World War II is filled with heartbreaking stories of bravery, loss, and survival. But some stories, especially those involving soldiers, are so strange they sound almost made up. From bizarre battlefield mishaps to soldiers who refused to stop fighting, these strange facts about soldiers show a very different side of the war.
A Japanese Soldier Kept Fighting for 29 Years After the War Ended

Hiroo Onoda kept fighting on Lubang Island in the Philippines until March 1974, nearly 29 years after Japan surrendered in 1945. He wasn’t just hiding. He believed his orders still stood.
The National Archives states that Onoda had been told not to surrender, and he only gave up after his former commanding officer came to Lubang and officially relieved him of duty. That’s the strange part: the war was over for the world, but not for him.
A 12-Year-Old Boy Earned Combat Honors in the U.S. Navy

Calvin Graham was only 12 when he lied about his age and joined the U.S. Navy in 1942. The Smithsonian reported that he served aboard the USS South Dakota, fought in the Pacific, and was wounded during the Naval Battle of Guadalcanal.
He later received the Bronze Star and Purple Heart, which is hard to process when you remember he should have been in seventh grade. The strange twist came after the Navy learned his real age. Instead of a simple trip home, Graham was punished, lost his medals for a time, and spent years trying to restore his record.
Some American Airmen Literally Died from Farting

Military Newbie claims that some airmen died or were badly harmed because intestinal gas expanded during high-altitude missions.
According to the U.S. Marine Corps mountain medicine handout, altitude can rapidly expand intestinal gas, causing abdominal discomfort and forced gas passage, though it says the condition is not tied to serious consequences.
At around 20,000 feet during bombing runs, that still sounds awful. It’s strange, awkward, and not something you’d want mid-mission.
Hitler’s Nephew Served in the U.S. Navy

William Patrick Hitler, Adolf Hitler’s nephew, ended up serving in the U.S. Navy during World War II. FactRetriever states that he had moved to the United States and later fought against the country ruled by his own uncle.
Before he went to war, he had reportedly written “Why I Hate My Uncle,” which sounds like the title of a family feud no collector of odd history would ever pass up. The timing makes it even stranger. In 1944, while Nazi Germany was still fighting, a man with the last name Hitler wore an American uniform and served against Hitler.
A German Submarine Was Sunk by Its Own Toilet

U-1206 went down in April 1945 because of a toilet problem. Uboat.net states that the German submarine had a newer high-pressure toilet system, and Wired reported that a wrong valve move let seawater flood into the boat. That water reached the batteries, chlorine gas formed, and the sub had to surface near Scotland.
At that point, British forces attacked, and the crew abandoned and scuttled the vessel. Four men died. As a tech guy, I can respect advanced hardware, but this is the nightmare version of adding one feature too many.
Allied Troops Invaded an Island, and Found No One There

On August 15, 1943, U.S. and Canadian troops landed on Kiska Island in Alaska, expecting Japanese defenders. The National Park Service states that the Japanese had slipped away under fog weeks earlier, leaving the island empty.
Information from the National Defense University shows the invasion force had grown to more than 34,000 troops, but the combined force eventually realized it had taken an uninhabited island.
However, men died from friendly fire, mines, traps, and accidents. That’s what makes it so strange. No enemy soldiers were there, yet the operation still ended up deadly.
