Q SHIP V S U-BOAT

World War I saw the dawn of widespread submarine warfare. With German U-boats preying on merchant ships a new breed of Royal Navy warship entered service - the Q Ship, disguised as an innocent merchantman but armed with concealed guns. Q ship service was dangerous and required unique training in the arts of deception. The U-boats became wary and took fewer risks, and tactics evolved rapidly in the battle for superiority. Detailing the vessels, technology and tactics of the two sides, this book explores the pioneering years of anti-submarine warfare.
