The HMS E18 was on patrol in the Baltic Sea in May 1916 - one of a handful of British submarines supporting the Russian navy in disrupting German shipments of iron ore from Sweden. It left the port of Reval - now Tallinn, the capital of Estonia - and three days later is reported to have hit a mine. All 33 people on board died.
The wreck was found by Swedish marine survey company MMT near the Estonian island of Hiiumaa. They took pictures of the wreck using a remote-operated vehicle. The photos appear to show the submarine's hatch open, suggesting it hit the mine while on the surface.
