That movie takes place in 1916 and involves Poncho Villa.
TRUE. But it has soldiers capture Rita Hayworth, then take others to the US due to their bravery under fire.
They lose their horses, then find a railroad pushchart, then there is a mutiny against Gary Cooper, the officer taking them to Cordura.
Gary Cooper as the officer, Van Heflin and Tab Hunter as the two “bad guys”.
