🔖 Chatterton (1878-1944) was a prolific writer who published around a hundred books, pamphlets and magazine series mainly on maritime and naval themes. At the outbreak of WWI he joined the Royal Naval Volunteer Reserve, leaving the service in 1919 with the rank of Lieutenant Commander. This work first published in 1922 draws on his war experiences and describes the role and exploits of the armed merchant ships designed to lure enemy submarines into making surface attacks, thus giving the Q-ships, as they were known, the opportunity to open fire and sink them. Illustrated with numerous photographs and diagrams.
