The first appearance of Gladiateur upon the race-course was at the Newmarket autumn meeting of 1864, where he won the Clearwell Stakes, beating a field of twelve horses. He was kept sufficiently "shady," however, during the winter to enable his owner to make some advantageous bets upon him, though it required careful management to conceal his extraordinary powers. His training remains a legend in the annals of the stables of Royal-Lieu, where the jockeys will tell you how he completely knocked all the other horses out of time, and how two or three of the very best put in relay to wait upon him were not enough to cover the distance. Fille-de-l'Air herself had to be sacrificed, and it was in one of these terrible gallops that she finished her career as a runner. Mandarin alone stood out, but even he, they say, showed such mortal terror of the trial that when he was led out to accompany his redoubtable brother he trembled from head to foot, bathed in sweat. In 1865, Gladiateur gained the two thousand guineas and the Derby at Epsom, and for the first time the blue ribbon was borne away from the English. "When Gladiateur runs," said the English papers at this time, "the other horses hardly seem to move." The next month he ran for the Grand Prix de Paris. His jockey, Harry Grimshaw, had the coquetry to keep him in the rear of the field almost to the end, as if he were taking a gallop for exercise, and when Vertugadin reached the last turn the favorite, some eight lengths behind, seemed to have forgotten that he was in the race at all. The public had made up its mind that it had been cheated, when all at once the great horse, coming up with a rush, passed all his rivals at a bound, to resume at their head his former easy and tranquil pace. There had not been even a contest: Gladiateur had merely put himself on his legs, and all had been said. These three victories brought in to Comte de Lagrange the sum of four hundred and forty-one thousand seven hundred and twenty-five francs, to say nothing of the bets. Gladiateur afterward won the race of six thousand metres (two miles fourteen furlongs) which now bears his name, and also the Great St. Leger at Doncaster. He was beaten but once--in the Cambridgeshire, where he was weighted at a positively absurd figure, and when, moreover, the track was excessively heavy. After his retirement from the turf he was sold in 1871 for breeding purposes in England for two hundred thousand francs, and died in 1876.
