"Gary Gallagher dissects art and cinema with a historian's eye and the heart of a 14-year-old watching Shenandoah three times in a row. In crisp and compelling prose, he shows that winners don't always write the history. More than 140 years after Appomattox, the cause of the Union is still missing in action on the screen and canvas. This book is a must-read for anyone who cares about the power of popular culture to shape memory of the past."--Tony Horwitz, author of Confederates in the Attic.
