In April 1945 the last two Dutch Jedburgh teams became operational. One team code named "Gambling", was a combined Jedburgh/Special Air Service (SAS) group that was dropped into the centre of the Netherlands to assist the Allied advance. The last team was parachuted into the Northern Netherlands as part of SAS operation "Amherst". Despite the fact that operating clandestinely in the flat and densely populated Netherlands was very difficult for the Jedburghs, the teams were quite successful. Jedburgh teams, or parties organised on a similar basis, also operated under the command of Lord Mountbatten in the South East Asia Command (SEAC) areas in 1945, including Japanese-occupied French Indo-China, where sixty French Jedburghs joined the newly created Corps Léger d'Intervention (C.L.I.) fighting the Japanese occupation. In Burma, Jedburgh teams were used in operations "Billet" and "Character". "Billet" was a plan to raise resistance to the Japanese among the majority Burman population, primarily through the largely communist Anti-Fascist Organisation (AFO). "Character" was a scheme to raise the minority Karen people in the Karen Hills between the Sittang and Salween Rivers. The first Jeds to go on Character operations were flown into Burma in February 1945 with Lieutenant Colonel Peacock's Special Groups. Many of the surviving American "Jeds" later held various positions of great responsibility in the US Army or the CIA. Examples include William Colby, who became director of the CIA, Lucien Conein, who was a key CIA officer in Vietnam, General John Singlaub and Colonel Aaron Bank (first commander of United States Army Special Forces). Among French Jedburghs were Paul Aussaresses, later founder of the SDECE's 11e RPC, and war criminal in French Algeria; Jean Sassi, another who later served in the 11e RPC, who pioneered conventional guerrilla commandos GCMA with Roger Trinquier during the First Indochina War; Guy Le Borgne, commander of the 8e Choc Parachute Battalion in Indochina, the 3rd Marine Infantry Parachute Regiment in Algeria and 11th Parachute Division. In "You're Stepping On My Cloak and Dagger", a memoir of his offbeat adventures as an agent in the O.S.S., Roger Wolcott Hall describes his work with the Jedburghs. Hall's first assignment with the O.S.S. was as a Special Operations instructor, at the Congressional Country Club in Maryland which had been converted into a training center.
