In regard to Peter Hooker’s article “Unprepared But Undaunted” (December 2017, pp. 14–17), it should be pointed out that Grand Admiral Erich Raeder’s resignation in January 1943 was due to an event that took place in the Barents Sea. An Allied convoy had sailed from Scotland in late December 1942 bound for Murmansk, escorted by six Royal Navy destroyers and several smaller warships. Advised of its departure, the Kriegsmarine assembled two heavy cruisers (the Lützow and Hipper) and six destroyers to attack the convoy. Adolf Hitler had cautioned Raeder not to risk his heavy units unnecessarily, but the relative weakness of the convoy escort presented an irresistible opportunity.
