"Flying Officer Arne has completed two tours of operations over the North Atlantic during which time he has always shown the greatest keenness to seek out the enemy no matter how trying or hazardous the task. His precise navigation has always been held in high regard and on one occasion was directly responsible for an attack on an enemy submarine. His great enthusiasm and devotion to duty at all times have been most praiseworthy."
