This is a b/w outdoor western about a cavalry outfit in 1868 Arizona. It was filmed as a pilot for a 30-minute western series but it wasn't picked up. Zane Grey Theater was picked up instead and it went on to be a long running successful series.
Dewey Martin stars as Lt. Johnny Reardon, commander of G Troop. He leads a cavalry patrol and learns that the supposedly peaceful Apaches are on the warpath. The situations are far flung and the dialogue unbelievable. The resolution of the warpath problem is off the charts unbelievable. Had Cavalry Patrol been picked up as a regular series, the writing would have had to be vastly improved for it to last longer than one season.
The cast is good as there are many familiar face sprinkled in among the troopers and Apaches. Sheb Wooley plays a scout that is quite similar to his Pete Nolan character on Rawhide. Victor Jory and Paul Richards play Apaches.
I just watched this on YouTube on the Forgotten Westerns series. It's worth spending 30 minutes to watch it as a view into what television used to be.
