Originally, the award of the Boundary Commission was to be made public on 13 August. But Mountbatten was reluctant to make this public. According to Philip Ziegler, the author of Mountbatten's official biography, the case of the Chittagong Hill Tracts was uppermost in Mountbatten's mind. "He (Mountbatten) foresaw an Independence Day marred by rancour, Nehru boycotting the ceremonies, India born in an atmosphere not of euphoria but of angry resentment. So Mountbatten decided to announce the award only on 16 August when the celebrations were over. As Zeigler writes, "India's indignation at the award of the Chittagong Hill Tracts to Pakistan may have been a factor in making up Mountbatten's mind to keep the reports to himself till after independence".
Mountbatten was himself surprised by the ferocity of Sardar Patel's reaction to the issue. In his memoirs he wrote: "The one man I had regarded as a real statesman with both his feet firmly on the ground, and a man of honour whose word was his bond, had turned out to be as hysterical as the rest. Candidly I was amazed that such a terrific crisis should have blown up over so small a matter. However, I have been long enough in India to realise that major crises are by no means confined to big matters." Leonard Mosley in his book The Last Days of the British Raj puts it "This is a matter for Mountbatten's conscience.
During the 1970s and 80s, there were attempts by the Government to resettle the area with Bengali people. These attempts were resisted by the tribals, who, with the latent support of neighbouring India, formed a guerilla force called Shanti Bahini. As a result of the tribal resistance movement, successive governments turned the Hill Tracts into a militarised zone. Professor Bernard Nietschmann wrote a letter about Shanti Bahini and the Chittagong Hill Tracts people to the editor of the New York Times by published on October 25, 1986 (archived by the Fourth World Documentation Project) at the Center for World Indigenous Studies website.
It was they who said it, not Bangladesh government (mind you).
