2nd.ed., 1924. Xiv + 268 pp., frontis., + 45 other photo-plates. Fawn cloth ; black lettering. 19 x 13cm. Some foxing o/w V.G. First published in 1920, this is the story behind a branch of the Royal Navy during the First World War of which the public knew little. The author describes the operations of the Q-ships RESULT and TAYNE, the steam yachts ZAREFAH and SAGITTA, and various armed smacks and hydrophone trawlers. These vessels quietly and secretly went about the business of making safe German mines, hunting U-boats, and capturing or destroying enemy surface ships. The author (famous for his circumnavigation in the yawl AMARYLLIS ) served in this branch of the Navy during 1917 and 1918.
