This well-paced spaghetti western from director Giorgio Ferroni deals with Southern Major Sanders (Jacques Sernas), who continues fighting the North after the conclusion of the Civil War. Former Rebel Gary Diamond (Giuliano Gemma), now a guide, leads a pair of Union soldiers to stop Sanders before he can pull off a raid on Fort Yuma. Little does Diamond know that one of the Union officers is actually Sanders' spy. More complications ensue, pairing Diamond with saloon-girl Connie Breastful (Sophie Daumier) before Sanders' plot is foiled. A rousing melodrama with a labyrinthine storyline, Ferroni's film sometimes crosses the line into silliness, but remains entertaining throughout, aided by a fine score by Ennio Morricone and Gianni Ferrio.
