[1] Bred by Lord Stawell, and one of the many notable offspring of the great Waxy (1790–1818), Blucher's first year of racing was triumphant.

[3] Through his dam, Blucher was twice descended from the noble Herod, the foundation sire through whom the direct male line of the Byerley Turk survives.

[3] Waxy had won the Derby in 1793 and had continued racing until he was injured as a seven-year-old in 1797, when he retired, going to stud the next year and becoming an influential sire.

[6] Blucher first ran at the Newmarket Houghton meeting of 1813, winning a fifteen-guineas Sweepstakes handicap for two-year-old colts and fillies.

[2] He next ran at the Newmarket Craven meeting of 1814, easily winning a two-hundred guineas Produce Stakes for three-year-old colts and fillies.

Other runners included Bourbon, Grand Duchess, Jeweller, Kutusoff, Monkey, Osman, Robin Adair, Sir Tooley Whagg O'Shaughnashane, Wanderer, Wilmington, and an Eagle colt.

In the Port Stakes handicap race for all comers, one hundred guineas each, with seven runners, Blucher started as favourite at six to four and five to four on, but was beaten into second place by his half-sister Wire, a three-year-old filly by Waxy out of Penelope.

[9] Following his retirement, Blucher stood as a stallion at Marelands near Farnham, Surrey, priced at ten and a half guineas for a nomination.
