A pictorially vibrant Western classic from John Ford… It is April of 1863. Colonel John Marlowe and three regiments of the Union cavalry set out to ride into the heart of the Confederacy–a 300-mile journey. Their objective is to sever the railroad line to Vicksburg, Mississippi, and thus force that city’s surrender to the Union army. When the mission is completed, Marlowe will have to face the task of leading his men out of the South to safety. Based upon a historical Civil War incident.
