Wheels of Thunder (An Adventure Novel of the Mexican Revolution)

When Mexican revolutionary Pancho Villa swore to bring his people out of slavery and into the 20th Century, he didn't reckon on having a Hollywood film crew in on the action. But now that is the price he must pay for the guns and ammunition he needs to fight the most savage battle of the war... and for the services of the men who will get them. The Gringos. The four hardest hombres south of the Rio Grande.
