"the famous Count Rastopchin"
Count Fyodor Vasilyevich Rostopchin
(1763-1826) was the governor of Moscow at this time. A favourite of Tsar Paul I, Rostopchin served as an adjutant general and as Foreign Minister during his reign; he was made governor of Moscow under Alexander in 1810. He was widely thought to be responsible for the fire of Moscow, a charge he first denied, then later seemed to accept, although whether he was actually responsible is doubtful, as Tolstoy goes on to suggest.
