The Siege of Fredriksten, 1718

A plan of the fortress Fredriksten under siege by the Swedish king Charles XII in 1718. 40,000 Swedes laid siege to the fortress of Fredriksten, overlooking the border town of Fredrikshald on the border between Norway and Sweden. The Swedish trenches had almost reached the main fortification walls when on the evening of December 11, 1718, a bullet struck and killed Charles XII while he inspected the work. The death of the king effectively ended Sweden's invasion plans.
