• Source: Soviet Baltic Sea submarine campaign in 1944

The Soviet submarine Baltic Sea campaign in 1944 was launched by the Soviet Navy to harass enemy shipping and naval military assets of the Nazi Germany on the Eastern Front during World War II.




Background


After the failed offensive of the previous year, Soviets restrained for a further campaign until Finland signed the Moscow Armistice on 9 September 1944, ceasing war with Soviet Union and starting hostilities with Germany (Lapland War). This move, enabled the Soviet Navy to avoid the mine field barrages in the Gulf of Finland that caused heavy losses in 1942 and prevented success in 1943. Submarines ShCh-310, ShCh-318 and ShCh-407 were the first to operate in open Baltic from Finnish harbors and navigating out of the dangerous zones with aid of Finnish naval officers, they were soon followed by other 12 submarines.
On 8 September (before the actual offensive), Soviet submarine M-96 sunk by mine in the Narva Bay. It was the only Soviet submarine loss in 1944.
