Lord Charles Somerset was the younger son of the fifth Duke of Beaufort, who had been Master of the Horse. He inherited a love and understanding of horses and a personality which combined arrogance of manner, hatred of opposition, and a certain ruthlessness of method. These qualities enabled him to bring about, within 10 years, a startling improvement in the half-bred Caper and its racing. The one was never again as good after his time; the other not until the 1880s. The History of Horse Racing by Roger Longrigg, page 258.
