The 26 episodes were culled from over 13,000 hours of footage shot by the U.S., British, German and Japanese navies during World War II. Narrated by Leonard Graves and set to a score by Richard Rodgers, this program offered a remarkable look at the realities of naval warfare and the extraordinary challenges faced by the Allies. From U-boat "wolf packs" to the epic battles at Iwo Jima and Okinawa, every major naval engagement of World War II is captured in some of the most riveting combat footage ever shot.
