[3] The death of an owner had traditionally canceled all of a horse's entries, but a rule change in 1929 meant that Cameronian's status was not affected, allowing him to take part in the Classics.

[4] Cameronian's sire, Pharos was a top class racehorse who won the Champion Stakes and went on to become a highly successful stallion.

[9] In the 2000 Guineas three weeks later he started at 100/8 and was ridden by Joe Childs,[10] as the stable jockey Fred Fox rode the more fancied Lemnarchus.

Ridden by Fox[13] he broke quickly and was then steadied to track the leaders in the early stages before moving into the lead as the field entered the straight.

At the victory celebration, Dewar, who described himself as "the most delighted man in the world", decorated the Savoy Hotel with a hundred miles of tartan ribbon.

[16] The colt was then rested until the September, when he started odds-on favourite for the St Leger at Doncaster Racecourse, despite doubts from some experts about his ability to stay the one and three quarter mile distance.

[23] Cameronian made a promising start to his stud career by siring the St Leger winner Scottish Union in his first crop of foals.
