A commemorative service has been held on the Orkney Islands to pay tribute to the 188 crew of two Royal Navy warships that were lost a century ago, when they smashed against rocks in bad weather.
Just one sailor survived when HMS Opal and HMS Narborough ran aground off South Ronaldsay during a patrol on January 12, 1918.
Residents of the Orkney Islands and representatives of the Royal Navy have paid their respects with a wreath-laying ceremony at the destroyers’ monument in Windwick Bay.
The islands served as the principal front-line base for the Royal Navy in both the First and Second World Wars.
The vast natural harbour at Scapa Flow provided an ideal anchorage for the Royal Navy's capital ships.
It's importance meant the Germans tried to disrupt operations there by laying mines, one of which succeeded in sinking HMS Hampshire on June 5,1916, killing the British Commander-in-Chief Lord Kitchener, and at least 600 crew.
It therefore fell to smaller ships like HMS Opal and HMS Narborough to patrol the waters and hunt down minelayers or submarines.
But stormy weather on January 12, 1918 called for the destroyers to be ordered back to base for fear of being swamped.
But tragically, due to near-zero visibility, they ran onto the rocks.
Some of the Opal’s crew were washed overboard, others were trapped in cabins and compartments unable to escape before the ship broke in two.
Gunner AB William Sissons managed to swim ashore and sheltered from the elements in a crevice.
He was eventually rescued by a trawler after about 36 hours, having kept himself alive on a diet of shellfish and snow.
