Why a Confederate General became the most hated man in the post-war South

In short: James Longstreet was Robert E. Lee's trusted Old War Horse, yet he died a pariah. After the Civil War, his support for Republican Reconstruction and his public criticism of Lee's battlefield decisions turned him into a scapegoat for the Lost Cause movement, which blamed his tactical choices for the Confederate defeat.

Born in 1821, James Longstreet was a career soldier who graduated from West Point in 1842, ranking 54th out of 56 cadets. He served with distinction in the Mexican–American War, earning brevet promotions for his bravery at Churubusco and Molino del Rey. Despite his later fame as a Confederate corps commander, his early military life was marked by academic struggles and a reputation as a disciplinary problem, though he formed lifelong bonds with peers like Ulysses S. Grant.

During the Civil War, Longstreet became a pivotal figure in the Army of Northern Virginia. He played a key role in the Seven Days Battles and the victory at Second Bull Run, though his career was punctuated by personal tragedy, including the loss of three children to scarlet fever in early 1862. His most significant friction occurred at the Battle of Gettysburg in 1863, where he openly disagreed with Lee’s tactical approach. This disagreement became the focal point for later critics who sought to absolve Lee of responsibility for the defeat.

Longstreet’s post-war life further alienated him from his former comrades. He joined the Republican Party, cooperated with President Grant, and led African-American militia against the White League in 1874. These actions, combined with his critical writings about Lee, made him anathema to the Southern establishment. While the Lost Cause movement vilified him for decades, modern historians have begun a reassessment, increasingly recognizing him as one of the most gifted tactical commanders of the conflict.
