ABSTRACT
In 1942–43 a force of possibly 200,000 to 300,000 people, working under the supervision of the Imperial Japanese Army, constructed a railway from Kanchanaburi in western Thailand to Thanbyuzayat on the Andaman Sea coast of Burma (now Myanmar). The purpose of this railway was to provide a supply link between the Gulf of Thailand and Burma, which the Japanese had occupied in early 1942. The sea route via the Straits of Malacca had become unreliable after the Battle of Midway in June 1942 and a new, more secure, overland route was needed to maintain the Japanese armies in Burma as they planned to invade India.
