“I used to say of him that his presence on the field made the difference of forty thousand men.”
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.
