The Sch-311 Kumzha is laid on 06.11.1933 at Krasnoe Sormovo shipyard in Gorkyi (Nizhniy Novgorod). The ship is officially named as Sch-311 in 15th September 1934. It is launched 10th April 1935 and moved to Leningrad for armament. The ship is finally commissioned 21st August 1936.
Sch-311 is the most successful Soviet submarine during the Winter War. Commander Fedor Vershinin makes one combat mission, sinking two merchant ships and damaging one. Vershinin receives the Hero of the Soviet Union award, the highest distinction of the time.
Kumzha is awarded the Order of the Red Banner. It is the highest recognition available for a military unit.
In the beginning of the Continuation War, Kumzha completes three short battle missions under Commander Petr Sidorenko. It only manages to cause damages to a single enemy vessel.
Kumzha returns to Leningrad 26th November 1941. It is scheduled to have major changes made over the winter, including new diesel engines. While being repaired, Sch-311 is appointed a new captain, lieutenant commander Anisim Pudyakov.
The Finnish listening station on Kallbåda records under water explosions on 14th September 1942. Lieutenant Erkki Palosuo’s Tupolev SB-10 naval bomber is soon sent to find the cause.
Meanwhile on the Gulf of Finland, the Sch-311 submarine crew is working desperately. Their boat has hit German anti-submarine mines. The explosions have not been powerful enough to sink the submersible, but they have caused considerable damage. The boat is totally exposed.
Palosuo’s bomber reaches the area. Machine gunner Kalle Ahvensalmi soon spots a submarine, which is making an emergency dive. Palosuo drops the depth charges, presumably sinking the submarine.
