Siege of Fredriksten

The Siege of Fredriksten was a siege of the Norwegian fortress of Fredriksten in the city of Halden by Charles XII of Sweden. While inspecting his troops' lines, Charles XII was killed by a projectile that shot into the left side of his head and out of the right. The Swedes broke the siege off, and the Norwegians kept the fortress.

Background

King Charles XII of Sweden made several campaigns into the city during the Great Northern War during his campaign to capture Denmark–Norway. At the close of the Great Northern War, the Norwegian Army had been weakened in early 1716 by withdrawal of 5000 of the best troops to Denmark. When rumors reached Christiania that Charles XII was preparing to invade, all remaining troops in Østerdal and Gudbrandsdal were ordered to the border at Halden and Fredrikstad. The Norwegians expected the Swedes to invade at Kongsvinger, Basmo and/or Halden. It was at Basmo where Charles XII struck, crossing the border March 8, 1716. The Norwegian scorched earth policy and guerrilla raid interdiction of supply chains by the residents of Bohuslen deprived Charles of supplies, while the fortresses still held by the Norwegians behind his lines threatened his supply chain and his retreat if seriously weakened in combat. Charles took Christiania (now Oslo), but without heavy siege artillery, was unable to take Akershus.

Fredriksten is a fortress in the city of Halden in Norway.

History

This Fortresses was constructed by Denmark-Norway in the 17th century as a replacement for the border fortress at Bohus, which had been lost when the province of Bohuslän was ceded to Sweden by the terms of the Treaty of Roskilde in 1658. The fortress was named after King Fredrik III of Denmark and Norway, and the town of Halden was also originally named after him, having been known as Fredrikshald between 1665 and 1928.

The Northern War (1655–1661)

At the close of the Northern War Charles X, having negotiated the Treaty of Roskilde in bad faith, invested Copenhagen in August 1658. Under his orders, in September the new Swedish governor of Bohuslän invaded Norway with 1,500 men and attempted to invest Halden. The inhabitants put up a vigorous defense and the Swedish forces retreated back to Bohuslän.

Five months later in February 1659 the Swedes again attacked. Since their first attack, the garrison had been strengthened. Under the leadership of Tønne Huitfeldt the Norwegian forces again repulsed the Swedish forces. Concurrently, Huitfeldt began construction of fortifications. Cretzenstein, later to be renamed Fredriksten, was the citadel of the new fortification system.
