“I used to say of him that his presence on the field made the difference of forty thousand men.”
Arthur Wellesley, 1st Duke of Wellington (1769–1852) British soldier and statesman
On Napoleon Bonaparte, in notes for 2 November 1831; later, in the notes for 18 September 1836, he is quoted as saying:
It is very true that I have said that I considered Napoleon's presence in the field equal to forty thousand men in the balance. This is a very loose way of talking; but the idea is a very different one from that of his presence at a battle being equal to a reinforcement of forty thousand men.
