America: The Story of Us, Vol. 3 - Civil War/Heartland

"This documentary examines the evolution of America from the viewpoints of the men and women -- some famous, some little-known -- whose innovation and ingenuity helped mold the country into something truly unique. Among these innovations include the creation of the transcontinental railroads, supply lines, and telegrams that became valuable weapons in the Civil War, and were largely responsible for transforming the American heartland."
