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.
