Attributed in N.Y. Times, 26 Dec. 1886. The earliest trace of this quotation was in Charles de Montalembert, De l'Avenir Politique de l'Angleterre (1856).

In fact,Wellington was a notably unenthusiastic alumnus of Eton, and Elizabeth Longford, in Wellington: The Years of the Sword (1969), concludes that "probably he never said or thought anything of the kind."
