Commonwealth Air Training Plan Brooke-Popham rejoined the RAF shortly after his return to Great Britain and only weeks after the outbreak of the Second World War. He was first appointed as head of the RAF's training mission to
Canada making him responsible for defence matters in
Singapore,
Malaya,
Burma and
Hong Kong. This was a considerably more demanding undertaking than any of Brooke-Popham's many previous appointments. The
Command was new and Brooke-Popham was the first RAF officer to be appointed Commander-in-Chief of a joint command during a world war. Although it had been agreed in London that Brooke-Popham should be replaced as commander-in-chief on 1 November 1941, the change was not made because of the critical situation. With the war with Japan now unfolding, many believed that Brooke-Popham was near to a nervous collapse. The cabinet envoy Duff Cooper urged his replacement and London agreed. On 27 December, at the height of the
Battle of Malaya, Brooke-Popham handed over command to
Lieutenant-General Sir
Henry Pownall. Brooke-Popham's return to Britain was closely followed by the
fall of Singapore on 15 February 1942. Inevitably, Brooke-Popham was associated with the collapse and he was publicly attacked by some in Britain as the man chiefly responsible for the defeat.
Later war years In May 1942, Brooke-Popham retired from active service in the RAF for the second time. His reputation severely damaged by the events in the Far East, he nevertheless continued to serve where he could. At some stage in 1942, Brooke-Popham became Inspector-General of the
Air Training Corps, a position he held until 1945. From 1944 to 1946, he served as President of the
Navy, Army and Air Force Institutes Council. ==Later years==
