A Distant Trumpet (1964)

In 1883, US Cavalry lieutenant Matthew Hazard, newly graduated from West Point, is assigned to isolated Fort Delivery on the Mexican border of Arizona, where he meets commanding officer Teddy Mainwarring's wife Kitty, whom he later rescues from an Indian attack.

Soon after a new commander, Major General Alexander Quait, takes charge. When his efforts to capture Chiricahua chief War Eagle fail, he orders Hazard into Mexico to cajole the man into surrendering. Hazard convinces War Eagle to return with him with the promise the Indians will be provided a safe haven at a reservation in Arizona. En route to the fort, they encounter Major Miller, who orders the Indians be sent to Florida. Hazard and Quaint journey to Washington, D.C. to request government officials to reverse their decision and allow Hazard to keep his word to War Eagle.
