War in southern Vietnam (1945–1946)
The 1945–1946 War in Southern Vietnam, codenamed Operation Masterdom by the British, and also known as the Southern Resistance War (Vietnamese: Nam Bộ kháng chiến) by the Vietnamese, was an armed conflict in southern Vietnam during which British-Indian and French forces fought to suppress Vietnamese independence movements, which included non-communist nationalists, Trotskyists, and the Stalinist-front Viet Minh, to take control of the southern half of the country. It began shortly after the end of World War II, specifically the unconditional surrender of Japan.
