A little know part of 400 Squadron's History was the role its personnel played in the formation of two other squadrons who made up No. 39 (R) Wing, R.C.A.F., in No 83 Group of Second Tactical Air Force.

The three squadrons which comprised this wing all stemmed from the original Canadian overseas air unit, No. 110 (City of Toronto) Army Co-operation Squadron, which arrived in England in February 1940. No. 110 was later redesignated No. 400 and provided a nucleus from which the second R.C.A.F. Army Cooperation Squadron, No. 414, was formed. Nos. 400 and 414 then supplied nuclei for the creation of the third unit, No. 430.

A background article from the Jan-Feb 1966 Sentinel Magazine provides background information on the formation of these Army Cooperation Squadrons. VIEW ARTICLE
