Musjid (1856–1865) was a British Thoroughbred racehorse and sire. In 1859, he won both of his races including The Derby, in which he landed a huge gamble for his owner despite concerted efforts to prevent him winning. Musjid developed leg problems after the Derby and never ran again. He was retired to stud, where he made little impression before his early death in 1865 from a stomach rupture.
Beadsman (1855–1872) was a British Thoroughbred racehorse and sire. In a career that lasted from July 1857 to June 1858, he ran seven times and won five races. He was unbeaten as a three-year-old and recorded his most important success in the 1858 Epsom Derby. He was retired to stud at the end of the season and became a successful stallion, siring the winners of several important races.
The Merry Monarch was a British Thoroughbred racehorse and sire. In a career that lasted from July 1844 to May 1846 he ran four times and won only one race. That race, however, was the 1845 Epsom Derby, in which he recorded an unexpected victory in a chaotic race. After one race in 1846 he was retired to stud where he made no impression as a sire.
Blink Bonny (1854–1862) was a British Thoroughbred racehorse and broodmare. In a career that lasted from 1856 to 1858, she ran twenty times and won fourteen races. She was the leading British two-year-old of 1856, when she won eight races including the Gimcrack Stakes at York. In 1857 Blink Bonny won five of her seven races and became the second filly, after Eleanor, to defeat the colts in The Derby. In the same season, racing against her own sex, she won The Oaks, the Lancashire Oaks, and the Park Hill Stakes.
Ellington was a British Thoroughbred racehorse and sire. In a career that lasted from 1855 to 1856 he ran eleven times and won four races. A leading two-year-old in 1855, when his wins included the Champagne Stakes at Doncaster, he won only one of his seven races the following year. That win, however, came in The Derby, where his ability to handle soft ground proved to be decisive. Ellington was retired to stud at the end of his three-year-old season, but had very little impact as a sire.
Wild Dayrell (1852–1870) was a British Thoroughbred racehorse and sire. In a career that lasted from October 1854 to September 1855 he ran four times and won three races including The Derby. He was an unusual Derby winner, as neither his owner nor his trainer had any previous experience of Thoroughbred racing. Wild Dayrell was retired to stud at the end of his three-year-old season, and had some success as a stallion, siring several good winners.
Andover was a British Thoroughbred racehorse and sire. In a career that lasted from July 1853 to September 1854 he ran ten times and won eight races. After being beaten in his first racecourse appearance he won his next seven races including the 1854 Epsom Derby. Andover was retired to stud at the end of his three-year-old season. After less than two years as a stallion in England he was sold and exported to Russia.
Daniel O'Rourke was a British Thoroughbred racehorse and sire. In a career that lasted from September 1851 to July 1853 he ran eleven times and won two races. In the summer of 1852, he proved himself one of the best British colts of his generation, winning the Derby at Epsom and the St James's Palace Stakes. Daniel O'Rourke came into the Derby as a maiden and won as an unconsidered outsider on heavy ground. He was one of the smallest Thoroughbreds to win a notable race, being technically a pony under some definitions of the term.
Surplice (1845–1871) was a British Thoroughbred racehorse and sire. In a career that lasted from July 1847 to October 1849 he ran thirteen times and won nine races. He was the leading colt of his generation in England at both two and three years old, with his wins including The Derby and the St Leger in 1848: he was the first horse for forty-eight years to win both of these Classics. His later career was less successful and he was retired to stud in 1850. Surplice had limited success as a sire of winners and died in 1871.
Cossack also known as "The Cossack", was a British Thoroughbred racehorse and sire. In a career that lasted from July 1846 to June 1849 he ran twenty-two times and won three races. In 1847 he proved himself one of the best British colts of his generation, winning Derby and being narrowly beaten in the St Leger. Although he continued to run well in important staying races for the next five seasons, he failed to win another race and was retired to stud in after running once as an eight-year-old in 1852. No subsequent winner of the Epsom Derby has run beyond the age of five. He was later exported to stand as a stallion in France.
Cotherstone (1840–1864) was a British Thoroughbred racehorse and sire. In a career that lasted from September 1841 to July 1843 he ran eleven times and won eight races. After being beaten on his debut, Cotherstone won his next six races including the 1843 2000 Guineas and Epsom Derby. A narrow defeat in the St. Leger Stakes prevented him from being recognised as the first winner of the English Triple Crown. He was regarded by contemporary experts as one of the best British racehorses of his era. After sustaining a serious injury in his only race in 1844 he was retired to stud where he had moderate success.
Little Wonder (1837–1843) was a British Thoroughbred racehorse. In a career that lasted from September 1839 to September 1842 he ran eight times and won only one race. That race, however, was the 1840 Epsom Derby which he won as a 50/1 outsider. Little Wonder was one of the smallest Thoroughbreds to win a major race, standing less than 15 hands high. During his career, there were rumours that he was a "ringer", foaled in 1836 but the allegations were never substantiated. He was briefly retired after being injured in a race in 1842 and died of colic in 1843 while still in training.
Bloomsbury was a British Thoroughbred racehorse and sire. In a career that lasted from May 1839 to July 1841 he ran ten times and won four races. His most important win came on his first racecourse appearance when he won the 1839 Derby. He went on to win important races at Ascot and Liverpool before his retirement after his five-year-old season. He was later exported to stand as a stallion in Germany. Bloomsbury's controversial origins were the subject of two formal objections and a court case which led to a crisis in English racing.
Plenipotentiary (1831–1854) was a British Thoroughbred racehorse and sire. In a career that lasted from April 1834 to April 1835 he ran seven times and won six races. His most important win came in May 1834 when he won The Derby. His only defeat, in the St Leger at Doncaster later that year, was widely believed to be the result of foul play. After three successes as a four-year-old in 1835 he was retired to stud where his record was disappointing. Plenipotentiary was regarded by racing experts as one of the best British racehorses of his era.
Dangerous was a British Thoroughbred racehorse and sire. In a career that lasted from June 1829 to July 1830 he ran six times and won three races, although two of his wins were walkovers. By far his most important win came on his first appearance as a three-year-old when he won the Derby as a 30/1 outsider. Dangerous was retired to stud at the end of his three-year-old season and was shortly afterwards exported to France.
Mameluke was a British Thoroughbred racehorse and sire. In a career that lasted from April 1827 to October 1829 he ran thirteen times and won seven races. Unraced as a two-year-old, he proved himself to be one of the best colts of his generation in 1827 when he won The Derby and finished second in the St Leger. Both races were surrounded by allegations of race-fixing and corruption. Mameluke raced with some success at four and five before retiring to stud. He was not a great success as a stallion.
Emilius (1820–1847) was a British Thoroughbred racehorse and sire. In a career that lasted from April 1823 to October 1824 he ran ten times and won seven races, including a walkover. As a three-year-old in 1823 he was undefeated in six starts, including the Derby. After a less impressive year in 1824 he was retired to stud and became a highly successful and important breeding stallion.
Voltaire was a British Thoroughbred racehorse. He won five of his six races, including the Doncaster Gold Cup in 1828. After retiring from racing he became a successful stallion, siring St. Leger winner Charles the Twelfth and Voltigeur, who won both The Derby and the St. Leger. He was bred and owned by Robert Stephenson, before being sold to William Vane, Marquess of Cleveland, whom he raced for as a three-year-old.
Turkhan was a British Thoroughbred racehorse and sire, who raced during World War II and was best known for winning the classic St Leger in 1940. He showed good form as a two-year-old, winning the Coventry Stakes at Royal Ascot. In the following year he finished second in the rescheduled New Derby and won the Irish Derby before taking a substitute Yorkshire St Leger at Thirsk Racecourse in November. He was then retired to stud where he made little impact as a breeding stallion.
Keystone was a British Thoroughbred racehorse and broodmare. Having suffered from ill-health as a juvenile she recorded an emphatic win in the Epsom Oaks on her second racecourse appearance. She went on to win the Coronation Stakes and three other races as well as finishing second in the Jockey Club Stakes and a possibly unlucky fourth in the St Leger. She failed to win in the following year and was retired from racing. As a broodmare she produced the St Leger winner Keysoe and was the female-line ancestor of Display and Ballymoss.
