Mark Harris is a military historian specialising in telling the story of the naval aspects of the Great War.
He aims to reveal new insights from previously unpublished material, using both official archives and records of the experiences of the participants.
This talk tells the authoritative story of the Royal Navy's first submarine campaign, using new research.
Mark says "This campaign saw the first torpedo fired in action by a Royal Navy submarine, the first ship to be sunk and the first submarine to be lost in action.
The submariners were true pioneers, taking the first steps in waging war underwater with the latest technology of their age.
Based on my eponymous book, published by Helion 2021, it was written in collaboration with the Friends of the Royal Navy Submarine Museum, to whom proceeds from book sales and talks are donated."
