The war was continuing indecisively when on 14 October Marshal Daun's Austrians surprised the main Prussian army at the Battle of Hochkirch in Saxony. Frederick lost much of his artillery but retreated in good order, helped by dense woods. The Austrians had ultimately made little progress in the campaign in Saxony despite Hochkirch and had failed to achieve a decisive breakthrough. After a thwarted attempt to take Dresden, Daun's troops were forced to withdraw to Austrian territory for the winter, so that Saxony remained under Prussian occupation. At the same time, the Russians failed in an attempt to take Kolberg in Pomerania (now Kołobrzeg, Poland) from the Prussians.
