In July 1863 the invading Army of Northern Virginia, confident from its victory at Chancellorsville, unexpectedly encountered the Army of the Potomac, still without a general Lincoln could trust, at a small town in Pennsylvania. And there, among the verdant hills, rich fields, and sparkling brooks around Gettysburg, the two armies slaughtered each other in fearful numbers.

«My Enemy, My Brother» is a remarkable re-creation of that battle, told not as military strategists have told it, but the way soldiers, doctors, shopkeepers, farmers, and wives lived it. Drawn from the letters, diaries, and memoirs of the people at Gettysburg, Persico's powerful work chronicles the passions and beliefs, the day-to-day routines, the pain and the terror of those caught up in the epic conflict that, for thousands, became their last role on earth.
