During the Second World War did the Japanese Imperial Army Invaded Thailand?

On December 8, 1941, a few hours after the attack on Pearl Harbor, Japan demanded the right to move troops across Thailand to the Malayan frontier. Japan invaded the country and engaged the Thai army for six to eight hours before Phibun ordered an armistice. Shortly thereafter Japan was granted free passage, and on December 21, 1941, Thailand and Japan signed a military alliance with a secret protocol wherein Tokyo agreed to help Thailand get back territories lost to the British and French colonial powers and Thailand undertook to assist Japan in her war against the Allies.





In early January 1941, Thailand invaded French Indochina, beginning the French-Thai War. The Thais, better equipped and outnumbering the French forces, easily took Laos. The French decisively won the naval Battle of Koh Chang.





The Japanese mediated the conflict, and a general armistice was declared on January 28. On May 9 a peace treaty was signed in Tokyo, with the French being coerced by the Japanese into relinquishing its hold on the disputed territories.





After the end of World War II, Prime Minister Pridi Phanomyong agreed to return the captured territories to France, as a condition for admission to the newly created United Nations.





After Japan's defeat in 1945, with the help of a group of Thais known as Seri Thai who were supported by the United States, Thailand was treated as a defeated country by the British and French, although American support mitigated the Allied terms. Thailand was not occupied by the Allies, but it was forced to return the territory it had gained to the British and the French. In the postwar period Thailand enjoyed close relations with the United States, which it saw as a protector from the communist revolutions in neighbouring countries.
