The Special Intelligence Service was a covertcounterintelligence branch of the United States Federal Bureau of Investigation located in South America during World War II. It was established during the term of U.S. President Franklin D. Roosevelt to monitor Axis activities in Central and South America. In 1934, President Roosevelt began to grow concerned about activities of Nazi groups within the United States. The FBI was ordered to begin investigating these groups operating within the country. The goal of this work was to determine if foreign agents were working within these American Nazi groups. In 1940, the government decided to expand the scope of this mission. There were more than 1.5 million expatriate Germans living in South America, including Argentina and Brazil. As a result, this area had become an active area of Axis espionage, propaganda and sabotage. In June 1940, President Roosevelt ordered the formation of the Special Intelligence Service to monitor these activities. The SIS allied with the BIS in Latin America. It is presumptive that Assistant Director Percy E. "Sam" Foxworth was the first chief of the SIS. He died in a plane crash on 15 January 1943 with agent Harold Dennis Haberfeld. The second chief appears to have been Jerome Doyle. The front for the organization was actually an operating law firm, called the "Importers and Exporters Service Company." It operated out of room 4332 of the International Building at 30 Rockefeller Center—the RCA Building—beginning in August 1940. The organization took some time to become fully operational, due to language and cultural differences, but within a year the SIS had a number of agents in place under various covers. This organization placed more than 340 undercover agents in regions of Latin America. They operated for seven years, and by 1946 a total of 887 Axis spies had been discovered. Also found were 281 agents of Axis propaganda, 222 smugglers shipping important war materials, and more than 100 saboteurs and other operatives. It located 24 secret Axis radio stations and confiscated 40 radio transmitters and 18 receiving sets. Following the war the SIS was disbanded, having been in operation in 1940–1946. After it was disbanded, its region of operation was incorporated into the responsibilities of the newly formed Central Intelligence Agency. Concurrently, the FBI would expand its own primarily domestic counterintelligence role to hunt spies and combat espionage.
Argentina
The SIS oversaw the destruction of the Abwehr radio HDZ, which transmitted messages to Nazi receiving stations in Europe. It was instrumental in breaking the code of the German Enigma machine.
Bolivia
An investigation labeled the "Jar case" remains classified.
Chile
German radio transmitter PQZ was silenced. Guiflermo Hellemann, one of the leader of the spy and sabotage ring was deported to the United States and interrogated.
Colombia
The apprehension of a German agent in Colombia led to the identification of German agents in the United States.

The SIS report:
Paraguay
On 31 March 1945, Special Agent Jeremiah Cordes Delworth was "presently serving" as the FBI Legal Attache in Asuncion, Paraguay. He died in a plane crash on 3 December 1945 near Laguna Ibera, Santo Tome, Corrientes Provence, Argentina. The Argentine Death Certificate gives the names of Gordon Brittain Whelplay and Richard William Scheitzer as witnesses. The aircraft of the crash was a U.S. Army C-47, No. 8602. According to Argentine reports, bad weather was the cause. Fourteen were killed in the crash. The flight was from Asuncion to Montevideo, Uruguay. The pilot was Lt. Orville Mitchelsen of California and 3 crew members. The other military victims were Lt. Zane Glicher of Massilon, Ohio; Lt. Chester Lowe of Washington, D. C.; Lt. William Nunnemaker of Kansas; Lt. Ruben Klein of New York; Sgt. James Roberson of St. Louis, Mo.; Sgt. Clarence Setko of Superior, Wis.; Sgt. Richard Schweitzer of Gloversvflle, N. Y.; Cpl. Frank Dubinskas of MeKees Rocks, Pa.; Cpl. David Kellogg of Newtonville, Mass.; Charles Brown and E. S. King, crew members, and Leopold. The burned aircraft was found in rough country twenty-three miles south of the hamlet of Pellegrini. The purpose of the military passengers was a U.S. Army "geodetic mission". A geodetic mission collects Geodetic datum. It was deemed too difficult to recover the bodies and a gasoline can was parachuted to the search party that located the wrecked plane for the purpose of cremation.
Venezuela
Ten sabotage agents were interned in the town of Rubino by the Venezuelan government. Special Agent Robert Howard Calhoun arrived in Venezuela on his first SIS assignment on February 18, 1943. He was assigned as Vice Consul in Ciudad Bolivar, Venezuela, as a cover story. While in Ciudad Bolivar, Agent Calhoun handled investigations involving espionage, sabotage, subversive activity and diamond smuggling. After ten months, he was transferred to Caracas as Assistant Legal Attache. In January, 1944, all cases relating to political and Communist activity were assigned to him. Thomas J. Maleady, Second Secretary of the United States Embassy, was dependent upon Calhoun's reports for his information. Calhoun developed contacts and confidential informants. Many contacts and confidential informants developed by him in Ciudad Bolivar continued to furnish him with information, although he was not able to contact then personally while in Caracas. Calhoun led and directed raids against fascists and participated in dangerous assignments. He later transferred to the New York City FBI division, probably around October 1944.
