The air war in mid-April 1941 in Greece

Initially the German air force concentrated its efforts against Yugoslavia and Eastern Macedonia. As they became accustomed to moving their support and aircraft, they increasingly devoted effort to hitting British positions and the road system in the rear. The RAF was outnumbered and while they did their best to counteract the German air superiority, they suffered great losses. In one case, on 15 April, the Germans hit Niamata airfield and destroyed all ten Blenheims on the ground. The improving weather simply aggravated the situation. While the day seemed like one continuous air attack from strafing German fighters, actual losses on the ground proved to be quite light. This is based on the account in Vol.II of the Official History.
