Duquesne was quite a guy. The stories of his escaping prisons, sinking British ships and running a German spy ring in New York are no exaggeration and have been well documented by reputable sources, including the New York Police Department and the FBI :


... e-spy-ring.

His claim that he ordered the sinking of Kitchner's ship torpedoed by a U-Boot seems far fetched, but the story is written in Duquesne's own hand and was published in Clement Wood's biography: The Man Who Killed Kitchener. Other biographers have serious questions about the authenticity of the Kitchner story, and some have also questioned the authenticity of several of Duqesne's war medals. Better documented is Duquesne's failed attempt to kill Kitchner in Cape Town during the Boer War, and his earlier orders to kill the Chief of Scouts, Frederick Russell Burnham.

Second World War - Duquesne Spy Ring

On 28 June 1941, following a two-year investigation, the FBI arrested Duquesne along with two associates on charges of relaying secret information on Allied weaponry and shipping movements to Germany. Agents successfully filmed members of Duquesne's ring as they provided information to William G. Sebold, a confidential FBI informant and double agent.[13] They were found guilty in what was the largest espionage ring conviction in the history of the United States. On 2 January 1942, the 33 members of the Duquesne Spy Ring were sentenced to serve a total of more than 300 years in prison. One German spymaster later commented that the ring’s roundup delivered ‘the death blow’ to their espionage efforts in the United States. J. Edgar Hoover called his FBI swoop on Duquesne's ring the greatest spy roundup in U.S. history.[14] During the trial, Duquesne claimed that his actions were aimed at the UK as revenge for the crimes done to his people and his country during the Second Anglo-Boer War.

The 64-year-old Fritz Joubert Duquesne did not escape; he was sentenced to 18 years in prison. He also received a 2-year concurrent sentence and the imposition of a $2,000 fine for violation of the Foreign Agents Registration Act. He served his sentence in Leavenworth Federal Penitentiary in Kansas, where he was mistreated and beaten by inmates. In 1954, he was released owing to ill health, having served 13 years. He died indigent at City Hospital on Welfare Island (now Roosevelt Island) on 24 May 1956 at the age of 78 years.
