Gun Smoke at Powder River — Patrick Andrews

Outnumbered hundreds-to-one in a Montana wilderness, U.S. Army Captain Charles Riker must lead his band across long miles of open country to the nearest army post at Tongue River. But between them and the fort ride fierce warriors aiming to add bluecoat scalps on to the tribal lodge poles. Short on rations, but long on determination and guts, Riker's column begins its hell trek to freedom while hundreds of Plains Indians close in for the kill.
