James Ewell Brown "Jeb" Stuart

James Ewell Brown "Jeb" Stuart (February 6, 1833 – May 12, 1864) was a United States Army officer from Virginia who became a Confederate States Army general during the American Civil War. He was known to his friends as "Jeb,” from the initials of his given names. Stuart was a cavalry commander known for his mastery of reconnaissance and the use of cavalry in support of offensive operations. While he cultivated a cavalier image (red-lined gray cape, the yellow waist sash of a regular cavalry officer, hat cocked to the side with an ostrich plume, red flower in his lapel, often sporting cologne), his serious work made him the trusted eyes and ears of Robert E. Lee's army and inspired Southern morale.
Stuart graduated from West Point in 1854, and served in Texas and Kansas with the U.S. Army. Stuart was a veteran of the frontier conflicts with Native Americans and the violence of Bleeding Kansas, and he participated in the capture of John Brown at Harpers Ferry. He resigned his commission when his home state of Virginia seceded, to serve in the Confederate Army, first under Stonewall Jackson in the Shenandoah Valley, but then in increasingly important cavalry commands of the Army of Northern Virginia, playing a role in all of that army's campaigns until his death.
Stuart was mortally wounded at the The Battle of Yellow Tavern occurred May 11, 1864 dying the next day.
