The Wild Bunch movie

A few months before World War I, an aging band of outlaws led by Pike Bishop rob a Texas bank intent on using the money to retire. When the robbery goes wrong, the gang is forced to flee to Mexico with Bishops reformed ex-partner, Deke Thornton, in hot pursuit. With nothing to show for the failed robbery, Bishops gang agrees to steal a shipment of guns for General Mapache Juerta, to restore their fortunes. With Thornton closing in, and their association with the evil Juerta trying their conscience, Bishop and co. prepare for their lawless past to catch up with them.
