled version presenting Montagu as the main hero while excising many participants. Cholmondeley appeared only fleetingly under a pseudonym. Montagu created a cover story about obtaining permission from Glyndwr Michael’s family on condition of anonymity, hiding the fact that his body was used without permission. The book’s success turned Montagu into a celebrity. A 1956 film adaptation starred Clifton Webb as Montagu and Gloria Grahame. Montagu made a cameo as an air vice marshal. Cholmondeley was an uncredited technical adviser, known only as “George.”

Three weeks after the Sicily invasion, Bill Jewell and Rosemary Galloway became engaged; they married in 1944. Lieutenant David Scott, an officer on the Seraph, rose to rear admiral. Derrick Leverton returned to his family's funeral business with his brother Ivor. Colonel Bill Darby was killed in Italy two days before the final German surrender. Alan Hillgarth continued in intelligence, becoming head of Naval Intelligence for the eastern theater against Japan, then a secret Cold War adviser to Churchill. Coroner Bentley Purchase was knighted and died in 1961.

Adolf Clauss was never punished due to his wife’s powerful family; he later claimed he knew Mincemeat was a trick all along. Wilhelm Leissner, the Abwehr chief in Madrid, congratulated British intelligence years later. Karl-Erich Kühlenthal escaped punishment. After the war, MI5 sent Juan Pujol (Agent Garbo)—who had been crucial to the D-Day deception and was awarded both the German Iron Cross and British MBE—to find him. Pujol tracked Kühlenthal to Ávila, where the former spymaster, still completely fooled, revealed Hitler personally ordered the Iron Cross for Garbo. MI5 concluded Kühlenthal posed no threat. He and his wife eventually returned to Germany, where he prospered in the textile business and became president of the Federal Association of German Textile Retailers, dying in 1975 without anyone questioning his past. Pujol moved to Venezuela and died in 1988.

Jean Leslie married soldier William Gerard Leigh, who had also fought in Sicily. Ewen Montagu’s brother, Ivor Montagu, continued communist activities and won the Lenin Peace Prize in 1959. Declassified Venona transcripts later revealed he was Soviet spy Agent Intelligentsia, but this was never made public in his lifetime. A 1944 Soviet NKVD report proved Moscow knew Mincemeat’s details.

Charles Cholmondeley joined the Middle East Anti-Locust Unit as cover while continuing secret-service work, later taking an RAF intelligence commission. He left MI5 in 1952, married Alison, started a business selling horticultural machinery, and never broke his vow of secrecy. Ewen Montagu praised him in an obituary letter after his death in 1982, noting many who landed in Sicily owed their lives to him.

Ewen Montagu returned to law and became a famous judge nicknamed “the Turbulent Judge” for his rude behavior in court, though he proved both fair and occasionally lenient. He died in 1985, believing he had taken the secret of the body’s identity to his grave.

In 1996, amateur historian Roger Morgan discovered Glyndwr Michael’s name in a newly declassified file that a censor failed to redact. The grave was taken over by the Commonwealth War Graves Commission in 1977 and was maintained by the German consulate in Huelva. In 1997, the British government added an inscription to Major Martin’s tombstone officially identifying him as Glyndwr Michael.

Following the first publication of Operation Mincemeat, new details emerged, refining the narrative. Evidence now suggests the team shored up vulnerabilities by retroactively amending the Black Lion Hotel register to include “J. C. Martin.” While the out-of-sequence entry was an obvious alteration, British control over German espionage in Britain mitigated the risk of exposure. Similarly, a bank manager’s letter addressed to the wrong club—initially seen as an error—actually added authenticity through handwritten forwarding notes and corroborating postmarks.

The persona of “Major Martin” was furthered by an expired headquarters pass and a replacement ID card, suggesting a disorganized character. The name Martin was specifically chosen because it began with “M,” placing it outside the A-L coverage of the Navy List available to the Germans at the time. Meanwhile, the real William Martin was in Rhode Island training aircrews.

The deception involved high-level international maneuvers. Historian Denis Smyth confirmed that General Franco personally authorized the transfer of Martin’s documents to Germany. Spanish officers briefed German intelligence before Kurt von Rohrscheidt and Kühlenthal delivered summaries and photographs to Berlin, where Alexis von Roenne endorsed the intelligence.

The operation also intersected with colorful and dark intelligence figures. Dudley Clarke, a pioneer of deception, was arrested in Madrid in 1943 while dressed in women’s clothing; though he claimed it was a ruse to maintain cover, Kim Philby reported the incident to the Soviets. Furthermore, authorized MI6 history revealed a darker 1941 operation where Alan Hillgarth and Leonard Hamilton Stokes abducted official Paul Lewis Claire. Claire was accidentally killed during the struggle, and Ian Fleming helped draft a cover story claiming he had drowned.

The physical details of the ruse were equally meticulous. Martin’s clothing was traced to the widow of H. A. L. Fisher via John Masterman, with all laundry marks removed to prevent tracing. To reinforce the Mediterranean distraction, the SOE launched Operation Animals in Greece. Sabotage efforts, such as the destruction of the Asopos viaduct, successfully convinced the German high command that a Greek invasion was imminent.

Finally, a letter from Cholmondeley’s wartime girlfriend provides a personal coda. Her description of his romantic, modest character—including his reluctance to settle down—echoed the fictional romance created between “Bill” and “Pam” to humanize the man who never was.
