Divers survey Scottish graveyard of first world war submarine disaster

From The Guardian: Divers survey Scottish graveyard of first world war submarine disaster
An underwater war grave containing the victims of one of the worst British naval disasters of the first world war has been surveyed for the first time so it can be preserved in the middle of a windfarm.

The two K Class submarines were destroyed on 31 January 1918 during the so-called battle of the Isle of May, in which 270 lives were lost. The two submarines were sunk and three more damaged along with a surface cruiser.

But no enemy ships were involved in the sinkings, 20 miles off Fife Ness on Scotland's east coast. The deaths were all caused by a series of night-time collisions within the British fleet.

So embarrassing was the incident that even though one officer was court-martialed, the facts were not generally admitted for more than 60 years, until after the death of the last survivor.

Jim Rae, secretary of the Scottish branch of the Submariners Association, said: "It was an absolute bloody disaster from the beginning. The K Class submarines did not have a very impressive record. You can see why those who served in them were known as the suicide club."

The submarines proved far more lethal to their crews than to the enemy, so much so that the K was said to stand for Kalamity. Driven by oil-fired steam turbine engines, they were large and cumbersome, too slow to keep up with surface ships, hard to manoeuvre and stifling for their crews. Of the 18 that were built, none were lost in action but six were sunk in accidental collisions.

In January 1918, as British warships steamed north from Rosyth to join their fleet at Scapa Flow in the Orkneys, they were accompanied by two flotillas of the submarines. The first two subs found themselves bearing down on two minesweepers and changed course. The third, K14, veered to starboard to avoid colliding with them but performed a complete circle as its rudder jammed.

That brought it back into line just in time to be rammed by the last submarine in the group, K22. A battlecruiser, HMS Inflexible, then ploughed into K22.

The first ships in the convoy turned back to rescue the submarines and steamed straight into the chaos. A cruiser, HMS Fearless, rammed K17, another of the subs, sinking it within eight minutes. Then two further submarines, K4 and K6, collided. To complete the disaster, a destroyer then carved through the survivors of K17, killing many of those who had been left in the water. The entire 59-man crew of K4 was lost and all but eight of K17's.

The Royal Navy hushed up the catastrophe and it was not until 2002 that a commemorative plaque was erected on a cairn in Anstruther, the nearest village on the coast, though even that does not refer to the cause of the loss of life. The Submariners' Association does, however, now hold an annual commemorative service.

The site of the two sunken submarines, 100 metres apart and about 50 metres down, has long been known, but the wrecks have now been surveyed by divers from the specialist marine consultants EMU. The area is the proposed site for an offshore windfarm, known as the Neart na Gaoithe project, developed by a company called Mainstream Renewable Power.

The project aims to generate 450MW of renewable energy and may eventually provide enough to power 325,000 Scottish homes. The developers claim it will offset more than 400,000 tonnes of CO2 emissions each year, and contribute towards the Scottish government's target of generating the equivalent of all the country's energy demands from renewable resources by 2020.
