The South-East Asian Theatre of World War II was the name given to the campaigns of the Pacific War in Burma (now Myanmar), Ceylon, India, Thailand, Indochina, Malaya and Singapore. Conflict in the theatre began when the Empire of Japan invaded Thailand and Malaya from bases located in Indochina on December 8, 1941. The main landing at Singora (now Songkhla) on the east side of the Isthmus of Kra preceded the bombing of Pearl Harbor by several hours. Action in the theatre officially ended on September 9, 1945.
