Rio Grande

Wayne's Captain York from Fort Apache has become a Colonel by the time Rio Grande closes the Ford cavalry trilogy, but is still much exercised by troubled notions of authority in both the mirrored families of home life (O'Hara and estranged son Jarman) and command (hamstrung by the inconveniently close Mexican border while keeping down marauding Apaches). A bit wordy, a bit plot-heavy, and with an unfortunate tendency to saccharine musical excess (the Sons of the Pioneers), it's fairly minor but still resonant Ford.
