Francis Stephen of Lorraine was indeed named Emperor FrancisI (despite dissenting votes from Prussia and the Palatinate), achieving one of Maria Theresa's major goals in the war. Meanwhile, supplies had run low in the Prussian camp in Bohemia, and Prussia's forces were gradually pushed back by Austrian probes. On 29 September Prince Charles's army staged a surprise attack on Frederick's camp near the village of Soor; the resulting Battle of Soor ended in a Prussian victory, despite the Austrian surprise and superior numbers. The Prussian's supplies were exhausted, however, and they withdrew again into Upper Silesia for the winter, driving out the Austrian light troops that had entered the region ahead of Prince Charles's main force. Late 1745: Battles of Hennersdorf and Kesselsdorf Prussia and Britain hoped the Austrian defeats at Hohenfreidberg and Soor would persuade Austria to come to terms and concentrate its efforts against France, but Maria Theresa was resolved to fight on. On 29 August Austria and Saxony had agreed on a more offensive alliance aimed at seizing Prussian territory, and in early November they began a new offensive from multiple directions toward Brandenburg. Prince Charles's Austrian army marched north from Bohemia toward Lusatia, while the main Saxon army under Frederick Augustus Rutowsky prepared to attack from western Saxony, hoping together to seize Berlin and end the war outright. On 8 November Frederick was informed of these movements and ordered LeopoldI to prepare his troops in western Brandenburg, while Frederick himself departed for Lower Silesia to gather forces to meet Charles's advance. Prussian forces quietly paralleled Prince Charles's march through Lusatia, until the Austrians had come nearly to the Brandenburg border. There, on 23 November Frederick launched a successful surprise attack on Charles's camp at Katholisch Hennersdorf; this Battle of Hennersdorf ended with the Saxon elements of the allied army destroyed and the larger Austrian force confused and scattered. Charles and his remnants were forced to retreat back into central Saxony and Bohemia, leaving Lusatia under Prussian control. Meanwhile, LeopoldI's army advanced into western Saxony on 29 November against minimal resistance, progressing as far as Leipzig by the next day and occupying that city. From there, his army and Frederick's converged toward Dresden in early December. Frederick's force attempted to come between the Saxon capital and Prince Charles's Austrians, while Leopold's army advanced directly upon Rutowsky's Saxons, who were entrenched beside the village of Kesselsdorf.
