Scapa Flow: The defences of Britain’s great fleet anchorage 1914-45: No. 85 (Fortress)

.. .a well written, interesting book on a subject of importance that has been largely ignored. The defenses are presented as a unified whole, protecting against surface, submerged and aerial attack... This book is recommended to those with a wide range of interests, from coastal dfense to naval history, to the world wars in general. --Bolling Smith, Coast Defense Journal (March 2010)

There are not too many places you can find any detail, or even a decent plan of Scapa Flow. This book fills a gap. Although this fortified site lacks an impressive battle history, largely due to the success of its defenses, this work will answer many questions for those who want to know what was there... The reader will find there is sufficient detail on the type and location of coastal artillery, air defenses, and the various types of naval defenses that protected the anchorage. Also, the covers the troop units assigned to the islands. There are two good maps showing the defenses in each World War and a number of illustrations of the various types of positions. This book will be of most interest to those that want a source of reference for Scapa Flow or just more information on the defenses of Great Britain. --JE Kaufmann, SiteO, siteo.net (January 2010)
