In the "Black Friday" air attack of World War II a force of Allied Bristol Beaufighter aircraft suffered heavy casualties during an unsuccessful attack on German destroyer Z33 and her escorting vessels on 9 February 1945. The German ships were sheltering in a strong defensive position in Førde Fjord, Norway, forcing the Allied aircraft to attack through heavy anti-aircraft fire. The Beaufighters and their escort of North American P-51 Mustang fighters were also surprised by twelve German Focke-Wulf Fw 190 fighters. In the resulting attack the Allies damaged at least two of the German ships for the loss of seven Beaufighters shot down by flak guns. Another two Beaufighters and one Mustang were destroyed by the Fw 190s. Either four or five German fighters were shot down by the Allied aircraft, including one flown by an ace. Due to the losses suffered in this raid the Allied anti-shipping force adopted new tactics which placed a lower priority on attacking warships. (Full article...)
