Soviet Storm (series...link) War at Sea
 

Stumbled across this series on youtube, it is excellent ended up being watching all 18 episodes (stayed up way too late) lol. The entire series is worth watching (all episodes are on youtube) but sharing this episode as it deals with the war at sea in the Baltic etc. Covers some interesting submarine action.
