Gainsborough (1915–1945) was a British bred Thoroughbred racehorse who won the English Triple Crown in 1918 and became a superior sire. Background Gainsborough was a bay horse bred by his owner Lady James Douglas (1854–1941). The colt was named after the town of Gainsborough, Lincolnshire because his owner liked the sound of the name. Gainsborough was sired by Bayardo, who also sired the 1917 Triple Crown winner, Gay Crusader, and was out of Rosedrop, who won the 1910 Epsom Oaks and £9,809. Gainsborough's damsire was St. Frusquin, who won nine races including the 1896 2,000 Guineas and £33,960. Galopin was duplicated in the third and fourth generations of Gainsborough’s pedigree. He was not a big horse but possessed very good conformation and a kind temperament. One commentator described him as a "horse that would stand a campaign on the Western Front with Sir Douglas Haig on his back." Gainsborough was quite mature when he was offered at the yearling sales but did not reach the reserve that was placed on his price. Lady Douglas sent Gainsborough to trainer Alec Taylor, Jr.'s training centre in Manton, Wiltshire, to prepare for racing. Racing record 1917: two-year-old season As a two-year-old, Gainsborough made three starts at the Newmarket Racecourse , won the Autumn Stakes by two lengths, and was rated the third best juvenile of his generation. 1918: three-year-old season Gainsborough won the 2,000 Guineas, marking the first time that a horse bred by a woman won one of the British Classic Races and the first time a Classic winner carried a woman's colours. He was ridden by jockey Joe Childs, who, to help the War effort, donated his winnings to his 4th Hussars regiment to which he was attached. Following his win in the 2,000 Guineas, Gainsborough won the most prestigious race in England, The Derby, which was run at Newmarket owing to wartime restrictions. He then won the Gold Cup against older horses at a distance of just over two miles (3,219 metres) and in autumn won the September Stakes—a substitute race for the Doncaster St. Leger Stakes—by three lengths over a field including the Oaks winner My Dear and Prince Chimay to become the 13th U.K. Triple Crown Champion in history. Gainsborough finished second to Prince Chimay in the Jockey Club Stakes, after which he was retired. Stud record In 1920, Gainsborough was retired to Lady Douglas's newly established Harwood
