James Longstreet (January 8, 1821 – January 2, 1904) was an American soldier and diplomat. He was one of the foremost Confederate generals of the American Civil War and the principal subordinate to General Robert E. Lee, who called him his "Old War Horse". He served under Lee as a corps commander for most of the battles fought by the Army of Northern Virginia in the Eastern Theater, and briefly with Braxton Bragg in the Army of Tennessee in the Western Theater.
