"The final Russian mining operations for the year produced mixed results. On the early morning of 6 December [1915], five cruisers, covered by the Petropavlovsk and Gangut, laid a minefield halfway between Hela and the southern tip of Gotland. The Russian success at radio interception enabled them to avoid a German minelaying expedition at work off Lyserort the same night. However, only the small cruiser Lübeck was damaged by the Russian field on 13 January. The far less ambitious operation in which three destroyers laid mines between Windau and Lyserort on the night of 15 December was more productive. The next morning the German cruiser Bremen and destroyer V.191 were sunk in the field, which also claimed on the 23d the destroyer S.177 and auxiliary patrol boat Freya."
In 1915 the Russian fleet more than held its own against the German in the Baltic Sea, securing its coast with mines.
