definitely ranged Prussia on the side of the Allies. Aftermath Between 1 January, when Murat moved his headquarters west to Elbing, and 3 January, when Marshal MacDonald, Yorck's superior, arrived in Königsberg, Bülow worked feverishly to move his supplies to Graudenz and about 5,000 men to Kreuzberg, where he arrived on 2 January. On 9 January he retreated west across the Vistula, ceding East Prussia to the retreating French and advancing Russians. On 5 January, Yorck had sent his last messenger to Berlin. On 8 January, he arrived at Königsberg with the Russian general Ludwig Adolf von Wittgenstein. Yorck reaffirmed his commitment to the armistice, but refused Wittgenstein's demand that he fight the French. That day, however, the king's messengers arrived to dismiss Yorck from his command and repudiate his armistice. Yorck refused and in a letter to Bülow on 13 January, he questioned if he had "sunk so deep that he fears to break the chains of slavery, the chains that we have meekly carried for five years?" He declared it "the time to regain our freedom and honour" and protested that he was "a true Prussian".
