Commanders
1909: Lieutenant   Wardell-Yerburgh

1914: 4th Flotilla Portsmouth, HMS Arrogant and Hazard
HMS Bonaventure, Grimsby.

This submarine was the first submarine built for the navy by the Royal Dockyard at Chatham. She had a larger bridge than the earlier boats of the class, apparently this was not too effective in keeping out the elements.

She was the first submarine to carry out a beach reconnaissance in 1917 at Middlekerke, Belgium. Whilst carrying out this reconnaissance she was dived for a period of 36 hours, many of the skeleton crew were suffering badly from the effects of carbon dioxide poisoning on surfacing.
