Indian nationalist leader Subhas Chandra Bose died from third-degree burns on 18 August 1945 after his overloaded Japanese plane crashed in Japanese-occupied Formosa (now Taiwan). However, many among his supporters, especially in Bengal, refused at the time, and have refused since, to believe either the fact or the circumstances of his death. Conspiracy theories appeared within hours of his death and have thereafter had a long shelf life, keeping alive various martial myths about Bose.
During the last week of April 1945, Subhas Chandra Bose along with his senior Indian National Army (INA) officers, several hundred enlisted INA men, and nearly hundred women from the INA's Rani of Jhansi Regiment left Rangoon by road for Moulmein in Burma. Accompanied by Lieutenant General Saburo Isoda, the head of the Japanese-INA liaison organization Hikari Kikan, their Japanese military convoy was able to reach the right bank of the Sittang river, albeit slowly. (See map 1.) However, very few vehicles were able to cross the river because of American strafing runs. Bose and his party walked the remaining 80 miles (130 km) to Moulmein over the next week. Moulmein then was the terminus of the Death Railway, constructed earlier by British, Australian, and Dutch prisoners of war, linking Burma to Siam (now Thailand). At Moulmein, Bose's group was also joined by 500 men from the X-regiment, INA's first guerrilla regiment, who arrived from a different location in Lower Burma.
A year and a half earlier, 16,000 INA men and 100 women had entered Burma from Malaya. Now, less than one tenth that number left the country, arriving in Bangkok during the first week of May. The remaining nine tenths were either killed in action, died from malnutrition or injuries after the battles of Imphal and Kohima. Others were captured by the British, turned themselves in, or simply disappeared. Bose stayed in Bangkok for a month, where soon after his arrival he heard the news of Germany's surrender on May 8. Bose spent the next two months between June and July 1945 in Singapore, and in both places attempted to raise funds for billeting his soldiers or rehabilitating them if they chose to return to civilian life, which most of the women did. In his nightly radio broadcasts, Bose spoke with increasing virulence against Gandhi, who had been released from jail in 1944, and was engaged in talks with British administrators, envoys and Muslim League leaders. Some senior INA officers began to feel frustrated or disillusioned with Bose and to prepare quietly for the arrival of the British and its consequences.
