His troops took part in the fierce fighting on Guadalcanal and Harmon was made Vice-Admiral HALSEY’s Deputy. He directed air offensives and in July 1944 was made Commander of USAAF for the whole of the Pacific Ocean area. He introduced the tactic of flying bombers at a low altitude so that they could improve their accuracy in hitting targets.
