At the outbreak of the Second World War in 1939, Harris took command of No. 5 Group RAF in England, and in February 1942 was appointed head of Bomber Command. He retained that position for the rest of the war. In the same year, the British Cabinet agreed to the "area bombing" of German cities. Harris was given the task of implementing Churchill's policy and supported the development of tactics and technology to perform the task more effectively. Harris assisted British Chief of the Air Staff Marshal of the Royal Air Force Charles Portal in carrying out the United Kingdom's most devastating attacks against the German infrastructure and population, including the Bombing of Dresden. After the war Harris moved to South Africa, where he managed the South African Marine Corporation. He was created a baronet in 1953.
