Since Sebold's passport had been stolen shortly after his first visit from Gassner, Sebold went to the American consulate in Cologne, Germany to obtain a new one. While there, Sebold secretly told consulate personnel about his future role as a German agent and expressed his wish to cooperate with the FBI when he got back to America. Sebold reported to Hamburg, Germany, where he was instructed in such areas as preparing coded messages and microphotographs. On completion of training, he was given five microphotographs containing instructions for preparing a code and detailing the type of information he was to transmit to Germany from the United States. Sebold was told to retain two of the microphotographs and to deliver the other three to German operatives in the United States: Fritz Joubert Duquesne, Hermann Lang, and one other. After receiving final instructions, including using the assumed name Harry Sawyer, he sailed from Genoa, Italy, and arrived in New York City

The FBI previously had been advised of Sebold's expected arrival, his mission, and his intent to assist in identifying German agents in the United States. Under the guidance of special agents, Sebold established residence in New York City as Harry Sawyer. Also, an office was set up for him as a consulting diesel engineer, to be used as a cover in establishing contact with members of the spy ring. In selecting the office for Sebold, FBI agents ensured that they could observe any meetings taking place there.

Duquesne provided Sebold with information for transmittal to Germany during subsequent meetings, and the meetings which occurred in Sebold's office were filmed by FBI Agents. Duquesne, who was vehemently anti-British, submitted information dealing with national defense in America, the sailing of ships to British ports, and technology. He also regularly received money from Germany in payment for his services.

On one occasion, Duquesne provided Sebold with photographs and specifications of a new type of bomb being produced in the United States. He claimed that he secured that material by secretly entering the DuPont

Before fleeing to Germany to escape prosecution, Dr. Griebl had been implicated in a Nazi spy ring with Guenther Gustave Rumrich, who was tried on espionage charges in 1938.

Bante assisted Paul Fehse in obtaining information about ships bound for Britain with war materials and supplies. Bante claimed that as a member of the Gestapo his function was to create discontent among union workers, stating that every strike would assist Germany.

Sebold met Bante at the Little Casino Restaurant, which was frequented by several members of this spy ring. During one such meeting, Bante advised that he was preparing a bomb fuse, and he subsequently delivered dynamite and detonation caps to Sebold.

Paul Fehse, a major figure in this case, informed Germany that Blank, who was acquainted with several members of the spy ring, could secure some valuable information but lacked the funds to do so. Later Fehse and Blank met with Sebold in his office. They told Sebold that Blank could obtain details about rubberized self-sealing airplane gasoline tanks, as well as a new braking device for airplanes, from a friend who worked in a shipyard. However, he needed money to get the information.

Blank pleaded guilty to violation of the Foreign Agents Registration Act. He received a sentence of 18 months' imprisonment and a $1,000 fine.

A native of Germany, Alfred E. Brokhoff, went to the United States in 1923 and became a naturalized citizen in 1929. He was a mechanic for the United States Lines in New York City for 17 years prior to his arrest. Because of his employment on the docks, he knew almost all of the other agents in this group who were working as seamen on various ships.

Brokhoff helped Fehse secure information about the sailing dates and cargoes of vessels destined for England. He also assisted Fehse in transmitting this information to Germany. Also, another German agent, George V. Leo Waalen, reported that he had received information from Brokhoff for transmittal to Germany.

Upon conviction, Brokhoff was sentenced to serve a five-year prison term for violation of the espionage statutes and to serve a two-year concurrent sentence for violation of the Registration Act.

Closely associated with Franz Stigler, one of the principal contact men for this spy ring, Clausing operated as a courier. He transported microphotographs and other material from the United States to South American ports, from which the information was sent to Germany via Italian airlines. He also established a mail drop in South America for expeditious transmittal of information to Germany by mail.

Clausing was convicted and was sentenced to serve eight years for violation of espionage statutes. He also received a two-year concurrent sentence for violation of the Registration Act.

Dold was sentenced to serve 10 years in prison on espionage charges and received a 2-year concurrent sentence and a fine of $1,000 for violation of the Registration Act.

Rudolf Ebeling

After leaving Germany for the United States in 1925, Rudolf Ebeling was employed as a foreman in the Shipping Department of Harper and Brothers in New York City when he was arrested.

Ebeling obtained information regarding ship sailings and cargoes, which he provided to Paul Fehse for transmittal to Germany. He also furnished such information to Leo Waalen, who delivered the material to Sebold for transmittal.

Upon conviction, Ebeling was sentenced to 5 years in prison on espionage charges. He also received a 2-year concurrent sentence and a $1,000 fine for violating the Registration Act.

A native of Germany, Heinrich Carl Eilers went to the United States in 1923 and became a citizen in 1932. From 1933 until his arrest, he served as a steward on ships sailing from New York City.

Eilers made a trip from New York to Washington, D.C., to obtain information for Germany from the Civil Aeronautics Authority. His mission, however, was unsuccessful.

At the time of his arrest in New York City by Customs authorities in June, 1940, he had in his possession 20 letters addressed to people throughout Europe. He also had books relating to magnesium and aluminum alloys which had been sent to him by Edmund Carl Heine, one of the principal espionage agents in this group.

Upon conviction, Eilers received a 5-year prison sentence on espionage charges and a concurrent sentence of 2 years' imprisonment and a $1,000 fine under the Registration Act.

Paul Fehse

In 1934, Paul Fehse left Germany for the United States, where he became a citizen in 1938. Since his arrival in the United States, he had been employed as a cook aboard ships sailing from New York Harbor.

Fehse was one of the directing forces in this espionage group. He arranged meetings, directed members' activities, correlated information that had been developed, and arranged for its transmittal to Germany, chiefly through Sebold. Fehse, who was trained for espionage work in Hamburg, Germany, claimed he headed the Marine Division of the German espionage system in the United States.

Having become quite apprehensive and nervous, Fehse made plans to leave the country. He obtained a position on the SS Siboney, which was scheduled to sail from Hoboken, New Jersey, for Lisbon
