Burma Railway- Forced labour was used in its construction. More than 180,000—possibly many more—Southeast Asian civilian labourers (Romusha) and 60,000 Allied prisoners of war (POWs) worked on the railway. Of these, estimates of Romusha deaths are little more than guesses, but probably about 90,000 died. 12,621 Allied POWs died during the construction. The dead POWs included 6,904 British personnel, 2,802 Australians, 2,782 Dutch, and 133 Americans.
