In early August a Danish - Norwegian expedition was sent north to take the town of Halmstad and then advance along the Swedish west coast to seek contact with General Gyldenløve's forces. This led to the Battle of Fyllebro where Charles XI of Sweden won a decisive victory over the Danish mercenary force led by a Scotsman, General Duncan, effectively preventing the linking of forces. The Swedes then retreated north to gather more troops. Christian V brought his army to Halmstad and besieged the town for a couple of weeks but gave up and returned to winter quarters in Scania.
