The government today refused to make public an Army study on the 1962 war debacle with China, saying the internal report was "top secret" and "extremely sensitive".
Defence Minister A K Antony told the Lok Sabha that the Henderson Brooks Report had "current operational value".
Asked by Congress member Manish Tewari if the report would be made public, the minister replied in the negative.
"Henderson Brooks Report is a TOP SECRET document, based on an internal study by the Indian Army, contents of which are not only extremely sensitive, but are of current operational value," Antony said in a written reply.
However, on the 1947 Indo-Pak war, the Defence Minister said the official historical record had been compiled and it was in the public domain since 1987.
He also said the compilation and publication of other historical records had been taken up subsequently starting with the 1965 war.
However, his statement was silent on whether such an exercise for 1971 Bangladesh Liberation War and the 1999 Kargil War too would be taken up.
