Stehender Kriegsbefehl - Standing War Orders

        The two partial sets of Standing War Orders below are from different periods of the war.
        The first set, from early 1941, was taken from U-110 when that U-boat was captured on May 9, 1941 in the North Atlantic south of Iceland by the destroyers HMS Bulldog, HMS Broadway and the British corvette HMS Aubretia. 
        The second set, from early 1945, was taken from U-249 after that U-boat surrendered at Portland, England on 9 May 1945.     
        Both translated records are in the custody of the U.K. National Archives at Kew, Richmond Surrey, England.
