Soothsayer was a British Thoroughbred racehorse and sire best known for winning the classicSt Leger Stakes in 1811. Bred and originally trained in Yorkshire he won the St Leger on his third racecourse appearance when still unnamed. He was later sold and trained for the remainder of his racing career at Newmarket where he won a valuable sweepstakes in 1812 and a match race against the Derby winnerPhantom in 1813. He later became a successful breeding stallion, siring two classic winners and being the Leading sire in Great Britain and Ireland in 1819. He was later exported to Russia where he died in 1827.
Until 1913, there was no requirement for British racehorses to have official names, and the horse who later became known as Soothsayer competed in 1811 as Mr. Gascoigne's ch. c. by Sorcerer. Mr Gascoigne's colt was unraced as a two-year-old and did not make his first appearance until 20 August at York Racecourse. He started the 1/2 favourite for the three runner Peregrine Stakes over one and three-quarter miles but finished second to Mr. Garforth's bay colt by Hambletonian. On 23 September at Doncaster Racecourse Mr Gascoigne's colt was one of twenty-four colts and fillies to contest the thirty-sixth running of the St Leger Stakes. Ridden by Ben Smith he was made the 6/1 second choice in the betting behind Mr Astley's colt Magic, the 2/1 favourite, who had finished second to Phantom in the Derby. He won the classic from Amadis de Gaul, with Scamp in third place. Two days later at the same meeting, the still-unnamed colt added a win in the Doncaster Stakes. Before the end of the year, the St Leger winner was sold for 2000 guineas to Lord Foley, and officially named Soothsayer.
1812: four-year-old season
For the 1812 season, Soothsayer raced exclusively at Newmarket Racecourse and began his four-year-old season on 16 April at the Craven meeting. Despite carrying top weight of 130 pounds he started 5/4 favourite for a ten furlong sweepstakes and won the 750 guineas prize by beating the Duke of Rutland's colt Grimalkin by a neck. This proved to be Soothsayer's only win of the season. At the next Newmarket meeting two weeks later he started 2/1 joint favourite for a 1200 guinea sweepstakes but finished unplaced behind Rainbow and Sorcery. After a break of six months, Soothsayer returned for the Newmarket Hoghton meeting in late October, where he had three engagements, but raced only once. He was withdrawn from both the Garden Stakes and a match against the Duke of Rutland's filly Elizabeth before finishing last of the three runners behind Sorcery in a sweepstakes over the Abington Mile course.
1813: five-year-old season
Soothsayer's only race of 1813 came on 19 April, the opening day of the Craven meeting, when he ran a ten furlong match race against the 1811 Epsom Derby winner Phantom, with each classic winner carrying 119 pounds. Phantom was made the 2/5 betting favourite, but Soothsayer, ridden by Bill Clift defeated the Derby winner easily to claim a 500 guinea prize. Soothsayer was entered in the Garden Stakes on 18 October, but did not run, with Foley paying a 50 guinea forfeit.
Stud career
Soothsayer began his stud career at Newmarket in 1814, standing at a fee of 20 guineas, and a guinea for the groom. Soothsayer was an immediate success as a breeding stallion. In his first season, he sired Interpreter who won the 2000 Guineas and Filagree, who became an extremely successful broodmare, producing Cobweb, Charlotte West and Riddlesworth. His next crop of foals included the Derby winner Tiresias whose victories in 1819 enabled Soothsayer to become that year's Champion sire. By this time he was standing at Chippenham, near Newmarket at a fee of 25 guineas. Despite his success, Soothsayer's popularity appeared to wane, and by 1821 he was standing at Lambton Park, County Durham for 10 guineas a mare. Two years later he was sold and exported to Russia, where he died in 1827.
