The National Archives, Kew, HS 9/800/6:
"His military service finished, he returned to his old ship until the Spring of 1939 when he signed on ss "ANFIN JARL" sailing between Oslo and Tromsø. This lasted for four months and in the summer of 1939 he again served aboard "DROTTNING MAUD" until February 1940 when he started his second period of military training. He then returned to "DROTTNING MAUD" and was on board when war broke out.
The ship was between Trondheim and Bodø when war broke out and when she arrived in Bodø JOHANSEN volunteered for service but was told to remain with his ship which would be required for troops. On 1st May the ship was bombed by a German plane and sank i Folvik Gratangen. JOHANSEN was taken by the English Destroyer [...] to Harstad where he volunteered again but there was nothing for him to do. It was impossible for him to go home to Trondheim as that town was occupied. He therefore obtained work at a garage and worked there until the capitulation. [...]
In the autumn of  he signed on ss "KONG HARALD" sailing between Trondheim and Kirkenes but left to go aboard ss "TRONDHEIM" in December 1940 as his father was working on board and the 1st Mate, VON, was a friend of his. He sailed between Oslo and Kirkenes until he discovered she was to sail to Germany in June 1941 and therefore he left and went to Tynset to live with his sister Mrs. By for two months.
After this he got work on board m.v. "KONG HARALD" sailing between Tromsø and Trondheim and was on board when she was intercepted by the British destroyer off REINE on 27th December 1941. JOHANSEN then asked if he might come to England and permission was granted."
