Thailand's WWII Role and the Bridge Over the River Kwai

Thailand, under Field Marshal Plaek Phibunsongkhram, allied with Japan during World War II, allowing Japanese forces to use its territory for attacks on Malaya, Burma, and Singapore. The most infamous contribution was the construction of the Thailand-Burma railway, known as the Burma Death Railway, which included the Bridge over the River Kwai. Built from 1942 to 1943 by 60,000 Allied POWs and 200,000 civilian laborers (Rōmusha), the railway stretched over 420 miles from Ban Pong to Thanbyuzayat. Approximately 16,000 POWs and 90,000 laborers died due to brutal conditions. The bridge was destroyed by an Allied air raid in 1944. Phibun's regime provided funds and approval for the railway, implicating Thailand in war crimes. The Free Thai Movement, led by Pridi Banomyong, opposed Phibun and aided the Allies. Allied air raids targeted Bangkok from early 1942, causing thousands of civilian casualties. Phibun resigned in 1944, replaced by Khuang Aphaiwong. After the war, Phibun was tried under the War Criminals Act of 1945 but returned to power in 1948.
