In 1918 as WWI was drawing to a close and the Germans knew they had lost, an agreement was made whereby the Germans were instructed to bring their entire High Seas Fleet to the British Grand Fleet’s home harbor at Scapa Flow in the Orkney Islands. The German ships, 74 in total, were manned by skeleton crews at anchor while the details of the armistice were drawn up. Right before the agreement was reached and fearing that their ships would be divided up among Britain, France, Italy and the U.S., the Germans scuttled all the ships one night when a prearranged signal was given.

And, I seem to remember, several of those German sailors while in the act of scuttling their ships, were shot by the British.
