 Tristan was a dark chestnut horse standing just under 16 hands ( 64 inches , 163 cm ) high , bred by Robert St Clair @-@ <unk> , 4th Earl of <unk> at the Easton <unk> near Great <unk> in Essex . As a <unk> , Tristan was bought by the French owner C. J. Lefevre , who sent the colt to be trained by Tom Jennings at the Phantom House stable at Newmarket , Suffolk . Jennings would later say that Tristan had been <unk> as a <unk> before his arrival at Newmarket and this explained his well @-@ known temperament problems . Tristan was ridden in most of his races by George Fordham and came to show a strong and sometimes violent dislike for other <unk> .
