Silent Victory Submarine Warfare in WWII (2010)
This World War II documentary rests on an unusual thesis: it argues that, in the wake of Pearl Harbor, the actions precipitated by the U.S.A.F. that truly helped turn the tide were perpetrated not by the widely-ballyhooed U.S.N. aviators or aircraft carriers, but by the American submarines - silent warriors beneath the deceptively placid ocean surface. The subs, after all, were responsible for gravely wounding Japan's industry, all but destroying the Japanese merchant fleet, and therefore preventing reinforcement of Japanese military garrisons. In relaying this story, the program draws on a series of interviews with military veterans, and endless archival footage of naval battles that chronologically tells the gripping story of the Pacific Front of the war.
