These binoculars should have been lost when the HMS Invincible was sunk at the Battle of Jutland.
It was the largest naval battle and the only full-scale clash of battleships during the First World War. Involving a total of 279 ships on 31 May 1916, the North Sea bore witness to the major clash between the British Grand Fleet and the German High Seas Fleet. Both sides suffered heavy losses in ships and men, but despite being the biggest naval surface engagement to date Jutland was one of the most keenly-felt disappointments of the war, with neither side achieving a decisive victory.
These binoculars were aboard the British warship HMS Invincible when it was sunk, with the loss of 1,026 lives. They were recovered from the wreck by a Norwegian fishing vessel.
