The Bandera Trail by Ralph Compton

Cowboys on a rescue mission south of the border decide to liberate cattle, too, in this Western adventure from the USA Today–bestselling author.

Set on rescuing their old friend Clay Duval who is trapped inside war-torn Mexico, Gill and Van Austin, nephews of Texas founder Stephen Austin, cross the border after him and soon discover half of Mexico's army wants them dead. Taken prisoner by Santa Anna's soldiers, the brothers make a daring escape and head into Durango country, where they stumble on a valley full of longhorns—and a chance to build a future north of the border. All they have to do now is break Duval out of prison and drive the cattle to safety.

But faced with outlaws, soldiers and the cunning plans of a beautiful woman, the Austins are finding out that this isn't a trail drive, it's a war to reach the Bandera Range alive. And the only way to do it is the Texan way—fighting for every bloody, dusty mile ahead.
