The National Archives, Kew, HS 9/781/4 (Report dated November 1945):
"Dkm. K. IVERSEN has been associated with the SHETLAND Base throughout four winter seasons having joined the Unit on 16th September 1941. He served until 1943 as an engineer on one of the fishing boats used on clandestine operations and subsequently as Second Engineer on S.C. HESSA.
He sailed in all on forty-eight operations both by fishing boat and subchaser and it is to his credit that in spite of the misfortunes and heavy losses which attended the operations of the winter of 1942/43 he showed undiminished keenness to continue in this service. When subsequently the Base was re-requipped with U.S. suchasers he quickly adapted himself to the new conditions of service and continued as a most valued member of the Unit. These operations were confined to the winter months, and the ships had to sail through conditions of storm and darkness which were extremely trying to morale. It speaks highly for Dkm. K. IVERSEN's courage and endurance that he was able and willing to face four such winters."
