Another notable match was London v Sheffield, in which a representative team from the FA played Sheffield FC under Association rules in March 1866; Charles Alcock described this game as "first of any importance under the auspices of the Football Association". Alcock (of Harrow School) of the Wanderers was elected to the committee of the FA in 1866, becoming its first full-time secretary and treasurer in 1870. He masterminded the creation of the Football Association Cup—the longest-running association football competition in the world—in 1871. Fifteen participating clubs subscribed to purchase a trophy. The first Cup Final was held at The Oval on 16 March 1872, fought between the Wanderers and the Royal Engineers (RE), watched by 2,000 spectators.
