Gladiateur
Gladiateur (1862–1876) was a French Thoroughbred racehorse who won the English Triple Crown in 1865. Gladiateur is called a legend by France Galop and "One of the best horses ever to grace the turf in any century" by the National Sporting Library of Middleburg, Virginia. Gladiateur was not very successful as a sire but his performance on the track remains one of the most impressive in Thoroughbred horse racing history.
