Longstreet and Lee met on the Gettysburg battlefield
A group of Virginians, led by Jubal A. Early, fabricated charges that Longstreet failed to execute Lee's alleged order to attack at dawn on July 2, 1863, thereby costing the Confederates the victory at Gettysburg.
Longstreet was instructed by Lee to order Major General George E. Pickett to be on the battlefield at daylight
Robert E. Lee countermands James Longstreet's efforts to maneuver around the Union left flank at Gettysburg. Instead, Lee orders Longstreet to attack the Union center. Pickett's Charge is a failure.
With the spring of 1864, Longstreet and his command returned to Virginia. On the morning of May 6, as the right wing of Lee’s army streamed rearward before a massive Union assault, Longstreet’s veterans arrived on the Wilderness battlefield
Lee's surrender ended Longstreet's military career.
James died in the battle of Gettysburg. First he got shot in his throat but lived, then he got wounded in his leg and they had to amputate it. A few weeks later, he died.
