| 25-06-1921 | K15 was moored alongside the light cruiser HMS Canterbury, in the tidal basin at Portsmouth. Most of the crew were on leave when a watch keeper discovered that the submarine was sinking, with the stern already awash. The watch were quickly roused and scrambled aboard the Canterbury. The submarine slowly submerged amid streams of bubbles. The accident was caused by hydraulic oil expanding in the hot weather and contracting as the temperature dropped causing a loss of hydraulic pressure and causing vents to open. |

By its underwater nature, the submarine service remains one of the more perilous jobs in the Royal Navy. Advanced technology means that today's nuclear-powered vessels can now remain 120 days without surfacing and deliver a cruise missile with pinpoint accuracy to a target 400 miles away. There are also hundreds of checks constantly carried out on board and improved training for modern submariners. But there is always the potential for disaster
The combined forces invasion of the Belgian port of Zeebrugge on 23 April 1918 remains one of Britain's most glorious military undertakings; not quite as epic a failure as the charge of the Light Brigade, or as well publicised as the Dam Busters raid, but with many of the same basic ingredients.
A force drawn from the Royal Navy and Royal Marines set out on ships and submarines to try to block the key strategic port, in a bold attempt to stem the catastrophic losses being inflicted on British shipping by German submarines. It meant attacking a heavily fortified German naval base. The tide, calm weather and the right wind direction for a smoke screen were crucial to the plan.
Judged purely on results, it can only be considered a partial strategic success. Casualties were high and the base only partially blocked. Nonetheless, it came to represent the embodiment of the bulldog spirit, the peculiarly British fighting elan, the belief that anything was possible with enough dash and daring.
The essential story of the Zeebrugge mission has been told before, but never through the direct, first-hand accounts of its survivors, including that of Lieutenant Richard Sandford, VC, the acknowledged hero of the day, and the author's great uncle. The fire and bloodshed of the occasion is the book's centrepiece, but there is also room for the family and private lives of the men who volunteered in their hundreds for what they knew effectively to be a suicide mission.
Zeebrugge gives a very real sense of the existence of the ordinary British men and women of 100 years ago, made extraordinary by their role in what Winston Churchill called the 'most intrepid and heroic single armed adventure of the Great War.'
