Operation Wunderland

Operation Wunderland () comprised a large-scale operation undertaken in summer 1942 by the German "Kriegsmarine" in the waters of the Northern Sea Route close to the Arctic Ocean. The Germans knew that many ships of the Soviet Navy had sought refuge in the Kara Sea because of the protection that its ice pack provided during 10 months of the year.
History.
On 16 August 1942, —under Kommodore Wilhelm Meendsen-Bohlken—left Narvik and entered the Barents Sea. Along with it went U-boats , commanded by Captain Grau, and , commanded by Lieutenant Captain Timm, as well as destroyers , and .
Kara Sea.
By 19 August, the German fleet rounded Cape Zhelaniya and entered the Kara Sea which was fairly free from ice during the short summer. The next day, the Arado Ar 196 seaplane on board "Admiral Scheer" flew to Kravkova Island in the Mona Islands and spotted three groups of Soviet ships, including icebreakers and . Fog and ice floes prevented the German warships from approaching. When they arrived at the Mona Islands, the Russian ships were gone. "Admiral Scheer" then turned northeast and sped towards the Nordenskiöld Archipelago.
On 24 August, "U-601" sank the Soviet steamer "Kuybyshev" (2,332 BRT). On 25 August, "Admiral Scheer" fell upon the Russian icebreaker (under the command of Captain Anatoli Kacharava) right off the northwest coast of Russky Island at the northern end of the Nordenskiöld Archipelago. After putting up resistance, "Sibiryakov" was sunk in an unequal battle.
"Admiral Scheer" headed back to the Mona Islands, but not finding any ships, sailed again to the Nordenskiöld Archipelago, trying to straddle the two convoy routes from the Vilkitsky Strait. Since it was unable to find any Soviet ships, "Admiral Scheer" headed southeast towards Dikson Island in order to attack its military installations. Its powerful guns caused random destruction ashore at Dikson and badly damaged the ships and "Revolutsioner" anchored in the harbour. On 30 August, "Admiral Scheer" returned to Narvik.
On 8 September, "U-251" surfaced close to Uyedineniya Island and destroyed a Soviet weather station with gunfire.
Barents Sea.
During the operation, (Lt. Captain Brodda) sank, on 17 August, a transport convoy of the Soviet Secret Service (NKVD) composed of cargo ships "Nord" and "Komsomolets" and light vessels "Sh-III" and "P-IV" west of the Yugorsky Strait. Apparently there were 328 political prisoners on board, of which 305 men were killed through artillery fire or drowning. Meanwhile, on 20 August, (Lt. Captain Max-Martin Teichert) tried to sink the Soviet icebreaker off Belushya Guba with torpedoes but was unsuccessful. and "U-209" emerged and bombarded Soviet targets in Cape Zhelaniya and Khodovarikha on 25 and 28 August respectively.
Conclusion.
Operation Wunderland was only moderately successful. Owing to adverse weather conditions and the abundance of ice floes, the vessels taking part in Operation Wunderland did not venture beyond the Vilkitsky Strait. Therefore, the "Kriegsmarine" campaign only affected the Barents Sea and the Kara Sea. By mid-September it had to be stopped because of the freezing of the sea surface with thick pack-ice, especially in the Kara Sea, which not being affected by the warmer Atlantic currents freezes much earlier.
