Event of 1814: Swedish–Norwegian War: Battle of Lier ends in a Norwegian victory.

Background. Major General Carl Pontus Gahn received orders to advance on the Norwegian fortress-city of Kongsvinger. The strategic objective was to draw Norwegian troops from other locations to defend this town. This maneuver aimed to leave other areas temporarily weakened, creating opportunities for Swedish offensives elsewhere in Norway.

Engagement. The battle involved an outnumbered Swedish force attempting to storm the Norwegian entrenchment. The Norwegian victory served as an important part to boost morale among the Norwegian troops. During the fighting, the Norwegian vanguard retreated back to Kongetorp, where they met with a lieutenant. The 1814 fighting involved far larger forces than the 1808 battle at Lier.

Historical Context. This was the second time during the Napoleonic Wars that a battle had taken place at Lier, the first was in 1808. The battle was the first major action of the war. The engagement is documented in Swedish military records, including Anteckningar under Svenska Arméens Fålttåg 1813 och 1814.
