 Although Eriksen was honoured for his efforts after the war, he also came under criticism by governmental investigators who felt he had surrendered his fortress sooner than had been necessary.Eriksen defended himself and stated that he had been acting under enormous pressure and that he had in fact opened fire against the German invaders contrary to standing Norwegian military orders to first fire warning shots at intruders.In the investigations by both the Investigative Commission of 1945 and the Military Investigative Commission of 1946 Eriksen was confirmed to have carried out his duties to the full during the German invasion.
