Although the Bohemian and Silesian Armies halted at the Rhine, the Army of North Germany continued the campaign. Following the battle of Leipzig, the crown prince of Sweden directed his army to Göttingen. News that Marshal Davout had withdrew to Hamburg allayed Allied fears that he would seek to raise the sieges of Magdeburg and Torgau and then unite with Marshal St. Cyr to create a formidable French army between the Elbe's fortresses. Davout's retreat allowed the individual corps of the Army of North Germany to separate between 1 and 4 November. Bülow's Prussian III Corps moved toward Westphalia, and Wintzingerode's Russian corps continued toward the Weser River. Bernadotte maintained direct command over his Swedish corps and united with Wallmoden's corps, which had held the lower Elbe during the German campaign. In addition, Bernadotte retained General Mikhail Semenovich Vorontsov's infantry corps of Wintzingerode's army corps and received command of General Pavel Aleksandrovich Stroganov's Russian infantry corps from Bennigsen's Army of Poland. With this force of approximately 60,000 men, he advanced toward Hanover to confront Davout. Nothing had changed for the crown prince of Sweden except the urgency of his mission. Since the resumption of hostilities in August, the issue between Sweden and Denmark over the fate of Norway was his main concern.
