On 16/1/1914 A7 and four other submarines were undertaking dummy torpedo runs against gunboat HMS Pygmy and depot ship HMS Onyx. A7 dived to commence an attack and never resurfaced.

It took six days to locate A7 and three salvage attmpts were made to pull her clear of the mud. Her hull was damaged and further attempts were reluctantly abandoned. Nine crew members remain buried inside in wreck.
