IJA committed acts of rape, murder and torture against Muslims in Arakan. During this period, some 22,000 Muslims in Arakan were believed to have crossed the border into Bengal, then part of British India, to escape the violence. The exodus was not restricted to Muslims in Arakan. Thousands of Burmese Indians, Anglo-Burmese and British who settled during the colonial period emigrated en masse to India. To facilitate their reentry into Burma, the British formed Volunteer Forces with Rohingya. Over the three years during which the Allies and Japanese fought over the Mayu peninsula, the Rohingya recruits of the V-Force, engaged in a campaign against Arakanese communities, using weapons provided by V-Force. According to the secretary of the British governor, the V Force, instead of fighting the Japanese, destroyed Buddhist monasteries, pagodas, and houses, and committed atrocities in northern Arakan. The British Army's liaison officer, Anthony Irwin, on the other hand, praised the role of the V Force. Pakistan Movement During the Pakistan Movement in the 1940s, Rohingya Muslims in western Burma organised a separatist movement to merge the region into East Pakistan. The commitments of the British regarding the status of Muslims after the war are not clear. V Force officers like Andrew Irwin felt that Muslims along with other minorities must be rewarded for their loyalty. Muslim leaders believed that the British had promised them a "Muslim National Area" in Maungdaw region. They were also apprehensive of a future Buddhist-dominated government. In 1946, calls were made for annexation of the territory by Pakistan as well as of an independent state. Before the independence of Burma in January 1948, Muslim leaders from Arakan addressed themselves to Muhammad Ali Jinnah, the founder of Pakistan, and asked his assistance in incorporating the Mayu region to Pakistan considering their religious affinity and geographical proximity with East Pakistan. The North Arakan Muslim League was founded in Akyab (modern Sittwe) two months later. The proposal never materialised since it was reportedly turned down by Jinnah, saying that he was not in a position to interfere in Burmese matters. Post-WWII migration The numbers and the extent of post-independence immigration from Bangladesh are subject to controversy and debate. In a 1955 study published by Stanford University, the authors Virginia Thompson and Richard Adloff write, "The post-war (World War II) illegal immigration of Chittagonians into that area was on a vast scale, and in the Maungdaw and Buthidaung
