Assassin (1779 – c. 1794) was a Thoroughbred racehorse that won the 1782 Epsom Derby. His breeder, Lord Egremont, won the Derby for the first time with Assassin. Assassin raced until he was a five-year-old and was retired to Egremont's stud in Petworth. He was not a successful sire.

Background

Assassin was foaled in 1779, at Lord Egremont's estate Petworth House. Assassin's sire, Sweetbriar, was an undefeated racehorse that earned 5,400 guineas during his racing career for his owner Lord Grosvenor. Sweetbriar stood at Oxcrofts Farm near Balsham.^[1] Assassin's dam, Angelica, was foaled in 1761 and was breed by Mr. Shafto, the owner of her sire Snap. Assassin was Angelica's eighth foal and she produced eleven foals between 1768 and 1782, including Assassin's full-sister Medëa. Angelica was euthanised in 1787.^[2]

Stud career

By 1789, Assassin was still standing at Petworth for a fee of two guineas per mare alongside the more expensive stallions Mercury (10 guineas) and Trentham (3 guineas).^[12] For the 1793 breeding season, he was relocated to Langley Park near Colnbrook and stood for a fee of 3 guineas per mare and a five shilling groom's fee.^[13] His fee at Langley Park was reduced to two guineas for the 1794 season^[14] and he did not appear in the register for 1795.

Assassin was not a successful sire. His most notable offspring were the fillies Cow^[7] and Rag (foaled in 1786 out of Chanticleer's dam).^[15]

Pedigree

• Assassin was distantly inbred 4 × 4 to Bartletts Childers, meaning that this horse appears twice in the fourth generation of his pedigree.
