Built of plywood and measuring 115 feet long, powered by four supercharged petrol engines and armed to the teeth with heavy weapons, the'D' Class Motor Gun Boats (MGBs) and Motor Torpedo Boats (MTBs) were better known as Dog Boats and played havoc with enemy shipping in home and foreign waters. During three years of war they engaged the enemy on more than 350 occasions, sinking and damaging many ships. Dog Boats at War is the authoritative account of operations by the Royal Navy's'D' Class MGBs and MTBs in the Second World War in Home, Mediterranean and Norwegian waters. As well as drawing on official records - both British and German - the author has contacted several hundred Dog Boat veterans whose eye witness accounts add drama to the unfolding story.
