The day after the landing at Amagansett, he called Burger, the most guarded and disciplined member of the team, into the upper - story hotel room the two men shared . He walked over to the window and opened it wide . "You and I are going to have a talk," Dasch said, "And if we disagree, only one of us will walk out that door--the other will fly out this window ." He then revealed the truth to Burger: he had no intention of going through with the mission . He hated the Nazis and wanted Burger on his side when he turned the entire plot over to the FBI . Burger smiled . Having spent seventeen months in a Nazi concentration camp, his own feelings for the party were less than warm . He too had been planning to betray the mission . They agreed to defect to the United States immediately . </P> <P> Shaken but not discouraged, Dasch ordered Burger to stay put and keep an eye on the other men . On 15 June, Dasch phoned the New York office of the FBI from a pay - telephone on Manhattan's Upper West Side explaining who he was and asked to convey the information to FBI Director J. Edgar Hoover . When the FBI agent was trying to figure out if he was talking to a crackpot, Dasch hung up . Four days later, he took a train to Washington, D.C. and checked in at the Mayflower Hotel . Dasch then walked into the FBI's headquarters carrying a briefcase, asking to speak with Director Hoover . Dasch bounced from office to office until finally Assistant Director D.M. Ladd, the agent in charge of the manhunt, agreed to humor him with five minutes of his time . Dasch angrily repeated his story after he was dismissed as a crackpot by numerous agents . He finally convinced the FBI by dumping his mission's entire budget of $84,000 on the desk of Assistant Director D.M. Ladd . At this point, he was taken seriously and interrogated for hours . Besides Burger, none of the other German agents knew they were betrayed . Over the next two weeks, Burger and the other six were arrested . FBI Chief J. Edgar Hoover made no mention that Dasch had turned himself in, and claimed credit for the FBI for cracking the spy ring . </P> <Ul> <Li> <P> George John Dasch </P> </Li> <Li> <P> Ernst Peter Burger </P> </Li> <Li> <P> Herbert Haupt </P> </Li> <Li> <P> Heinrich Heinck </P> </Li> <Li> <P> Eddie Kerling </P> </Li> <Li> <P> Herman Otto Neubauer </P> </Li> <Li> <P> Richard Quirin </P> </Li> <Li> <P> Werner Thiel </P> </Li> </Ul>
