In the Baltic Sea the naval activity had at no time during the first year of the war been great, but during the month of June, 1915, there was a minor naval engagement at the mouth of the Gulf of Riga, during which the Germans lost a transport and the Russians an auxiliary cruiser. In the other northern waters the Germans lost the submarine _U-14_, which was sunk on June 9, 1915. The crew were brought to England as prisoners. Three days later the British admiralty admitted that two torpedo boats, the _No. 10_ and the _No. 12_ had been lost. The loss of two such small boats did not worry Britain as much as did the loss of many merchant ships in the war zone right through the spring and summer of 1915, and to show that British warships were not immune from submarine attack, in spite of the fact that many of the underwater craft of Germany were meeting with disaster, the British cruiser _Roxburgh_ was struck by a torpedo on June 20, 1915, but was able to get away under her own steam. The rest of the month saw small losses to nearly all of the fleets engaged in the war, but none of these were of importance. The twelfth month of the first year of war was not particularly eventful in so far as naval history was concerned. On July 1, 1915, the Germans maneuvered in the Baltic Sea with a small fleet which accompanied transports bearing men who were to try to land on the northern shores of Russia. The port of Windau was the point at which the German bombardment was directed, but Russian torpedo boats and destroyers fought off the invading German fleet--which must have been small--and succeeded in chasing the German mine-layer _Albatross_, making it necessary for her captain to beach her on the Swedish island of Gothland, where the crew was interned on July 2, 1915. On the same, day a German predreadnought battleship, believed to have been the _Pommern_, was sunk at the mouth of Danzig Bay by a torpedo from a British submarine.
