- A Nazi submarine intended to wreak havoc on the United States failed its mission after a series of missteps, according to newly released files.
- The ship ran aground in New York and four German agents sneaked into the United States.
- A U.S. coastguard discovered the Germans as they buried their supplies on the beach, but he was persuaded to keep quiet.
A Nazi submarine mission to the United States during World War II that aimed to unleash a wave of terror ended in farce after being hit by a series of disasters, newly released files showed on Monday.
The Germans planned to bomb roads, railways and factories on "Operation Pastorius" in June 1942, according to the files from Britain's MI5 domestic intelligence agency.
But even before it got under way the plot descended into a farce worthy of a comedy film.
One of the saboteurs, Herbert Haupt, got drunk in a Paris bar after a farewell dinner and declared to his drinking companions that he was a spy.
When the submarine arrived in the United States, it ran aground on a sandbar as it dropped off the four agents on the coast of Long Island, New York.
A U.S. coastguard discovered the Germans as they buried their supplies on the beach -- but he was given $300 and persuaded to leave the men alone.
In a report on the mission, Victor Rothschild, head of MI5's counter-espionage division, wrote: "It was only owing to the laziness or stupidity of the American coastguards that this submarine was not attacked by USA forces."
The plot was only foiled when the leader of the spies, George Dasch, rang up the FBI, announced he was a saboteur and demanded to speak to the bureau's then director, J. Edgar Hoover.
His confession was initially dismissed but after a lengthy interview he was arrested and his fellow agents were rounded up, the files showed.
Despite the clumsiness of the mission, MI5 still regarded it as a serious threat.
"This sabotage expedition was better equipped with sabotage apparatus and better trained than any other expeditions of which the security service has heard," Rothschild wrote.
