The wreck of the first Royal Navy submarine to fire a torpedo in the First World War has been found on the seabed 100 years after she sank.
The 29 men of the submarine E5 all perished when she went to the bottom in 1916.
The boat was thought to have struck a mine during a rescue operation to aid a stricken trawler near Heligoland Bight off the coast of The Netherlands.
Now, reports The Daily Mail, divers have located her hull after it was agreed to briefly suspend the busy shipping lane beneath which it rests.
They found the hatches open, suggesting that the crew made an unsuccessful attempt to escape.
There was no sign of major damage to the hull, indicating that the E5 was not a victim of enemy action.
HMS E5 fired the first British torpedo of the war in the Battle of Heligoland Bight on August 28, 1914.
