Wellington's reply when asked, late in his life, what was the most inane remark he had ever heard, as quoted in Journals of Alec Guinness (February 1998) by Alec Guinness

A Battle For Life (July 1958)
Context: This was a good beginning. All the outmoded rules of the hospital were broken. Minds which had been tied down by subservience to foreign experience were now set in motion. People began to speak, to think and to act boldly. A new world opened in front of them. They knew that what they were doing now was something unprecedented which doctors in capitalist countries had not been able to do. They were engaged in a battle to save lives and as the scope of the battle became wider an increasing number of people were drawn in. Later on when a difficulty occurred in the course of treatment they solicited the opinions of many doctors both within and without the hospital, depending on the wisdom of the many to tide over one crisis after another.

As quoted in The New York Times (26 December 1886), and in Words on Wellington (1889) by Sir William Fraser, this is almost certainly apocryphal. The first attributions of such a remark to Wellington were in De l'Avenir politique de l'Angleterre (1856) by Charles de Montalembert, Ch. 10, where it is stated that on returning to Eton in old age he had said: "C'est ici qu'a été gagnée la bataille de Waterloo." This was afterwards quoted in Self-Help (1859) by Samuel Smiles as "It was there that the Battle of Waterloo was won!" Later in Memoirs of Eminent Etonians (2nd Edition, 1876) by Sir Edward Creasy, he is quoted as saying as he passed groups playing cricket on the playing-fields: "There grows the stuff that won Waterloo."
Elizabeth Longford in Wellington — The Years of the Sword (1969) states he "probably never said or thought anything of the kind" and Gerald Wellesley, 7th Duke of Wellington in a letter published in The Times in 1972 is quoted as stating: "During his old age Wellington is recorded to have visited Eton on two occasions only and it is unlikely that he came more often. … Wellington's career at Eton was short and inglorious and, unlike his elder brother, he had no particular affection for the place. … Quite apart from the fact that the authority for attributing the words to Wellington is of the flimsiest description, to anyone who knows his turn of phrase they ring entirely false."
