Sir Charles (foaled 1816) was an American Thoroughbred racehorse and an important sire in the early development of the breed in North America.
Imported into America in 1798 at the advanced age of 21, Diomed proved himself "utterly revolutionary" as a stallion in his new country.
[1][5] After retirement from racing, Sir Charles was purchased by Col. William Ransom Johnson of Chesterfield County, Virginia, who owned the Oaklands plantation on the Appomattox River.
[1] In 1830, Sir Charles headed the American sire list, compiled by pedigree consultant Anne Peters, in the first year for which specific data was available.
In 1830, horses sired by Sir Charles won 38 races, with Bonnets o' Blue being his top earner.
[1] Sir Charles' sire line persisted through Wagner until the end of the century,[8] but he proved most influential through his daughters.
*^ Sir Charles is inbred 4S x 5S to the stallion Herod, meaning that he appears fourth and fifth generation (via Highflyer)^ once each on the sire side of his pedigree.
