Scapa Flow, a vast, natural harbour in the Orkney Islands, served as the Royal Navy’s main base during the two world wars, from where ships sailed to the Battle of Jutland in the First and in convoy to northern Russia in the Second. Thousands of men and women saw service in and around this remote anchorage, including soldiers and sailors who crewed the ships and manned the lonely batteries, and Wrens, nurses and civilians who were posted there.Scapa Flow brings together their memories – the bleak isolation, its implacable winds and glorious sunsets, the camaraderie and good humour – forming a compelling portrait of a unique war station that left its mark on all who served there.
