Tolstoy takes some liberty with Balashov’s conversation with Napoleon. It’s not clear why Balashov hesitates to give the Emperor’s full ultimatum. In any case, Napoleon acts insulted by the fact that he’s invested so much in the advance across the Niemen, only to be met with, in his view, a weakened Russian response. In turn, Napoleon openly insults the Emperor and plays up his own greatness. Tolstoy brings out small humanizing details, like the way Napoleon’s leg trembled when he was worked up.
