The loss of Blücher and the damage done to Lützow caused the German force to withdraw. The ground troops were landed on the eastern side of the fjord; they proceeded inland and captured the Oscarborg Fortress by 09:00 on 10 April. They then moved on to attack the capital. Airborne troops captured the Fornebu Airport and completed the encirclement of the city, and by 14:00 on 10 April it was in German hands. The delay caused by the temporary withdrawal of Blüchers task force, however, allowed the Norwegian government and royal family to escape the city.
