Campbell writes that the order to flood came from the Captain via the Transmitting Station (the fire control room below decks) and was sent by a Stoker after the order had been double checked. 2/
I spent a long time a decade ago trying to find Campbell’s source for this but never could. Until last year that is. The official report of the officer in charge of the Transmitting Station is preserved in Beatty’s papers, to whom it was sent on 11 June 1916. 3/
It confirms the order to flood came from the bridge, had to be double checked, and the Stoker who was sent with the message actually helped another Stoker flood the magazine. The Stoker was promoted and mentioned in despatches. 4/
Half a century later historian Arthur Marder was informed of this version of events by the officer in charge of the Transmitting Station. Marder’s response? Wait until the officer died then ignored his account for his revised Jutland volume. Historiography is hell. 5/
What Harvey definitely did not do with his legendary dying breaths was order hundreds of pounds of cordite returned to the magazine. When it burnt almost half an hour later it killed dozens of men after a handing room hatch had been left open contrary to orders. 6/
This disregard for regulations may have saved H.M.S. Lion, however, as official reports suggest the venting caused by the open hatch (and the roof already blown off the gunhouse) may have relieved pressure on the magazine doors. Truly a warped sequence of events. 7/

A thread on propellant loading and safety precautions at the Battle of Jutland. This image shows a simplified cross section of a British dreadnought battleship or battle cruiser mounting and is fairly representative of the various calibres. #history 1/
The propellant was called cordite for obvious reasons. Cords were bundled together in a silk bag and called a cartridge. At ONE end was a gunpowder igniter covered by a protective tear off disc. Four cartridges were required for each shell. 2/
Cartridges were stored in brass cases, two to a case (case for 15-inch cartridges shown). These were NOT called Clarkson or Clarkson’s Cases. They were not entirely flashlight on account of the danger of spontaneous ignition, and had lids at both ends. 3/
I’m going to take you on a journey now. How do you make a 15-inch battleship gun? This is quite a long thread and is an amazing insight into British engineering in the early 20th century. The clips speak for themselves. Enjoy and share! #history 1/
A quick, angry #history thread about Room 40 because apparently historians are still making shit up about its location. Last year Barry Gough wrote that it was "in a quiet wing of the Old Admiralty Building". 1/
Those windows outlined in green? That's Room 40. Where the blue lines are? That's the Board Room. @thehistoryguy should know, he's been filmed in it, but still talked rubbish about Room 40. The red lines? The Chief of the Staff's office. In orange? The war room. 2/
The light blue lines are where the Director of Intelligence Division (later DNI)'s office was (he later moved next door). Pink is Alfred Ewing's office where the codebreaking effort began. Dark blue is where the First Sea Lord moved his office later in the war. 3/
