The Shadow Riders (DVD)(1982)

The Civil War is over and the Traven brothers are going home. But what Mac (Tom Selleck, Quigley Down Under) and Dal (Sam Elliott, Tombstone) find upon their arrival is a town ravaged by Confederate rebels who've refused to surrender. Swearing to fight the Yankees to the bitter end, the guerillas have kidnapped the Travens' younger sisters - as well as Dal's sweetheart, Kate (Katharine Ross, Shenandoah) - and plan to sell them to a brothel in Mexico to raise money for guns and bullets. Determined to rescue their loved ones, Mac and Dal bust their Uncle Black Jack (Oscar(r) winner Ben Johnson, Best Actor in a Supporting Role, the Last Picture Show, 1971) out of prison and head south of the border, where they aim to finish a war they thought had already ended.
