Submarine Shch 212. Penetration, Щ 212. Проход через отсеки

Scsh 212 submarine by Zmeiniy island is visited often. But I ve never seen any decent video about penetration of the wreck. Therefore, I offer you my version of the penetration. I would briefly recall the history of the boat. It left Batumi on December 2, 1942 to the area of Portitskiy arm of the Danube. Last contact to the boat was on 11 December. But It didnt return to the port. Cause of catastrophe it s own torpedoes detonated after the boat bumped on a mine. Подлодку Щ 212, которая лежит около Змеин
