At Tilsit, Rostov’s recent experiences build to an emotional climax. He’s gone from a disease-ridden hospital to an imperial banquet, witnessing the gamut of the war. He struggles to reconcile the agonies and injustices of war on a personal level with the beauty and ceremony of alleged peace on a symbolic level. In the end, he’d rather be around fellow soldiers than banqueting officers, and even then, he can’t make sense of what’s real. His outburst suggests that he’s suppressing his own criticisms of Alexander, sensing that everything will unravel if he dwells on them.
