Also after the war, the Joint Committee on the Investigation of the Pearl Harbor Attack noted that Army/Navy signals intelligence was “some of the finest intelligence available in our history” and that it “contributed enormously to the defeat of the enemy, greatly shortening the war, and saving many thousands of lives.” Major General Stephen Chamberlin, who served in the Pacific, announced that military intelligence, most of which came from code breaking, “saved us many thousands of lives” in the Pacific theater alone, “and shortened the war by no less than two years.”
