'12-inch gun on a monster German submarine, ruthless pests that sank our shipping "without trace"', Harwich, 1918

Stereoscopic photograph, World War One, War At Sea (1914-1918), 1918.

This submarine was part of the German U-boat fleet that was ordered to surrender to the British under the terms of the November 1918 Armistice. They sailed across the North Sea and were met by Royal Navy warships commanded by Rear Admiral Sir Reginald Tyrwhitt. The latter escorted them to Harwich. Before entering the port, British sailors boarded and took control of the submarines. Eventually 122 U-boats and their supporting vessels were taken into Harwich. The German crews were later shipped back to their own country.
