Barding (also spelled bard or barb) is armour for horses. During the late Middle Ages as armour protection for knights became more effective, their mounts became targets. This tactic was effective for the Scots at the Battle of Bannockburn in the 14th century when horses were killed by the infantry, and for the English at the Battle of Crécy in the same century where archers shot horses and heavy infantry killed the French knights after they were dismounted. Barding developed as a response to such events.
Surviving period examples of barding are rare; however, complete sets are on display at the Philadelphia Museum of Art, the Wallace Collection in London, the Royal Armouries in Leeds, and the Metropolitan Museum of Art in New York.
The chanfron (also spelled champion, chamfron, chamfrein, and shaffron) was designed to protect the horse's face. Sometimes this included hinged cheek plates. A decorative feature common to many chanfrons is a rondel with a small spike.
The chanfron was known as early as ancient Greece, but vanished from use in Europe until the twelfth century when metal plates replaced boiled leather as protection for war horses. The basic design of the chanfron remained stable until it became obsolete in the seventeenth century, although late examples are often notable for engraved decoration. A chanfron extended from the horse's ears to its muzzle. Flanges often covered the eyes. In an open chanfron, the eyes received no protection. Hinged extensions to cover the jowls were commonly used for jousting tournaments.
