This is a very good story that was made into a very compelling western by director David Butler from James Warner Bellah's novel "rear guard". Samule Fuller and Russell S. Hughes get credit for the tau and only occasionally glossy screenplay. Star Guy Madion made several estimable and well-remembered westerns in the 1950s, in which decade he also starred in the "Wild Bill Hickick" TV series along with Andy Devine. The intriguing part of this standard story-line which concerns a ranking officer having to assume leadership of a cavalry outfit after the death of its senior officer is that this man happens to be a medical Captain, not a field commander. They fall in with a wagon train during Indian troubles, and end up meeting infantry as well, whom his second, powerfully played by James Whitmore, refers to as "stinkin' beetle crushers". Madson assumes command of both groups, romances lovely and talented Joan Weldon, and nurses the wagon train through sickness and danger; then, at the last, he gets the inspiration to mount cannon onto the wagons, form a hollow square, and draw the Indians into an ambush. Thus, he uses his imagination to defeat the Indian's long-delayed final attack. Madison gets Weldon, Whitmore's honor as a cavalrymen is served, and all ends well; but there are good dialogue confrontations and strong situations along the way, plenty of battle action and unusually strong character revelations. Music was supplied for this film by veteran Dimitri Tiomkin, costumes by Moss Mabry. The fine cinematography was the work of Wilfrid M. Cline. In the professional cast along with Madison, Whitmore and Weldon were Carl Benton Reid, Harvey Lembeck, Ray Teal, Robert Nichols, Gregg Barton, Renata Vanni, Zacharias Yaconelli, Jim Bannon and others. This is a quality production and a very strong story line which has to do with being true to values as its general themes. It is exceptionally well- carried-out, I suggest and thoughtful, not just for a western but for any genre of film.
