Having begun the war as the youngest professor in the Commonwealth, Powell ended it as a brigadier. He was given the promotion to serve on a committee of generals and brigadiers to plan the postwar defence of India: the resulting 470-page report was almost entirely written by Powell. For a few weeks he was the youngest brigadier in the British Army, and he was one of only two men in the entire war to rise from private to brigadier (the other being Fitzroy Maclean). He was offered a regular commission as a brigadier in the Indian Army, and the post of assistant commandant of an Indian officers' training academy, which he declined. He told a colleague that he expected to be head of all military intelligence in "the next war".
