Denmark–Norway, who wanted to regain its territories lost in 1658, supported Brandenburg-Prussia and invaded the Swedish possessions in Germany in 1675.

[1] In autumn, the Swedes had already been pushed back to the North German Coast, and the Brandenburgians, under Elector Frederick William, subsequently launched a siege on one of the Swedish Empire's last continental holdings, Wolgast.

[2] However, the Swedish commander, Major Blix, did not want to wait for that and subsequently negotiated with the Brandenburgians.

[2][4] According to Jensen, any German-born Swedish soldiers were forcibly enlisted by Frederick William,[6] while Wimarson asserts that, despite Imperial letters prohibiting Germans to fight for Sweden, the Wolgast-accord allowed for an exception; they could, however, join the Bandenburg-Prussian Army if they so wished.

[5] After this conquest, Frederick William turned his attention to Anklam, which he sought to seize in order to better approach Stettin.
