The destrier is the best-known war horse of the medieval era. It carried knights in battles, tournaments, and jousts. It was described by contemporary sources as the Great Horse, due to its significance. While highly prized by knights and men-at-arms, the destrier was not very common. Most knights and mounted men-at-arms rode other war horses, such as coursers and rounceys. These three types of horse were often referred to generically as chargers.
