Franz Waxman
Did anyone notice that Franz Waxman scored "The Raid"? Other than Bernard Herrmann (who had a decades-long relationship with CBS), Waxman appears to be the only film composer who scored a Gunsmoke episode. He passed on a year later.
Waxman is one of the great film composers. Though he scored many major films, he's probably best-remembered for Bride of Frankenstein and Sunset Blvd..
At the end of part 1, as the bad'uns are riding off, the music strongly resembles (rhythmically, at least) "The Ride from Dubna" cue from Waxman's score to Taras Bulba.
