One of the very few totally civil war themed movies to come out of any of the Hollywood studios. Ford had long had a reputation as a Civil War buff but had never directed an ACW motion picture. The war had served as a backdrop, or even as a subtext, for his cavalry trilogy and had also figured in the back story of Ethan Edwards in
The Searchers. Subsequently, when the Mirisch Production Company working out of United Artists offered this tale of Grierson's Raid into Mississippi in April 1863 Ford jumped at it.
The original cast was Clark Gable as Marlowe and Wayne as the surgeon Kendall (that would never have worked) with Elizabeth Taylor as Miss Hannah Hunter. But both Gable and Taylor proved unavailable. Wayne was moved to the Marlowe role and Jimmy Stewart was offered the Kendall role but turned it down as he didn't like the character's cynicism. Hence Holden getting the part.
Not all of Ford's stock company were on hand much to the director's bitter disappointment. No Ward Bond or Victor McLaglen, no Ben Johnson or Harry Carey Jr. Judson Pratt, who portrayed Sergeant Major Kirby-Marlowe's "topkick" on the mission- filled the part which had been reserved for McLaglen. But he was nowhere near the blustering, brawling character McLaglen had perfected in the trilogy movies. Nevertheless the standard jokes about drinking written for McLaglen were retained in the script.
The Horse Soldiers is a gutsy cavalry movie that could have been a classic for it contains scenes with the same visual splendour as
Yellow Ribbon but its flawed. A problematical script was rendered irrelevant when Fred Kennedy, one of Ford's favourite stuntmen (he played one of the Yankee soldiers guarding Miss Hannah in the film) was tragically killed on location executing a basic horse fall. It was nobody's fault, but Ford was devastated, he simply wrapped the movie there and then and went home, leaving 20 pages of location shooting unshot.
That's why practically everyone who has viewed the movie felt the ending was too abrupt. Which is a fair comment as the final seven camera shots beyond the battle of the bridge were never filmed.
