The Battle of Gettysburg exerts a unique hold on the national imagination. Many writers have argued that it represented the turning point of the Civil War, after which Confederate fortunes moved inexorably toward defeat. Successive generations of historians have not exhausted the topic of leadership at Gettysburg, especially with regard to the first day of the battle. Often overshadowed by more famous events on the second and third days, the initial phase of the contest offers the most interesting problems of leadership, including Lee's strategy and tactics, the conduct of Confederate corps commanders Richard S. Ewell and A.P. Hill, Oliver Otis Howard's role on the Union side, and a series of notable debacles among Lee's brigadiers. Drawing on a range of sources, the contributors combine interpretation and fresh evidence that should challenge students of the battle, Civil War buffs, and military historians to reconsider their understanding of the events of July 1, 1863.
