Refers to the intelligence section of the French armed forces, the “2nd Office” or G2 for Americans. It was present in the different echelons of all the General Staffs operating in the French Navy, Air Force, and Ground Forces. The French 2ème Bureau was re-established in Indochina in October 1945 with the arrival of French re-occupying forces to the south and was extended northwards following the Chinese withdrawal in 1946. Organizationally and theoretically, the 2ème Bureau covered all of Indochina down to the sectorial level and sometimes even lower. However, in reality, there were vast zones of Vietnam, especially in northern and in central Vietnam, that escaped close scrutiny by this military intelligence service. According to a ranking member of the Deuxième Bureau during the Indochina War, Marcel Boussarie, the main objective of this intelligence service was “to make the enemy seen”. Each bureau consisted of a “section étrangère” and a “section Indochine”, with the latter by far the most important and largest in staff. The Indochina section gathered intelligence mainly on political, military, and economic developments in the enemy zone as well as the enemy’s depots, routes, and lines of communications. A third section was added during the war, mainly in the south, the Psychological Warfare Unit. The main territorial Deuxième Bureau offices usually numbered 15 officers and relied on a much larger number of mainly Vietnamese interpreters. But as Boussarie conceded, compared to the equivalent British and American intelligence services in Asia at the time, the French Deuxième Bureau in Indochina was by far the smallest.
