Røros was burned to the ground in 1678 and 1679 by the Swedish Army during the Scanian War. In 1718, during the Great Northern War, the town was once again taken by the Swedish Army, led by General De la Barre, who made up the southern arm of the main Swedish Army under Carl Gustaf Armfeldt. De la Barre took the city and all their mined copper at gunpoint.
