Although he had never before served in the Far East, as CEFEO commander, Leclerc was charged with recovering French Indochina. This territory, comprising the present day states of Vietnam, Cambodia and Laos, had been conquered by the French during the late 19th and early 20th centuries. The Vichy regime had allowed the Japanese to use Indochina as a base from which to attack the Allies in Malaya, Burma and China. On 9 March 1945, the Japanese had deposed the French colonial government, taken direct control of Indochina, defeated the French army in several engagements, and imprisoned surviving French soldiers.
