Fate:
On completion and during passage to Portsmouth, whilst off Lands End, the unreliable engines had broken down and she had had to be taken in tow.

In the rough sea she had rolled and the sea had entered the batteries, the submarine was filled with chlorine gas, choking the crew and forcing them to abandon the boat.   They put into Falmouth to effect repairs to the batteries and then proceeded (in tow) to Portsmouth.

Rammed and sunk by SS Berwick Castle 18th March 1904 off Portsmouth, no survivors.
Raised 18th April 1904 and eventually used as target, sunk August 1911.
