Years ago a special panel of Bundesmarine officers headed by Flotillenadmiral Otto Kretschmer evaluated all data from German sources and data from declassified Royal Navy.
The consensus was good odds that U-47 sank herself with a circular running torpedo. According to logbooks, position reports and individual memories of veterans who participated in that convoy action, U-47 was on the opposite side of the battlefield from HMS Wolverine, making it impossible for HMS Wolverine to have sunk U-47.
This panel concluded that U-47 was sunk by a circular run of her own torpedo and not by HMS Wolverine doing at this time? Prien sank dozens of Allied ships and was great for the Allies that he was killed early in the war.
German uboats touched american soil three times during world war two
In reality, the leader of the group, George Dasch, turned all of them into the FBI. laimed all the credit but only when Dasch called the FBI did they have any idea German saboteurs were in the country.
In spite of many tall tales, German U-boats only touched American soil three times and they didn’t stay very long. Approaching an enemy coast to land agents was extremely dangerous since the boat had to go into shallow water and close an enemy coast with no intelligence.
Since the only real protection a U-Boat had was going deep underwater, being in shallow water made this impossible. Officers and crewmen intensely disliked missions such as this because it put them in such danger.
Over the years, dozens of people have told me how they had heard about German U-Boat coming ashore in the US to shop, go to the movies, have a beer, you name it. Absolutely none of these stories are true. A work colleague many years ago told me UBoat men used to come ashore for an evening of dinner, drinks, and dancing in Palm Beach. His grandfather met many of them. This is impossible but stories like this abound.
I have asked the two top U-Boat historians in the world Jak P Mallman-Showell and Dr. Timothy Mulligan if any of these stories are true and they both said, “no.” And gave me permission to quote them.
NEW YORK TIMES 10 December 1945
Aircraft and many other key armaments, relied on aluminum. As rugged as they seem, you could punch a sharpened pencil through the side of a B-17. Aluminum production in the US skyrocketed during the war. Because it is difficult to make and requires huge amounts of electricity, there are many points in the production cycle which a saboteur could disrupt.

U-Boat Bases and Bunkers: Saint Nazaire: The U-Boat Bunker suffered thirty major raids through the war with three being extremely heavy. The 28 February 1943 raid consisted of 430 bombers, the 22 March 1943 raid consisted of 350 bombers, and the 28 March raid consisted of 320 bombers. The town was almost completely destroyed in these raids while the bunker saw minimal damage.
“The construction work started in February 1941. The bunker, built on the western side of the basin at Saint-Nazaire, was 295m wide, 130m long and 18m high and contained 14 U-boat pens.
After only 4 months the first pens were ready and so Vizeadmiral Dönitz opened on the 30th June 1941 the bunker. U-203 under Kptlt. Rolf Mützelburg was the first boat to use one section of the newly completed shelter.
Later a sluice bunker was also built, which the U-boats used to reach the sea.”
