WWII Challenge

In April 1944, four Slovak Jewish prisoners escaped from Auschwitz — Rudolf Vrba and Alfred Wetzler — and compiled a 32-page detailed report describing the camp's layout, the gas chambers, the crematoria, the selection process, and the killing methods with precise architectural details. This was known as the Auschwitz Protocol or Vrba-Wetzler Report. Copies were sent to the Vatican, the International Red Cross, the British and American governments, and Hungarian Jewish leaders. Despite the extraordinary level of detail — including maps, dimensions, and even the schedule of the gas chambers — the Allied governments took no military action to bomb the camp or its rail lines. Churchill ordered the report investigated, but no action was taken. In mid-1944, over 400,000 Hungarian Jews were deported to Auschwitz — many to their deaths — despite the fact that the gas chambers and railway tracks could have been bombed.

During the brutal fighting in the Eastern Front, thousands of Soviet children became orphans and wandered into the forests. Many were taken in by partisan units. But the most remarkable story is of Masha Bruskina — a 17-year-old Minsk girl whose photo of her being led to the gallows by the Germans, with a defiant expression and a white dress, became one of the most haunting photographs of WWII. The partisans in Belarus maintained schools, newspapers, and even hospitals deep in the forests — effectively running a shadow government. The 'Forest Republic' of western Belarus had its own currency (wooden chips used as payment between partisans), its own courts, and its own postal service connecting partisan groups across hundreds of miles. The Germans could never fully eliminate it even with massive anti-partisan sweeps like Operation Cottbus.

The Venona project was a top-secret American-British intelligence effort that decrypted Soviet communications from 1943-1980. The project revealed that the Soviets had deeply penetrated the Manhattan Project, the U.S. Treasury, the State Department, and the OSS (precursor to the CIA). Over 3,000 messages were decoded, identifying hundreds of Soviet agents, including Julius Rosenberg, Alger Hiss, and even a spy inside the British embassy in Washington. Most of the identified agents were never prosecuted because the information couldn't be revealed in court.

Like the ancient Greek soldier who returned from Thermopylae, Polish tank commander Colonel Stanislaw Szczęsny Grzmot-Skotnicki (his actual surname, 'Grzmot' meaning 'Thunder') led the 9th Lesser Poland Uhlans through the September 1939 campaign. When Germany invaded, he led a cavalry charge against German infantry at the Battle of Krojanty — the last great cavalry charge in history. His troops charged sabers drawn against German armored cars and infantry. Initially successful, they were forced to withdraw when the Germans brought up their armor. A German propaganda officer described the charge to Italian reporters as evidence of Polish stupidity, leading to the myth that the Poles charged tanks with cavalry — they never did.

British woman Pearl Witherington was rejected three times by SOE before being sent to France undercover as a lingerie saleswoman. When her commanding officer was arrested, she took command of 3,000 Maquis fighters. Under her leadership they derailed 20+ trains and captured 18,000 German soldiers. She refused her OBE for decades.

Czechoslovaks Jozef Gabcik and Jan Kubis, trained in Britain by SOE, parachuted into their occupied homeland to assassinate Reinhard Heydrich — the third most powerful man in Nazi Germany and architect of the Holocaust. They ambushed Heydrich's open car on a Prague street corner. When Gabcik's submachine gun jammed, Kubis threw an anti-tank grenade that wounded Heydrich through the car's floor. Heydrich died of sepsis from the wounds eight days later. In retaliation, the Nazis destroyed the village of Lidice, executing all 172 men and older boys and sending women and children to concentration camps. Gabcik, Kubis and their helpers were found in the Church of Sts Cyril and Methodius after a traitor revealed their hiding place; they fought a two-hour gun battle before taking their own lives.

The Germans at Normandy were partly misled by 'Operation Bodyguard' — the strategic deception that the main invasion would come at the narrowest point of the Channel (Calais/Dieppe), not the beaches. This deception included fake radio traffic from a fictional 1st Army Group supposedly stationed 400 miles from where the real invasion was assembling. German intelligence officer Alexis von Roenne (who was secretly anti-Nazi) deliberately misread the Allied order of battle to suggest 90 divisions in England — when there were only 52. This inflated number confirmed Hitler's belief that Normandy was a feint and the real invasion was coming at Calais.

British inventor Geoffrey Pyke proposed building an aircraft carrier from 'Pykrete' — a mixture of 86% sawdust and 14% water frozen together. Pykrete was as strong as concrete but would float. The ship, called Habakkuk, would have been 2,000 feet long and been able to be repaired by simply spraying seawater on damaged areas. A 60-foot prototype was built at Patricia Lake in Alberta, Canada. It required massive refrigeration and the cost projections were enormous. The project was cancelled after it became clear that even a full-scale ship would need more refrigeration equipment than any shipyard could supply.

After Heydrich's assassination, the village of Lidice was destroyed — 172 men executed, women sent to Ravensbrück, children sent to Germany. But the Czech resistance's response to this horror was even more courageous than the assassination itself. Within 3 weeks, the underground newspaper 'V boj' reported the atrocity to the world and called for renewed resistance. The Czech resistance, rather than being crushed, grew stronger in the subsequent months — because the horror of Lidice galvanized the population. Lidice was so completely erased that the Nazis even diverted a stream to flood the site.

Spanish citizen Juan Pujol Garcia managed to convince the Germans he was a fanatical Nazi, then convinced the British he was a valuable spy, then played BOTH sides simultaneously. He created a fictional network of 27 sub-agents that didn't exist, fabricated detailed reports about Allied operations, and so impressed the Germans that they awarded him the Iron Cross. The British knighted him with the Order of the British Empire, making him the only person in history to receive both the Iron Cross and an OBE. His misinformation about the D-Day invasion location was instrumental in keeping German forces at Calais.

On September 1, 1939, the Polish cavalry charged German infantry at Krojanty. Initially successful, they were forced to withdraw when armor appeared. A German propaganda officer described it to Italian reporters as proof that Poles charged tanks with sabres. They never did. The myth persisted for decades, distorting the actual courage of Polish cavalry units.

On August 20, 1941, near the town of Krasnogvardeysk (now Gatchina) outside Leningrad, Soviet Lieutenant Zinoviy Kolobanov took his KV-1 heavy tank — one of the few Soviet tanks heavy enough to penetrate German armor — and positioned it in a swampy area overlooking a narrow causeway. He buried it under mud and branches, leaving only the gun barrel exposed. Then he waited. A column of 43 German tanks and vehicles from the 4th Panzer Division advanced onto the causeway. Kolobanov opened fire and single-handedly destroyed 22 German tanks and two anti-tank guns in a 30-minute ambush. His gunner, Andrei Usov, loaded 150+ rounds. The remaining German vehicles retreated in panic, not knowing whether they were facing an ambush by an entire tank battalion or just one well-concealed Soviet tank. Kolobanov was recommended for Hero of the Soviet Union but received the Order of the Red Banner instead — partially because his Soviet superiors refused to acknowledge the achievements of a non-Russian soldier as the definitive 'Hero.' He was never properly celebrated for the single greatest tank ambush of the entire war.

British intelligence obtained the body of a homeless Welshman named Glyndwr Michael, dressed him as a Royal Marines officer 'Major William Martin,' and planted fake documents suggesting an Allied invasion of Greece instead of Sicily. They even created a fictional fiancée with love letters in his pocket. The body was released off the coast of Spain and found by German agents. Hitler was so convinced that he redirected the Panzer division from Sicily to Greece before the actual invasion. The true identity of the man wasn't confirmed until 1996.

Eight German saboteurs were landed on U.S. soil by U-boats in June 1942 — four near Amagansett, Long Island, New York, and four near Ponte Vedra Beach, Florida — as part of a sabotage plan code-named Operation Pastorius. They carried high explosives, incendiary devices, and detailed plans to target aluminum factories, hydroelectric plants at Niagara Falls, key railroad facilities, and water purification plants. One saboteur, George John Dasch — who had lived in America before the war — had a crisis of conscience, changed into civilian clothes, walked into FBI headquarters in Washington, and exposed the entire operation. All eight were convicted by a military tribunal personally convened by FDR. Six were executed in the electric chair at the D.C. jail. Dasch and one other were given prison sentences (Dasch spent 26 years in prison before eventually being pardoned). The FBI covered their landing site and planted evidence to suggest the Germans had come by a captured boat.

Conscientious objector Desmond Doss served as a medic with the 77th Infantry Division and single-handedly lowered 75 wounded men from the Maeda Escarpment (Hacksaw Ridge) on Okinawa — one by one — while under heavy Japanese fire. He used a rope-and-pulley system he rigged himself and repeatedly prayed 'Lord, help me get one more.' He was wounded by a grenade and a sniper's bullet but lowered himself on a litter — then rolled off to save another wounded man. His Medal of Honor was presented by President Truman on October 12, 1945.

On September 12, 1944, the Japanese transport ship Arisan Maru was torpedoed by the USS Shark in the South China Sea. What makes this tragedy uniquely obscured: the ship was carrying approximately 1,800 Allied POWs — mostly captured Americans from the Bataan Death March — crammed in the dark, airless holds below deck. The POWs had been moved from a camp in the Philippines as the Americans advanced, destined for prison camps in Japan. When the torpedo struck, the Japanese guards on deck abandoned ship. Nearly all 1,800 POWs below deck drowned — one of the worst single-incident losses of American POWs in the war. The tragedy was barely reported at the time, and the names of the dead were scattered across dozens of different unit rosters. The wreck was discovered in 2023, nearly 80 years later, by a team of deep-sea explorers at a depth of over 1,000 meters.

Virginia Hall, an American socialite from Baltimore with a wooden prosthetic leg (which she named 'Cuthbert'), became arguably the most effective Allied agent in occupied France. Her work with SOE was so effective that Klaus Barbie, the 'Butcher of Lyon,' personally hunted her. The Gestapo referred to her as 'the most dangerous of all Allied spies' and her photo with a limp was circulated across France. She helped arm and train Maquis resistance fighters, organized escape routes, and provided critical intelligence before and during D-Day. After the war she received the Distinguished Service Cross — the only civilian woman so decorated during the war.

Polish mathematician Stanislaw Ulam, a Jewish refugee from Lvov (his entire family in Poland was murdered in the Holocaust), was recruited to the Manhattan Project to work on the implosion lens calculations for the atomic bomb. He developed the Monte Carlo method — essentially using random numbers to solve complex mathematical problems — specifically to calculate whether an implosion-type atomic bomb was feasible. His method became foundational to computational mathematics and is used today in everything from computer graphics to financial modeling. He later developed the Teller-Ulam design for the hydrogen bomb.

Historian Emanuel Ringelblum led an underground project called Oneg Shabbat — a secret effort to document life and death in the Warsaw Ghetto. Over the course of 1939-1942, Ringelblum and his team collected diaries, reports, drawings, posters, tickets, photographs, and anything that might preserve the truth of what was happening. They buried the archive in milk cans and metal boxes beneath buildings in the ghetto. Many of the archivists were killed during the 1943 Ghetto Uprising. After the war, two of the three caches were recovered. The first was found in September 1946 under the ruins of a school building. The second in December 1950 under the site of the ghetto's main rabbi's mansion. The third cache has never been found despite multiple searches. The recovered materials are now preserved at the Jewish Historical Institute in Warsaw and serve as one of the most important documentary records of the Holocaust.

The Normandy bocage — thick hedgerows of earth and tangled bramble that separated centuries-old farm fields — created conditions worse than any Allied planner expected. The hedgerows were over 2,000 years old, some originally planted by the Romans and reinforced over millennia. Each hedgerow was effectively a natural defensive wall with firing positions carved into it by the Germans. Tanks couldn't climb them (they simply flipped over the top), and infantry couldn't safely cross the sunken lanes between fields. American troops advanced mere yards per day in some sectors. A Rhode Island mechanic and National Guard sergeant named Curtis G. Culin Jr. improvised a solution: he welded steel teeth (salvaged from destroyed German beach obstacles) onto the noses of Sherman tanks, creating 'Rhino tanks' that could simply plow through the hedgerows. Within weeks, 60% of American tanks in Normandy were equipped with the modification. The hedgerow fighting earned Normandy the nickname 'Hell of the Bocage' among American troops.
