At the outset of the Korean War the CIA still only had a few thousand employees, around one thousand of whom worked in analysis. Intelligence primarily came from the Office of Reports and Estimates, which drew its reports from a daily take of State Department telegrams, military dispatches, and other public documents. The CIA still lacked its intelligence-gathering abilities. On August 21, 1950, shortly after, Truman announced Walter Bedell Smith as the new Director of the CIA. The change in leadership was took place shortly after the invasion of South Korea, as the lack of a clear warning to the President and National Security Council about the impending North Korean invasion was seen as a grave failure of Intelligence.
