Breaston Prince, Yorkshire Coach Horse Stallion. Yorkshire Coach Horse is an extinct breed. It was created by crossing powerful Cleveland Bays with lighter, faster and more stylish TB's. The goal was to create a strong but stylish carriage horse. YCH was just like that and was much in demand on the heyday of carriage horses. As the cars came to the streets, YCH's and other carriage horses were not used any more. Studbook of YCH was closed in 1936.
