Until the last days of the war, Dönitz believed that Norway should be kept in order to deploy submarines against Allied vessels, and on 3 May the Kriegsmarine Naval Warfare Command informed U-Boat staff that even if Germany itself were occupied, submarines would still sail from Norway.
Sampai hari-hari terakhir perang, Dönitz percaya bahwa Norwegia harus dipertahankan dalam rangka meluncurkan serangan kapal selam terhadap kapal-kapal Sekutu, dan pada 3 Mei Komando Peperangan Laut Kriegsmarine memberitahu staf U-Boat bahwa bahkan jika Jerman sendiri diduduki, armada kapal selam masih harus berlayar dari Norwegia.
