In the course of my research for my Medieval Warriors series, I learned a lot of surprising things about the horses the Norman knights rode. For example, horses were not so much distinguished by breed as by use. There were highly trained warhorses like destriers, strong coursers, smooth-gaited palfreys for lords and ladies, and general purpose rounceys. Knights did not, for the most part, ride their warhorses around the countryside, at least not very often. They rode palfreys, high-status riding horses.
