On this date in 1812, Daniel Dawson “suffered the awful sentence of the law, at the top of Cambridge Castle, amidst a surrounding assemblage of at least twelve thousand spectators, it being market-day.”
The crowd was an appropriate ornament to the condign punishment of the most famous horse-poisoner in English history — and perhaps the most severely-punished sports cheat in all of modernity.
A tout scrabbling his living about the storied Newmarket tracks of Cambridge, Dawson killed the favorite for a high-profile race (and three other horses besides) by poisoning their trough, intending only to hamper the beasts enough to make good a variety of bookies’ bets against the fair Pirouette.
Although acquitted for that crime, Dawson was promptly returned to the dock for a previous, and previously unsolved, horse-poisoning, and convicted under a “black act” statute to punish livestock-killing.
According to the inevitable trial pamphlet, freely available from Google Books,
DAWSON behaved with a sullen and impudent levity during the trial, and he frequently abused the witnesses whilst giving their testimony, loud enough to be heard throughout the court … with horrid imprecations, ill becoming his unhappy situation, and at other times he was nodding at and saluting with his hand different persons in court. The verdict of GUILTY had not the slightest effect on him, and his general conduct was altogether depraved. On his return to the castle, his conduct, at times, bordered on insanity, and he appears too illiterate to feel a consciousness of wrong, although he has confessed his guilt to the full extent.
(Katherine Watson adds that although Pirouette’s owner sought a reprieve for the poisoner, Dawson “spoke bitterly of the hypocrisy of the Jockey Club, few of the members of which were above cheating.”)
