Rösselsprung was a plan by the German Kriegsmarine to intercept an Arctic convoy in mid-1942. It was the German Navy's largest operation of its type and arguably the most successful since it resulted in the near-destruction of Convoy PQ 17. Ironically, that success was entirely indirect, as no Rösselsprung ship caught sight of the convoy or fired a shot at it. PQ 17's losses were instead caused by U-boat and aircraft attacks. Despite not making contact with the convoy a number of the Rösselsprung ships were damaged in the course of the operation, notably the heavy cruiser Lützow, which ran aground in thick fog and needed three months of repairs.
Background
The name Rösselsprung refers to the Knight’s Move in Chess. It was an attempt to intercept the arctic convoy expected in late June 1942, which would be Convoy PQ 17. Two naval forces were assembled and held in readiness: the first, at Trondheim, comprised the battleship Tirpitz, the heavy cruiser Admiral Hipper and six destroyers under the command of Admiral Otto Schniewind; the second, at Narvik, was composed of the heavy cruisers Lützow and Admiral Scheer and six destroyers under the command of Vice-Admiral Oskar Kummetz.
A patrol line of U-boats was established in the
Rösselsprung was handicapped by complex command arrangements, with authority to go at each stage resting with Hitler and a contradictory mission statement; the forces were instructed to attack and destroy the convoy but also to avoid any action that would lead to damage to the capital ships, particularly Tirpitz.
Action
PQ 17 left Hvalfjörður on 27 June 1942 but it was not detected by the advance patrol. No warning of PQ 17 was raised until 1 July, when it was spotted by U-456 of Eisteufel; by this time the convoy was already past Jan Mayen Island, and was closing with QP 13.
With the complex decision-making process binding Rösselsprung, no move was made until 2 July; Tirpitz, Hipper and four destroyers left Trondheim at 20:00 on 2 July, while Lutzow and Scheer with their five destroyers left Narvik at 12:30 on 3 July. The journeys were taken through channels between the Norwegian Islands and the main coastline, sometimes known as
The northwards move by Tirpitz and Hipper had been detected by Allied Intelligence and the
The German naval signals intelligence service (B-Dienst) quickly realized that the convoy was scattering and Schniewind requested permission to sortie. Again, the extended chain of command hindered movement, permission not being received until 15:00 on 5 July and then only with the caveat to avoid action with the British capital ships. The U-boats of Eisteufel were instructed to leave the attack on the convoy ships to concentrate on finding and attacking the Home Fleet, particularly the carrier HMS Victorious.
At 15:00, the flotilla, now consisting of Tirpitz, Hipper and Scheer, with seven destroyers and two torpedo boats, left Altenfjord and headed north-west toward the ships of PQ 17. Almost immediately, they were sighted by the
Both sighting reports were detected by B-Dienst and at 21:30, Erich Raeder, concerned that the fleet was steaming into a trap, ordered a recall just six hours after it had sailed.
Conclusion
Despite indirectly causing the catastrophic losses to PQ 17, the Rösselsprung operation was a disappointing performance by the German capital ships. Also, Tirpitz,[why?] Lutzow and the three destroyers spent a considerable time in dock for repairs. That made the Kriegsmarine unable to mount such an extensive operation again in the Arctic campaign, and it never saw a comparable naval success.
