Failures of intelligence contributed in large part to the surrender of Pakistan's Military in Dec 1971 Indo-Pakistan War. From the chronology of the events, it would seem that there was an acute shortage of "strategic intelligence". Strategic intelligence would only focus on the bigger picture, the overall scenario. Intelligence failed in providing the high command with the real intentions of India, the imminence of a war and whether the decisive battles would be fought in the east or the west. The importance of strategic intelligence can be judged from the fact that force deployments are done based on it.
Here, however, we would consider a case of tactical intelligence failure (with strategic consequences in this case).
