At the same time, after the defeat of imperial Brandenburg in the Battle of Turckheim against the French on 26 December 1674, Brandenburg's main army marched to its winter quarters in and around Schweinfurt, reaching the area on 31 January 1675. Because of wintry weather and the losses he had suffered, the Elector decided that he would not deploy his main army immediately on a new campaign in the Uckermark. In addition, a sudden withdrawal from the western theatre of war would have alarmed Brandenburg-Prussia's allies - thus achieving the ultimate goal of the Swedish invasion, i.e. to force Brandenburg to withdraw from the war with France.
