Fate:
Also served in the Mediterranean and Venice.

Sailed from Tenedos on 12th December 1914 in an attempt to break into the Sea of Marmara.

She was the first British submarine to attempt to force her way into the Sea of Marmara.   She not only succeeded in doing so but also sank the battleship Messudieh from a range of some 800 yards.   This was an incredible feat for a submarine which was designed for coastal work.

Holbrook was awarded the first submarine VC of the war, his First Lt, Lt. S. T. Winn the DSO and the remainder of the crew were awarded either the DSC or DSM.

Also made an unsuccessful attempt to sink E15 after she had run aground trying to enter the Sea of Marmara.

She also scored a first when capturing the crew of the Austrian flying-boat L59 which had been forced down whilst experiencing engine trouble during January of 1916.

Converted to Surface Patrol Craft and renamed 'S11' for service on the Otranto Barrage.

Sold 1919 and scrapped in Italy.
