 In August, the two ships laid offensive minefields off the British coast, and "Nautilus" made a similar attempt in October that was cancelled when radio intercepts indicated British naval forces were present.In June 1915, "Albatross" was transferred to the eastern Baltic, where she began to lay offensive minefields.The last of these resulted in the Battle of Åland Islands on 2 July after a group of Russian armored cruisers intercepted "Albatross" and her escorts.
