The term rouncey (also spelt rouncy or rounsey) was used during the Middle Ages to refer to an ordinary, all-purpose horse.
The horse, which was also referred to as runcinus, is believed to be a harrowing animal on account of its proportions found in the demesne stock listing before it became an exclusively riding animal.
[2] While the destrier is the most well-known warhorse of the Medieval era, it was the least common, and coursers were often preferred for battle.
[3][4] Sometimes the expected nature of warfare dictated the choice of horse; when a summons to war was sent out in England in 1327, it expressly requested rounceys, for swift pursuit, rather than destriers.
[5] Small sized rounceys were also preferred by mounted archers.
