The Ardennes workhorse (Equus ferus caballus) is one of the oldest French breeds of draft horses. It is said to be the descendant of an extinct subspecies called the forest horse (Equus caballus germanicus), which is related to the Solutré horse. The Ardennes breed was already mentioned by Julius Caesar, who appreciated it for its docility. It was later crossed with the Percheron breed to make a more slender horse. This interbreeding is the one most often used as a workhorse in France. The Maison Marguet champagne estate in Ambonnay owns four who have been working in its plots since 2010.
