ISBN: 9780806544137
How much do you know of the FBI's role in hunting down spies during World War II? Did you know of the FBI's activities in South America and the Caribbean islands early in the war? Did you know that Director Hoover had an obsessive belief that the FBI was the best tool to root out American traitors in Europe instead of the Oh-So-Social (OSS) that President Roosevelt favored? In G.I. G-Men, Stephen Harding lays out the story of what Director Hoover managed to extract from the President and what they accomplished.
After the United States joined the fighting in World War II, the FBI sent some agents over to England to liaison with the British on domestic and foreign security practices. It was brought to the FBI's attention that there were certain American individuals such as Ezra Pound who were aiding and abetting the Axis powers against the United States. Since the FBI was the domestic lead for counter-intelligence within the USA, and had been authorized by the President to work covertly in Central and South America in 1940, why not allow a small group of FBI special agents to be embedded with the US military to assist with the apprehension and processing of any Americans found aiding the Axis powers who had been indicted by the Department of Justice while also investigating those other Americans who had stayed in occupied Europe to see if they merited an indictment. So the Army Liaison Unit (ALU) was formed and operated in France, Italy, Austria, Hungry, and Germany from 1943 until 1945. They helped capture Ezra Pound in Italy, investigated W. Dawson who had ties to both Teddy Roosevelt and FDR, hunted for dirt on Florence Gould, the wife of one of the richest Americans, and a host of others. Some were indicted, others were not ultimately charged due to lack of evidence. The ALU worked diligently until the OSS and the US Military Forces in European Theater intelligence chief managed to get their authorization revoked at the end of 1945. Harding ends the book with a discussion of what the ALU accomplished and what the agents did after the war.
