Dawn on the Great DivideThe Rough Riders--
Buck Jones,
Raymond Hatton and
Rex Bell--endeavor to provide a wagon train safe passage through Indian country. With
Jones heading the caravan and
Bell and
Hatton working undercover, the threesome discover that the "savages" planning to attack the settlers are actually renegade whites. The criminals' target is the shipment of railroad supplies being carried in one of the wagons. Normally, the third "Rough Rider" would have been played by
Colonel Tim McCoy, but when
McCoy was called to active duty in World War II, he was hastily replaced by old-time western star
Rex Bell. Dawn on the Great Divide was the last film for
Buck Jones, who was killed in the infamous Coconut Grove fire shortly before the film was released. ~ Hal Erickson, All Movie Guide
