After a fiercely cold winter struck, no military movements took place until June, when Ulrik Frederik Gyldenløve sent 2,000 men under the command of general Hans Løvenhjelm across the border to Bohuslän to retake Strömstad.

Carlsten no longer had outposts, and after strong bombardment from all sides, finally surrendered on 23 July, with the condition that the commander along with his men would be sent to Värmland.

After taking Carlsten, Gyldenløve installed a strong detachment of troops under Løvenhjelm to defend Marstrand before returning to Norway.

However, Løvenhjelm soon found himself threatened by approaching Swedish forces, and retired with his men to Strömstad in August.
