Battle of Waterloo not won on the playing-fields of Eton

Further illusions shattered by this small book The Encyclopaedia of Fads and Fallacies by Thomas Jay (Elliott Rightway Books, Kingswood Surrey 1958.) Apparently bulls are colour blind so red rags do not bother them, Turkish baths are not Turkish (and they are not baths) and alcohol cannot be drunk in any concentration strong enough to kill germs. Even the assertion that 'The Battle of Waterloo was won on the playing-fields of Eton' also appears to be unfounded according to the iconoclastic T. Jay. It seems a pity, as it is one of those poetic ideas like AE's 'In the lost boyhood of Judas / Christ was betrayed.' What Jay actually says is:

The Duke of Wellington is credited with having said 'the The Battle of Waterloo was won on the playing-fields of Eton.' There is no truth in that assertion. There were only a very small number of officers from Eton at the battle.

The quotation may have been taken too literally by Jay -online research reveals this at the Wikipedia entry on Eton:

According to Nevill (citing the historian Sir Edward Creasy), what Wellington (actually) said, while passing an Eton cricket match many decades later, was, 'There grows the stuff that won Waterloo', a remark Nevill construes as a reference to 'the manly character induced by games and sport' amongst English youth generally, not a comment about Eton specifically. In 1889, Sir William Fraser conflated this uncorroborated remark with the one attributed to him by Count Charles de Montalembert's C'est ici qu' a été gagné la bataille de Waterloo ('It is here that the Battle of Waterloo was won.')
