As far as the boats losses are concerned, only the destroyer North Star and two motor boats went down.
This raid is the most striking instance of military valour and devotion to duty. We feel as though we must emphasize the glorious conduct of the British sailors and the best way is for us to oppose the straight forwardness of the British sailormen to the sly and underhanded methods of the Germans, who only feel apt to sink, without being seen, defenceless boats, thus bringing death on to harmless people.
