“Of four hundred thousand who crossed the Vistula,” he wrote further of the Russian war, “half were Austrians, Prussians, Saxons, Poles, Bavarians, Württembergers, Mecklenburgers, Spaniards, Italians, and Neapolitans. The Imperial army, strictly speaking, was one third composed of Dutch, Belgians, men from the borders of the Rhine, Piedmontese, Swiss, Genevese, Tuscans, Romans, inhabitants of the Thirty-second Military Division, of Bremen, of Hamburg, and so on: it included scarcely a hundred and forty thousand who spoke French. The Russian expedition actually cost France less than fifty thousand men; the Russian army in its retreat from Vílna to Moscow lost in the various battles four times more men than the French army; the burning of Moscow cost the lives of a hundred thousand Russians who died of cold and want in the woods; finally, in its march from Moscow to the Oder the Russian army also suffered from the severity of the season; so that by the time it reached Vílna it numbered only fifty thousand, and at Kálisch less than eighteen thousand.”
