What is "cadland"

Cadland (1825–1837) was a British Thoroughbred racehorse and sire. In a career that lasted from April 1828 to 1831 he ran twenty-five times and won fifteen races, with several of his wins being walkovers in which all of his opponents were withdrawn. In the summer of 1828 he ran a dead heat with The Colonel in the Derby, before winning the race in a deciding run-off. He went on to have a long and successful racing career, winning a further eleven races before his retirement, and developing a notable rivalry with his contemporary Zinganee. Cadland was disappointing as a sire of winners in England and was exported to France, where he was much more successful. He died in 1837.
