To help Greece respond to Italian attacks from October 1940, the RAF sent three squadrons of Bristol Blenheims (30, 84 and 211 Squadron) to reinforce the Greek Air Force’s own complement of 12 Mark IV Blenheims. Drawing on first-hand accounts, this study describes the efforts of British and Greek airmen against superior forces (particularly after Germany invaded) up to the fall of Crete in May 1941.
