Leo Tolstoy said this quote

But all these hints at foreseeing what actually did happen on the French as well as on the Russian side are only conspicuous now because the event has justified them. If the event had not come to pass, these hints would have been forgotten, as thousands and millions of suggestions and supposition are now forgotten that were current at the period, but have been shown by time to be unfounded and so have been consigned to oblivion.
