Pound for pound, the Patrol Torpedo (PT) boats were WWII's most heavily armed fighting boats. Screwed and glued together on a hull made of wood, these 50 tons of fast fighting fury were hated by the Japanese who nicknamed them "The Devil Boats of the Night". With their three powerful marine engines and speedboat designs, they took on the enemy at close quarters with greater frequency than any other type of surface craft--from firefights with coastal barges to protecting the invasion fleet at D-Day. And they attacked the enemy from the freezing seas of the Aleutian Islands to the treacherous waters of the South Pacific. Using unique archive film, reenactments, and extraordinary interviews, here is the story of how this wooden wonder struggled for early recognition, but through the brilliance of its design, daring of its missions, and courage and sacrifice of its crews would play a major part in WWII.
