TheFree Thai Movement (Thai:เสรีไทย,RTGS: Seri Thai,pronounced[sěː.rīːtʰāj]) was a Thai undergroundresistance movement against theEmpire of Japan during theSecond World War. The Free Thai Movement were an important source ofmilitary intelligence for theAllies in the region.
In the aftermath of theJapanese invasion of Thailand on 7–8 December 1941, the regime ofPlaek Phibunsongkhram (Phibun)declared war on theUnited Kingdom and theUnited States on 25 January 1942.[1]Seni Pramoj, the Thai ambassador in Washington, refused to deliver the declaration to the United States government.[2]
Accordingly, the United States refrained from declaring war on Thailand.[2] Seni, a conservative aristocrat whose anti-Japanese credentials were well established, organized the Free Thai Movement with American assistance, recruiting Thai students in the United States to work with theUnited States Office of Strategic Services (OSS).[2] The OSS trained Thai personnel for underground activities, and units were readied to infiltrate Thailand.[2] By the end of the war, more than 50,000 Thais had been trained and armed to resist the Japanese by Free Thai members who had been parachuted into the country.[2]
Phibun's alliance with Japan during the early years of war was initially popular.[citation needed] The Royal Thai Army joined Japan'sBurma campaign with the goal of recovering their historical claims to part of theShan states, previously surrendered to theBurmese Empire in theBurmese–Siamese wars and subsequently annexed by the British following theThird Anglo-Burmese War.[citation needed] They gained the return of the four northernmost Malay states lost in theAnglo-Siamese Treaty of 1909, and withJapanese mediation in the Franco–Thai war they also recovered territory lost in theFranco-Siamese crisis of 1893.[citation needed]
However, Japan had stationed 150,000 troops on Thai soil, and as the war dragged on, the Japanese increasingly treated Thailand as a conquered country rather than an ally.[citation needed] Although the United States had not officially declared war, on 26 December 1942, USTenth Air Force bombers based in India launched the first major bombing raid,[3] which damaged targets in Bangkok and elsewhere and caused several thousand casualties.[2] Public opinion, and even more importantly the sympathies of the civilian political elite, moved perceptibly againstPhibun's alliance with Japan.[2]
The Free Thai Movement was supported by BritishForce 136 and the AmericanOSS – both provided valuable intelligence from within Thailand.
In June 1944, Phibun was forced out of office and replaced by the first predominantly civilian government since the1932 coup.[2] Allied bombing raids continued, and a B-29 raid on Bangkok destroyed the two key power plants on 14 April 1945, leaving the city without power and water.[4] Throughout the bombing campaign, the Seri Thai network was effective in broadcasting weather reports to the Allied air forces and in rescuing downed Allied airmen.[5] The new government was headed byKhuang Aphaiwong, a civilian linked politically with conservatives such as Seni.[2] The most influential figure in the regime, however, wasPridi Banomyong (who was serving asRegent of Thailand), whose anti-Japanese views were increasingly attractive to the Thais.[2] In the last year of the war, Allied agents were tacitly given free access by Bangkok.[2] As the war came to an end, Thailand repudiated its wartime agreements with Japan.[2]
Unfortunately, the civilian leaders were unable to achieve unity.[2] After falling-out with Pridi, Khuang was replaced as prime minister by the Regent's nominee, Seni, who had returned to Thailand from his post as leader of the Free Thai movement in Washington.[2] The scramble for power among factions in late 1945 created political divisions among the civilian leaders that destroyed their potential for making a common stand against the resurgent political force of theRoyal Thai Armed Forces in the immediate postwar years.[2]
Postwar accommodations with the Allies also weakened the civilian government.[2] As a result of the contributions made to the Allied war efforts by the Free Thai Movement, the United States, which unlike other Allied countries had never officially been at war with Thailand, refrained from dealing with Thailand as an enemy country in postwar peace negotiations.[2] Before signing a peace treaty, however, the United Kingdom demanded war reparations in the form of rice shipments to Malaya, and France refused to permit admission of Thailand to the United Nations (UN) until the Indochinese areas regained by the Thais during the war were returned to France.[2] TheSoviet Union insisted on the repeal of Thailand's anti-communist legislation.[2]

Many Thais resented the presence of Japanese forces in their country, especially since these soldiers acted more like occupiers than friends. Whenever the opportunity arose to hinder the progress of Japanese war aims, some Thais would do so.
