K-21 danneggia nave da battaglia Tirpitz. Тирпиц.

Western and German sources (and some of the modern Russian sources), states that the K-21 attack was a failure, on contrary of Soviet and some of Russian sources.The final words over the debate will probably never given: it's true that lacks German documents describing the attack, and Germans stated they retreated in fear of still naval British presence. However some details remains true, as the fact that Gestapo tracked and killed the commander Lunin's father for revenge. Reguardless the true results of the attack, the most oustanding result was however a big moral and propaganda victory: the attack was highly praised both by the Soviet and by the Allied press.
