Duel at Diablo (1966)

Lt. Col. Kirby Yorke is posted on the Texas frontier to defend settlers against depredations of marauding Apaches. Col. Yorke is under considerable stress by a serious shortage of troops of his command. Tension is added when Yorke's son (whom he hasn't seen in fifteen years), Trooper Jeff Yorke, is one of 18 recruits sent to the regiment.

When a handful of settlers survive an Apache attack on their wagon train they must put their lives into the hands of Comanche Todd, a white man who has lived with the Comanches most of his life and is wanted for the murder of three men.

The Apache Indians have reluctantly agreed to settle on a US Government approved reservation. Not all the Apaches are able to adapt to the life of corn farmers. One in particular, Geronimo, is restless. Pushed over the edge by broken promises and necessary actions by the government, Geronimo and thirty or so other warriors form an attack team which humiliates the government by evading capture, while reclaiming what is rightfully theirs.

When rancher and single mother of two Maggie Gilkeson sees her teenage daughter, Lily, kidnapped by Apache rebels, she reluctantly accepts the help of her estranged father, Samuel, in tracking down the kidnappers. Along the way, the two must learn to reconcile the past and work together if they are going to have any hope of getting Lily back before she is taken over the border and forced to become a prostitute.

While moving a group of Apaches to a Native American reservation in Arizona, an American scout named Sam Varner is surprised to find a white woman, Sarah Carver, living with the tribe. When Sam learns that she was taken captive by an Indian named Salvaje ten years ago, he attempts to escort Sarah and her half-Native American son to his home in New Mexico. However, it soon becomes clear that Salvaje is hot on their trail.

Owen Thursday sees his new posting to the desolate Fort Apache as a chance to claim the military honour which he believes is rightfully his. Arrogant, obsessed with military form and ultimately self-destructive, he attempts to destroy the Apache chief Cochise after luring him across the border from Mexico, against the advice of his subordinates.

In the mid-19th century, Senator William J. Tadlock leads a group of settlers overland in a quest to start a new settlement in the Western US. Tadlock is a highly principled and demanding taskmaster who is as hard on himself as he is on those who have joined his wagon train. He clashes with one of the new settlers, Lije Evans, who doesn't quite appreciate Tadlock's ways. Along the way, the families must face death and heartbreak and a sampling of frontier justice when one of them accidentally kills a young Indian boy.

Following the surrender of Geronimo, Massai, the last Apache warrior is captured and scheduled for transportation to a Florida reservation. On the way he manages to escape and heads for his homeland to win back his girl and settle down to grow crops. His pursuers have other ideas though.

Two Army officers, an alcoholic ex-Confederate soldier and a womanizing Mexican travel to Mexico on a secret mission to prevent a megalomaniacal ex-Confederate colonel from selling a cache of stolen rifles to a band of murderous Apaches.

A weary gunfighter attempts to settle down with a homestead family, but a smouldering settler and rancher conflict forces him to act.
