On Midsummer Day 1919 one of the most extraordinary episodes in the history of the sea took place in Scapa Flow, the famous anchorage in the Orkney Islands. Seventy-four ships of the German High Seas Fleet, at that time the world's second greatest navy, scuttled themselves in a calculated act of defiance.
Tonight's film sees this unique event through the eyes of three people who watched it happen, and one man who actively helped it to happen:
Mrs Rosetta Groundwater, William Waterson, Captain R. C. V. Ross, Vizeadmiral Friedrich Ruge
