Japanese Surrendered Personnel operated in the War in Vietnam of 1945–1946. They played a key role in supporting British, British Indian and French Imperial forces in what was the time French Indochina. The operation – Operation Masterdom as it was commonly known – was overwhelmingly successful and led to the restoration of French rule in Indochina. Casualties were estimated at at least 2,700 personnel dead for the Viet Minh and less than 100 total for the allied forces.
