In the Black Sea the Russian Fleet has during the
week been active and successful. It destroyed several Turkish coaling-places and also sunk two Turkish steamers. In the Baltic, as we learn from a Petrograd telegram published on Thursday, a Russian submarine met the German Baltic Squadron on Tune 3rd and attacked it, apparently by throwing out mines. These mines are alleged to have achieved their object, as two explosions were heard by the crew of the submarine before it dived. On June 4th a Russian submarine attacked a party of enemy vessels near Windau, and sank a German torpedo-boat and a transport. Another torpedo-boat was also damaged, and another enemy vessel ran on to a Russian mine and was blown up. It is clear that the winter was by no means wasted by the Russian Navy in the Baltic. Not only its numerical force, but its efficiency, is very much greater than at the beginning of the War.
