At the beginning of the film, Captain Walsh (Reginald Gardiner) announces to a group of folks on a wagon train that he and his cavalry were ordered back to their fort by General Blackwell. These people beg the cavalry to stay, as there are hostile Indians in the region...but he leaves. Not surprisingly, the settlers are soon massacred. The problem is that the General insists he never ordered the Captain back to the fort...and the Captain insists that he did. At a court martial to decide the case, General Blackwell drops dead on the witness stand and no one is able to prove anything...and the General dies with a stain on his record.
After his father's death, Captain Blackwell (Glenn Langan) goes off looking for proof that his father was not responsible for the settlers' deaths. At the same time, unbeknownst to him, his ne'er do well brother, Cash (Victor Mature) is also investigating under cover. Considering Cash is a professional gambler and an embarrassment to the family, he can poke around much better than his brother and soon infiltrates a gang who appear responsible for the massacre...and their toady, Captain Walsh. What's next? See the film.
This is a very good western in many ways. The biggest plus is the plot. About 95% of all westerns have three basic plots....but this one is different. The other big plus is Victor Mature, an A-list actor, starring in the film. Often in the 1950s, Fox and the other studios would usually use B-listers (or C-listers) for westerns and the A-list ones for the prestige pictures. Here, however, you get Mature as well as a pretty good villain (Albert Dekker). All in all, very good...nearly earning a 9.
