Firebrand was sired by Wilson's stallion Lamplighter, a successful racehorse who won the Craven Stakes, The Whip and several King's Plates at Newmarket.
[3][4] Firebrand was a lightly built, delicate filly and Bentinck sought to build her strength with an experimental diet consisting of milk, flour and newly laid eggs.
Seven of the original twenty-one entries appeared for the race, with Lord Exeter's filly Celia starting favourite ahead of Eliza, Equation and Passion.
Firebrand, whose odds were not recorded in the Racing Calendar, created an upset, winning by a length from Celia with Eliza in third place.
[8] A month after her win at Newmarket, Firebrand was moved up in distance to challenge for the Oaks Stakes over one and a half miles at Epsom.
[9] Firebrand moved into the lead early in the straight but faded in the closing stages[10] and finished third, beaten two lengths by Our Nell and Meal.
She finished fourth of the five runners behind Colonel Cradock's filly Sally, who defeated the St Leger winner Blue Bonnet by a neck.
