I am instinctively wary of formulaic approaches that risk imposing patterns on—and hence, in my judgement, doing violence to—the sources . . . [This does not] mean that I accept uncritically whatever our sources tell us. While no disciple of Postmodernism, I have tried to stand outside the source material and to remember that historians can never hope to retrieve ‘what actually happened’—though that does not, in my view, absolve them of the responsibility of trying to get as close as possible to it.
