"The Japanese encountered resistance from some indigenous peoples, to be sure, and not only from those ethnic groups and elites that had done relatively well under Western colonial rule. The overwhelming majority of Indians showed no interest in the kind of liberation the Japanese had in mind for them. In the Philippines the peasant Hukbalahap movement waged a guerrilla war against them; in Burma the Karen and Kachin hill tribes also resisted Japanese rule. Nevertheless, the Japanese had no difficulty in finding collaborators among both anti-European nationalists and opportunists. Indian nationalists had not forgotten the 1919 Amritsar Massacre; it was in March 1940 that Udham Singh assassinated Sir Michael O'Dwyer, who had been Lieutenant-Governor of the Punjab at that time. Though the majority of Congress leaders eschewed collaboration with the Japanese - in practice, 'Quit India' meant neutrality, albeit with a great deal of circumlocution - Subhas Chandra Bose enthusiastically hailed 'the end of the British Empire' and called on Indians to join the Axis side. Around 3,500 answered the initial call from Berlin of the self-proclaimed Netaji ('leader') to form an Indian Army of Liberation, most of them Indians who had been taken prisoner by the Germans in North Africa. When he reached Asia - having travelled by U-boat from Kiel to Sumatra - Bose was able to recruit a further 45,000 men (again mostly prisoners from Singapore and elsewhere) to his Indian National Army and the Axis cause."
