HMS Audacious when new.
HMS Audacious was a King George V class battleship, built for the Royal Navy at Cammell Laird from 1911 to 1913. One year and six days after her commissioning, Audacious put to sea from her base at Lough Swilly for target practice, along with six other new super-dreadnoughts. While making a turn northeast of Tory Island at 8:45 AM, the vessel stuck a mine abreast the port engine room.
The dull thud was not at first thought to be an explosion, so no order to close the watertight doors was given until the ship had completed her turn and failed to right herself. The port and centerline engine rooms flooded, and the ship took on a marked list to port. To counteract the list, compartments were counterflooded on the starboard side, which reduced the list to 10-15 degrees. However, many of these compartments, thought to be watertight, were not.
Progressive flooding from both the damage and the counterflooding proved to be more than the pumps could handle, and the vessel began to settle. She attempted to make port at her best speed of 9 knots, but about 1 hour and 15 minutes after the explosion the rising water in the starboard engine room caused the loss of all power. The vessel went dead in the water, without power to her auxiliary machinery. The British liner Olympic, sistership to the ill-fated Titanic, answered the distress call, and along with the cruiser Liverpool and some destroyers took off all but 250 essential crew members. The giant liner then attempted to tow the wounded battleship to port, but the sea and wind were pulling hard to the south, so the pull line parted. The cruiser, and later the collier Thornhill, also attempted the tow, but the rough weather made salvage impossible. By 5 PM all but 50 crewmen had been evacuated, and they followed an hour later. By 9 PM the list had increased to 30 degrees, and the vessel was down dramatically by the stern. At 10:45 PM she capsized, and 15 minutes later a large explosion of a forward magazine, followed by two smaller secondary explosions, accompanied the sinking of the vessel.
lives were lost in the incident, but one
of Britain's newest and most powerful dreadnoughts
had been lost due to poor damage control.
