This book tells the story of operations along the northern front, operations that had to contend with fierce weather as well as a determined and capable enemy. While the clandestine, daring operations of the Shetland Bus to maintain contact with occupied Norway are well known, some other aspects of the story have almost faded from memory: the Northern Patrol of armed merchant cruisers based in Shetland in between 1914 and 1918 that implemented an effective blockade on German commerce; the lonely patrols of the Coastal Command flying boats; the military occupation of the Faroes and Iceland in between 1940 and 1945. The book also recounts some remarkable incidents, such as the arrest in 1914 of the staff of the Lerwick Post Office, the laying and clearing of the North Sea mine barrage and the VE Day riots in Reykjavik. Illustrated with over a hundred archive photographs, this is a fascinating glimpse into a theater of war overlooked by other naval history books.
