entire squadron. The commanding officer of the 36 LG was Major Franjo Džal, who watched from the ground as his men were slaughtered in their obsolete biplanes. In an unequal battle against superior adversaries, five aircraft were destroyed while taking off and eight pilots killed. Two more Furies and Bücker Bü 131 were destroyed on the ground. Of the attacking German aircraft, five Bf 109s and two Bf 110s failed to return, though most were non-combat losses, at least one was lost when rammed by a Fury. The other squadron of Yugoslav Furies active at the time of the invasion strafed enemy tanks and ground forces, some being lost to ground fire and one being destroyed in a dogfight with a Fiat CR.42. The rest of the Yugoslav Furies were destroyed when they became unserviceable or at the time of Armistice on 15 April. Ex-RAF Furies were also used by the South African Air Force against the Italian forces in East Africa in 1941 and despite their obsolescence, destroyed two Caproni bombers as well as strafing many airfields, destroying fighters and bombers on the ground. A total of 262 Furies were produced, of which 22 served in Persia, 3 in Portugal, at least 30 in South Africa, 3 in Spain, at least 30 in Yugoslavia and the remainder in the United Kingdom.
