Sweden called off the siege of Fredriksten
Sweden called off the siege of Fredriksten in Norway after the death of their king Charles XII. In the Autumn of 1718 Charles had once more attacked Norway, intending to first capture Halden to be able to sustain a siege of Akershus. By first taking the border areas, Charles wished to avoid a repeat of the fiasco he had suffered two years before. The 1,400 strong garrison of Frederiksten fought ferociously to hold back the invasion, but suffered a severe setback when, on 8 December the forward fortification Fort Gyldenløve fell.

Encouraged by their very hard-fought success the Swedish army intensified their efforts against the main fort. The Swedish trenches had almost reached the main fortification walls when on the evening of 11 December (Swedish calendar: 30 November) 1718, a bullet struck and killed Charles XII while he inspected the work. The death of the king effectively ended the attack on Fredriksten and the invasion was called off on this day in 1718, leading to the conclusion of the war.
