During the Civil War, the Union Army had an increasing supply of something the Confederacy lacked: food. Canning operations in the North kept the Union’s bellies full while Southern soldiers faced starvation. In his new book, “Starving the South: How the North Won the Civil War” (St. Martin’s Press/2011), author and culinary historian Andrew F. Smith explores the role of food in the outcome of the war. Smith joins host Frank Stasio to talk about his research and the connection between the Civil War and the industrialization of America’s food supply.
