We talk with Tim McGrath, author of "Three Roads to Gettysburg: Meade, Lee, Lincoln, and the Battle That Changed the War, the Speech That Changed the Nation." These men came from different parts of the country and very different upbringings: Robert E. Lee, son of the aristocratic and slaveholding South; George Gordon Meade, raised in the industrious, straitlaced North; and Abraham Lincoln, from the rowdy, untamed West.
Tim McGrath is a winner of the Samuel Eliot Morison Award for Naval Literature and two-time winner of the Commodore John Barry Book Award, as well as the author of the critically acclaimed biographies "James Monroe: A Life" and "John Barry: An American Hero in the Age of Sail."
