I'm currently reading "Warhorse", a fabulous book on the horse as a weapon throughout history. I highly recommend it if you are at all interested in the history of the horse. Like it or not, the horse was used as a war time instrument AND much of our current riding equipment and "traditions" have come from the horses use on battlefields. I am currently reading about the Steppe tribes (Attila the Hun and then later Ghangas Khan). Absolutely fascinating.
On a different note, here is the modern day "Warhorse" for CHAS members.
