THE centenary of a submarine which disappeared, and its sister, will be marked at a museum in Gosport.
The Royal Navy Submarine Museum in Haslar Road will play host to a talk about the AE1 and AE2 submarines, built in 1913.
During the First World War both boats served in a task force in September 1914 to remove a German colony at New Guinea.
But the AE1 was lost forever when on patrol on September 14 1914 – her disappearance remains a mystery.
The AE2 went on to join the British fleet at Mudros on April 25 1915 and was the first boat to breach the heavily guarded and mined Dardanelles and enter the Sea of Marmara.
Tom Tribe, the chairman of the AE1 UK Memorial Committee will tell the story of the two boats.
Tickets cost £10 for the talk on Thursday, May 16 at 7pm.
Call (023) 9254 5036 to book and for more information.
