What is "tent pegging"

Tent pegging (sometimes spelled tent-pegging or tentpegging) is a cavalry sport of ancient origin, and is one of only ten equestrian disciplines officially recognised by the International Equestrian Federation. Used narrowly, the term refers to a specific mounted game with ground targets. More broadly, it refers to the entire class of mounted cavalry games involving edged weapons on horseback, for which the term "equestrian skill-at-arms" is also used.
