In 1944 another attempt at infiltration was made, codenamed Operation Elster ("Magpie"). Elster involved Erich Gimpel and German-American defector William Colepaugh. Their mission's objective was to gather intelligence on a variety of military subjects and transmit it back to Germany by a radio to be constructed by Gimpel. They sailed from Kiel on and landed at Hancock Point, Maine, on November 29, 1944. Both then made their way to New York, but the operation soon collapsed. Colepaugh lost his nerve and turned himself in to the FBI on December 26, confessing the whole plan and naming Gimpel. Gimpel was then arrested four days later in New York. Both men were sentenced to death, but eventually their sentences were commuted. Gimpel spent 10 years in prison, while Colepaugh was released in 1960 and operated a business in King of Prussia, Pennsylvania, before he retired to Florida.
