Battle of Gettysburg
The nature of the result of the Battle of Gettysburg has been the subject of controversy for years. Although not seen as overwhelmingly significant at the time, particularly since the war continued for almost two years, in retrospect it has often been cited as the "turning point", usually in combination with the fall of Vicksburg the following day. This is based on the observation that after Gettysburg Lee's army conducted no more strategic offensives—his army merely reacted to the initiative of Ulysses S. Grant in 1864 and 1865—and by the speculative viewpoint of the Lost Cause writers that a Confederate victory at Gettysburg might have resulted in the end of the war.
It is currently a widely held view that Gettysburg was a decisive victory for the Union, but the term is considered imprecise. It is inarguable that Lee's offensive on July 3 was turned back decisively and his campaign in Pennsylvania was terminated prematurely (although the Confederates at the time argued that this was a temporary setback and that the goals of the campaign were largely met). However, when the more common definition of "decisive victory" is intended—an indisputable military victory of a battle that determines or significantly influences the ultimate result of a conflict—historians are divided. For example, David J. Eicher called Gettysburg a "strategic loss for the Confederacy" and James M. McPherson wrote that "Lee and his men would go on to earn further laurels. But they never again possessed the power and reputation they carried into Pennsylvania those palmy summer days of 1863."
John Bell Hood
At the Battle of Gettysburg, Longstreet's Corps arrived late on the first day, July 1, 1863. General Lee planned an assault for the second day that would feature Longstreet's Corps attacking northeast up the Emmitsburg Road into the Union left flank. Hood was dissatisfied with his assignment in the assault because it would face difficult terrain in the boulder-strewn area known as the Devil's Den. He requested permission from Longstreet to move around the left flank of the Union army, beyond the mountain known as [Big] Round Top, to strike the Union in their rear area. Longstreet refused permission, citing Lee's orders, despite repeated protests from Hood. Yielding to the inevitable, Hood finally gave in and his division stepped off around 4 p.m. on July 2, but a variety of factors caused it to veer to the east, away from its intended direction, where it would eventually meet with Union forces at Little Round Top. Just as the attack started, however, Hood was the victim of an artillery shell exploding overhead, severely damaging his left arm, which incapacitated him. (Although the arm was not amputated, he was unable to make use of it for the rest of his life.) His ranking brigade commander, Brig. Gen. Evander M. Law, assumed command of the division, but confusion as to orders and command status dissipated the direction and strength of the Confederate attack, significantly affecting the outcome of the battle.
