This is the fourth of a series of four blog posts about the mysterious disappearance of three lighthouse keepers on Flannan Isle on December 15th 1900. If you feel that you need to read a previous blog post again, just search for “Flannan”.
We have now looked really quite thoroughly at what was, along with the sea serpent, one of the great mysteries of the latter half of the nineteenth century. Given that there are so many plausible theories, but no forensic leads, such as bodies to examine for injuries or marks on the skin, for mercury levels and so on, no absolutely 100% true correct answer will ever be possible. It’s just a case of finding a solution which explains all of the anomalies found by Joseph Moore as he explored the lighthouse and the rest of the island on December 26th 1900.
Having said that, I am the one writing this blog post and I may be the one to decide what the 100% true correct answer might be.
So….here’s the absolute 100% true correct answer…….
A researcher called James Love found out that Thomas Marshall had already been fined five shillings (0.25p) on another lighthouse, when his equipment was left out and washed away during a fierce storm. In modern money, £1 Victorian was reckoned to be between £116-£132. The fine of five shillings, therefore, was approximately £29-£33, and would probably have been increased for a second offence.
Marshall remembered, or was reminded, just before lunch on December 15th, that he had left equipment out yet again, and he put his sea-boots on to go down and put it away. James Ducat offered to come with him to help, and he put his own sea-boots on. The third man, Donald McArthur, had to remain behind because at least one person always had to be in the lighthouse. When they got back, he would start to prepare lunch.
There may have been a storm going on, but in my scenario, there didn’t need to be. The sun set that day at around 4.00pm, so time was easily on their side. Both of them were experienced men and they would have known immediately whether going down to the level of the landing stage was feasible or not. The two men took a very long time, though, and so Donald MacArthur, leaving his sea-boots behind, went out of the lighthouse in his shirt sleeves to see what was going on. At this point, he was not particularly panicking, which explains that the lighthouse gates and door were both closed.
And then suddenly, a gigantic wave hit the landing stage, surged up the cliff, and carried away the box where equipment was always stored, 110 feet above sea level. It immediately drowned Marshall and Ducat, busy far below on the landing stage, and also claimed Donald McArthur, who was just beginning to walk down the path to see where his colleagues were.
The wave may have been part of an approaching storm, or it could have been one of the “Freak waves” which have been discovered in recent years….
You can read the full account in Wikipedia but it begins with:
“Rogue waves (also known as freak waves, monster waves, episodic waves, killer waves, extreme waves, and abnormal waves) are unusually large, unpredictable and suddenly appearing surface waves that can be extremely dangerous to ships, even to large ones………. In oceanography, rogue waves are more precisely defined as waves whose height is more than twice the significant wave height, which is itself defined as the mean of the largest third of waves in a wave record.”
In 1985, the Fastnet Lighthouse off south western Ireland was hit by a wave of 157 feet (48 metres)
One wave was recorded in January 1995 in the North Sea about 100 miles southwest of the southern tip of Norway. It reached a maximum height of 84 feet (25.6 metres).
In 2000 the oceanographic vessel, RRS Discovery, recorded a 95 feet (29 metres) wave off the coast of Scotland near Rockall.
In 2013, a wave of 62 feet (19 metres) was recorded by a buoy between Iceland and Great Britain, off the Outer Hebrides. This cannot have been particularly far from the Flannan Isles. The wave was caused by 50 mph winds. So what does a 100 mph wind create?
I can’t give a reference but I’m sure that years ago I once read an account of a Scottish lighthouse which stood 200 feet above the sea having the turf rolled back by the waves:
I certainly read an account of stones from the sea bottom being lifted by waves and crashing against the windows of a lighthouse some 400 feet above normal sea level:
Such waves are certainly within the realms of possibility. Scientists have identified two regions where huge rogue waves may occur….the northern Pacific south west of Alaska and the North Atlantic to the north west of the Outer Hebrides. Of the two, the waves in the Atlantic tend to be bigger.
Anyway, for what it’s worth, that’s my solution to the Flannan Isle mystery. Now, I must see if there’s any sign of the postman…..
There is a fairly recent film about the Flannan Isle disappearances. It is called “The Vanishing” and makes use of the events at the lighthouse to tell a tale of greed, violence and murder.
Here are the three lighthouse keepers. They look as if they are up to no good:
Overall, once you put to one side for the duration of the film, any serious explanations you may have of the mystery, this is an excellent thriller, well worth the cost of buying the blu-ray. But, let me say again, it is not a documentary, and makes no attempt to offer a serious, scientific, explanation of the keepers’ disappearance. The film has been made to entertain, and it certainly does that!!
