Liberty Convoy (2001, WWII Documentary)

Relive the terror of being hunted by German U-boats and see how these "one-off" supply ships helped win World War II. They were the primary weapons in the Battle of the Atlantic. But they weren't fighting ships. They were freighters, produced "by the mile and chopped off by the yard" in such numbers that they overwhelmed the forces arrayed to stop them. Using period footage, dramatic re-enactments and interviews with the men who manned the vessels that formed the "bridge of liberty," BATTLE STATIONS tells the remarkable tale of the development and deployment of the humble freighter that delivered victory in World War II. The program goes from the yards where they were built to the dangerous waters where brave crews experienced the terror of being targeted by Nazi wolf packs. The Allied struggle to get enough men and material to the front lines of World War II would have been impossible without the contributions of the "Liberty Convoy".
