"Although Traveller was General Lee’s favorite horse, Lee did use other horses during the course of the Civil War. When Lee purchased Traveller, his stable already contained two horses, Richmond and Brown-Roan:
Richmond, a bay stallion, was acquired by General Lee in early 1861. The General rode Richmond when he inspected the Richmond defenses. Richmond died in 1862 after the battle of Malvern Hill.
Brown-Roan was purchased by Lee in West Virginia during the first summer of the war. Also referred to as “The Roan,” the horse went blind in 1862 and had to be retired. He was left with a farmer.
Two other horses, Lucy Long and Ajax, joined Lee’s stable after he purchased Traveller:
Lucy Long, a mare, served as the primary backup horse to Traveller. Lucy Long remained with the Lee family after the war. Outliving General Lee, she died when she was thirty-three years old.
Ajax, a sorrel horse, was used infrequently because he was too large for Lee to ride comfortably. Ajax also remained with the Lees after the war. He killed himself in the mid-1860s by accidently running into an iron gate-latch prong."
