While Frederick's army manoeuvred in western Saxony and Thuringia, the Austrian army of Prince Charles and Daun pressed eastward into Lower Silesia. In November they reached Breslau, where they were opposed by the Silesian garrison under Bevern. The Austrians had overwhelming numbers, and in the Battle of Breslau on 22 November they drove the Prussians from the field. Bevern himself was taken prisoner, and the bulk of his remaining forces retreated toward Glogau, leaving behind some thousands to garrison the city against a siege; the commander of the garrison surrendered Breslau to the Austrians on 25 November in return for safe passage.
