Capture of Sponvika Redoubt

The Capture of Sponvika Redoubt (Swedish: Erövringen av Spånviks skansen; Norwegian: Erobringen av Sponvika skanse) took place in late May 1716 during the Swedish invasion of Norway. A 900-strong Swedish detachment from the Västgöta-Dal Regiment, led by Colonel Liebert Rosenstjerna, moved against the redoubt at Sponvika, defended by a 154-strong Norwegian garrison, which capitulated after the arrival of King Charles XII.

By controlling Sponvika, the Norwegians controlled a strongpoint that they used to impede bridge construction around Svinesund and launch minor raids. A previous Swedish assault on the redoubt had been repelled by Dano-Norwegian vessels a few weeks earlier. With orders from Charles XII, Colonel Rosenstjerna, commanding a 900-strong force, positioned his troops around the redoubt on 23 May. Three days later, Charles XII and General Delwig arrived with reinforcements. They initiated a mortar bombardment, expending over 96–160 rounds, which destroyed all three gates of the redoubt. Under the threat of no quarter, the Norwegians capitulated, surrendering four 12-pounders, four 6-pounders, two 3-pounders, and 153 men. Several of the officers taken prisoner were released later that year.
