In 1710, the Swedish army in Poland retreated to Swedish Pomerania, pursued by the coalition. In 1711, siege was laid to Stralsund. Yet the town could not be taken due to the arrival of a Swedish relief army, led by general Magnus Stenbock, which secured the Pomeranian pocket before turning west to defeat an allied army in the Battle of Gadebusch. Pursued by coalition forces, Stenbock and his army was trapped and surrendered during the Siege of Tönning.
