My late father was a war buff. I guess it made sense, considering he served in the Navy in World War II, and he had an interest in a lot of war movies.
In 1952, NBC launched a Sunday afternoon series, Victory at Sea, which chronicled over 26 weeks the Allied effort on the seas in WWII. Leonard Graves narrated.
Yes, folks, it was a finite series, not meant to be renewed, but it did resurface years later, airing on some PBS stations, which is how I came across it.
