Prince Regent (foaled 1935) was an Irish Thoroughbred racehorse who won the 1946 Cheltenham Gold Cup. He was the dominant steeplechaser in Ireland during World War II with his wins including the Irish Grand National in 1942. After the war he was able to compete in the major British chases and won the Cheltenham Gold Cup in 1946. He finished third when favourite for the 1946 Grand National and fourth in the race in 1947, carrying top weight on both occasions. He continued to race until the age of fourteen, retiring in 1949. Background Prince Regent was a large bay gelding, standing 17 hands high in maturity, bred in Ireland by A H Mawell. He was sired by My Prince, a high-class performer on the flat who became a very successful sire of National Hunt horses. His other offspring included the Cheltenham Gold Cup winner Easter Hero and the Grand National winners Reynoldstown, Gregalach and Royal Mail. Prince Regent's dam, Nemaea, was a full-sister to Diomedes, an outstanding sprinter who won the Nunthorpe Stakes, King's Stand Stakes and two July Cups. As a yearling, Prince Regent was sold at the Goff's sale and returned to the auction ring a year later when he was bought for £407 by Harry Bonner acting on behalf of James Voase "Jimmy" Rank (the older brother of the film producer J. Arthur Rank). The horse was broken in by Tom Dreaper in Ireland, after which it was intended that he would be sent into training with Gwyn Evans at Druid's Lodge in Wiltshire. When Evans died, Prince Regent was sent back to Dreaper, a livestock farmer who trained racehorses at Greenogue in County Dublin. Rank wanted Dreaper to train for him in England but Dreaper refused to relocate. Racing career Early career in Ireland Prince Regent began his racing career in bumpers, winning at the third attempt as a five-year-old in 1940. He then switched to racing over obstacles and developed into a top class steeplechaser over the next two years. In 1942 he won three chases under big weights and was assigned 175 pounds for the Irish Grand National at Fairyhouse. Ridden by Timmy Hyde, he won from Dorothy Paget's Golden Jack. A whole generation of fine Irish chasers, normally exported, ran against each other often in handicaps for small prize money. Prince Regent won 12 races in Ireland between 1941 and 1945. It
