 Kenney sent home Major General Royce , Brigadier Generals Edwin S. Perrin , Albert Sneed and Martin Scanlon , and about forty colonels . In Australia he found two talented , recently arrived brigadier generals , Ennis Whitehead and Kenneth Walker . Kenney reorganised his command in August , appointing Whitehead as commander of the V Fighter Command and Walker as commander of the V Bomber Command . Allied Air Forces was composed of both USAAF and RAAF personnel , and Kenney moved to separate them . Brigadier General Donald Wilson arrived in September and replaced Air Vice Marshal Bostock as Kenney 's chief of staff , while Bostock took over the newly created RAAF Command . Walker was shot down over Rabaul in January 1943 . His successor , Brigadier General Howard Ramey , disappeared in March 1943 .
