Thakins Than Tun and Soe, while in Insein prison in July 1941, had co-authored the "Insein Manifesto" which, against the prevailing opinion in the Dobama movement, identified world fascism as the main enemy in the coming war and called for temporary co-operation with the British in a broad allied coalition which should include the Soviet Union. Soe had already gone underground to organise resistance against the Japanese occupation, and Than Tun was able to pass on Japanese intelligence to Soe, while other Communist leaders Thakins Thein Pe and Tin Shwe made contact with the exiled colonial government in Simla, India.
