Heroic Capture of German U-Boat

[June 7, 2026]  I often write about heroes here on my blog.  And, I will highlight another heroic act today.  The reason I do this is simple; we have a moral obligation to tell stories of heroes.  In an X post by @HiddenHistory, the secret story of the heroic capture of German U-Boat U-505 is revealed.

82 years ago, eight American sailors jumped onto a sinking Nazi submarine in the middle of the Atlantic.

What they pulled out of it changed the war. And the Navy buried the whole story for years.

First, you need to know that U-505 was already cursed. German sailors called her the unluckiest boat in the fleet. In October 1943, during a brutal British depth-charge attack, her own captain shot himself in the head in the control room, in front of his crew. He remains the only submarine commander in history known to have killed himself underwater in combat. His second-in-command calmly took over, rode out the attack, and sailed her home.

Eight months later, her luck ran out completely.

June 4, 1944. Two days before D-Day. Captain Daniel Gallery’s hunter-killer group, built around the escort carrier USS Guadalcanal, had been stalking U-boats off West Africa. Gallery had an idea his superiors considered borderline insane: don’t sink the next one. Capture it. No US Navy crew had boarded and taken an enemy warship on the high seas since 1815.

The destroyer escort USS Chatelain caught U-505 on sonar and fired a salvo of hedgehog bombs. The U-boat broke the surface 700 yards away. Gunfire raked the conning tower, wounding her captain. He gave the order to abandon ship.

The Germans rushed out so fast they botched the scuttling. The sub was flooding, but her engines were still running. She was circling the battle at six knots, empty, sinking, and very possibly rigged with demolition charges.

So Lt. Albert David and eight men from USS Pillsbury chased her down in a whaleboat, leaped aboard, and climbed down the hatch into a dark, flooding submarine that could explode or go under at any second. They shut the scuttling valves, disarmed the charges, and stopped the flooding.

Down there they found the prize: Enigma cipher machines and roughly 900 pounds of codebooks and charts. Current settings. The keys to the German navy’s secret communications.

But here’s the catch. The treasure was only valuable if Germany never found out. One leak and Berlin changes every code overnight.

So the Navy ran one of the great cover-ups of the war. The sub was towed 1,700 miles to Bermuda and given a fake American name: USS Nemo. Around 3,000 sailors were sworn to total silence. The 58 captured German crewmen vanished into a POW camp in rural Louisiana, hidden even from the Red Cross. Germany declared U-505 lost with all hands and notified the families. The dead men were alive in Louisiana, and their boat was working for the US Navy.

The secret held until the war ended.

Lt. David received the Medal of Honor, the only one awarded in the Atlantic Fleet in all of WWII.

And the submarine? In 1954, Chicagoans raised $250,000 to bring her home. She was towed across Lake Michigan and dragged through the streets of Chicago to the Museum of Science and Industry.

She’s still sitting there right now. You can walk through her.

NOTE: The POW camp was located about an hour’s drive from where I grew up in Northeast Louisiana.  Camp Ruston was one of the largest POW camps in the U.S. at one point in the war.
