HMS Audacious: An early casualty in The Great War

HMS Audacious – Stuck a mine and sank off Donegal, Ireland – 27th October 1914

HMS Audacious, built in 1912, was a King George V-class battleship and formed part of the Second Battle Squadron of the British Grand Fleet of the Royal Navy. While the vessel never got to actively engage in combat, she briefly served as a wartime anchorage for training and gunnery practice before being stuck by a mine off the northwest coast of Ireland in 1914.

Abandoning ship The Audacious takes on water (1914)

On the 24th October 1914 while on exercises on the north west coast of Ireland she struck a mine laid by the German auxiliary mine layer Berlin. Several compartments including the engine rooms became flooded and the crew quickly abandoned ship and the vessel began to sink.

Despite the serious damage inflicted by the mine and the subsequent sinking of the Audacious, there was loss of life was limited to one unfortunate soul.

Three ships,RMS OlympicHMS Liverpool and HMS Fury were quick on the scene and picked up the crew. They then attempted to tow the Audacious back to Lough Swilly but were repeatedly foiled as the tow lines snapped in the heavy seas and the ship sank close to where it had been struck.


After the loss of the Audacious, the Royal navy tried to keep the whole incident a secret. However, this badly backfired. While all the survivors were ordered to keep the event a secret, consistent with their policy of keeping actual ship numbers a mystery to the Germans, rumours inevitably spread. This invariably resulted in a magnified “legend that a whole squadron of first-class vessels had fallen victim to U-Boats and mines. Certainly not the outcome the navy wanted!


Diver’s Delight The 13 inch guns of the Audacious

The site of the wreck, 18 miles northeast of Tory Island Co Donegal, has become a favourite diving location for expert divers. The ship lies at 66 metres below the surface and requires special training and equipment to withstand the pressures and challenges at these depths. Recently a Dutch diver got into trouble when diving at this site when he developed compression sickness. The man was airlifted to safety and has since fully recovered from the incident.

On a much happier end note however, the waters around Donegal are full of other amazing wrecks including a number of ocean liners and U-boats with dives that suit all levels. Irish wrecks online has a great list worth checking out should you ever be fortunate enough to go diving in Donegal.

And if you’re completely new to diving, the Diving Ireland website is a great first stop to begin your adventure!
