Reading a book called “The Last of The Doughboys”, by Richard Rubin. Excellent book on centenarians interviewed in 2003 and 2004 for their involvement and memories of World War I 1914-1918. Most of focus is American entry and time 1917-1918. One part talks about the Navy. One section talks about the armistice and the German Navy sinking their ships in Scapa Flow, in area of Northern Scotland. Want more info here is a link.
