No. 428 Squadron RCAF
On 7 Nov 1942, he assumed command of No 428 (RCAF) Squadron, standing up the squadron in No. 4 Group. As the OC, it was noted that "Wing Commander Earle was a grand chap, one who can genuinely be called, 'One of Nature's Gentlemen'. He was well liked by the Canadians and sadly missed when he left on promotion to group captain in February 1943. He flew two operations from Dalton, occupying the astro-dome. He had previously been flying Fairey Gordons in the Middle East (Iraq), and found the Wellington difficult, partly due to his eyesight not liking the English skies, and partly as he was not a tall man." After only three months, he left 428 Bomber Squadron (RCAF) as an acting group captain on 7 Feb 1943, when he was assigned as the station commander of RAF Ridgewell and then RAF West Wickham, late in 1943, then as a temporary group captain. He ended the war as Air Officer Commanding No. 300 Group RAF (RAF Transport Command) in Australia.
No. 222 Squadron RAF
The squadron was formally formed at Thasos on 1 April 1918 from "A" Squadron of the former No. 2 Wing, RNAS when the Royal Air Force was formed. At this time, Richard Peirse became Officer Commanding 222 Squadron. Later, on 6 April 1918, former "Z" Squadron of No. 2 Wing, RNAS was added to the strength. Renumbered No. 62 Wing and consisting of Nos. 478, 479 and 480 Flights, the squadron was given the task of maintaining raids on Turkish targets in Macedonia and Thrace, operating from islands in the Northern Aegean, officially adopting the 222 Squadron number plate on 14 September 1918. The squadron continued to carry out raids on Turkish targets in the Balkans until the end of the war, eventually disbanding on 27 February 1919.
