Instead of the demand of four months earlier to withdraw from Pomerania, only a withdrawal beyond the Niemen was now demanded. Napoleon turned quickly and began to pace the room.
“You say the demand now is that I am to withdraw beyond the Niemen before commencing negotiations, but in just the same way two months ago the demand was that I should withdraw beyond the Vistula and the Oder, and yet you are willing to negotiate.”
He went in silence from one corner of the room to the other and again stopped in front of Balashëv. Balashëv noticed that his left leg was quivering faster than before and his face seemed petrified in its stern expression. This quivering of his left leg was a thing Napoleon was conscious of. “The vibration of my left calf is a great sign with me,” he remarked at a later date.
“Such demands as to retreat beyond the Vistula and Oder may be made to a Prince of Baden, but not to me!” Napoleon almost screamed, quite to his own surprise.
