Room 40’s Greatest Triumph
This time line is a What If scenario, as a student of Military Intelligence, I have spent many a long hour reading up on the origins of MI6 & MI5 founded in a small offices under the leadership of Mansfield Cumming-Smith (C) and Vernon Kell. However, one section of the story of the origins of modern intelligence is from the office of Naval Intelligence. Specifically Room 40, and the success of William (Blinker) Hall the director of naval intelligence.
Room 40 had immense luck in the early days of the war, with the miraculous draft of Fishes, the Magdeburg & the Hobart. All 3 German code books fell into British Hands within the first 6 months of the war and with the severing of German Telegraph lines days into the war Room 40 was able to read all traffic that was coming from the German fleet both military and merchant.
Room 40’s success is seen the most through the Zimmerman telegram which was instrumental in bringing the USA into the First World War. One of their greatest failures however was during the battle of Jutland, specifically during the opening days. Where (as I view it) one officer, Cpt Thomas Jackson badly underestimated Room 40’s cryptographers and stormed into Room 40 and demanded to know what the signal code DK meant, and was told that it was Admiral Sheer’s call sign in Harbour. He then stormed back out without seeking clarification of this; if he had he would have known that when Sheer sailed from the Jade he transferred DK to a signalling station within the Jade.
And Thus DNI reported to Beatty and Jellicoe that the HSF was not at sea but rather still in port and that only the Battlecruisers had gone out on a sortie, so Jellicoe and Beatty got some real shocks when the reports of the HSF was at sea were reported from HMS Southampton during the battlecruiser engagement. This Failure was compounded later on in the battle when DNI accurately reported the HSF’s location and route home and Jellicoe ignored this information due to failures in intelligence earlier in the day.
This timeline is a what if, What if Jackson had turned around and gotten the full picture from the men in Room 40. And the Grand Fleet was fully ready for the battle and was able to engage the HSF for the Night Action of Jutland.
This is my first Alternative history time line, inspired by people like Calbear, Astrodragon & Devolved so please be kind.

Captain Thomas Jackson was having one of those days, dozens of reports of U-Boat movements and now there had been intelligence for the last few days that the High Seas Fleet was planning a Sortie. The question was when would Sheer sail. The Grand Fleet was at sea, and yet they had nothing to confirm whether the High Seas Fleet was already at sea. Thankfully there were no U-Boats in the vicinity of the Grand Fleet. But now they had something, the signal from the Jade bearing the call sign DK. What did that mean? Pushing the doors to Room 40 OAB open startled the intellectuals and mathematics professors within. Walking up to the desk of the nearest former Oxford Professor he placed the signal upon his desk.
"What does the signal code DK signify?"
The Professor looked up at him blankly as if being asked where the nearest heads were.
"It's Grand Admiral's signal code when he and the flagship are in Harbour."
Jackson sneered and spun around, disappointed bitterly the High Seas Fleet was still in harbour, only Hipper’s Battlecruisers were at sea, if that. Walking from the room though he paused in the doorway and shuddered for a moment He remembered a comment, written snidely in a report by one of those tweed wearing pipe smoking insubordinate civilians. Turning he called back to the professor who was turning to his colleagues and shrugging his shoulders.
"Is there anything else to the signal code?"
The professor looked surprised at actually being spoken too with a genuine question rather than a demand.
"Of course, when Sheer and the flagship have gone out on a sortie he transfers the call sign DK to a signalling station within the Jade River."
Jackson‘s eyebrows raised, had he understood that correctly. DK was simply a signalling station within the Jade River right now, not the Flagship of the High Seas Fleet?
"So the High Seas Fleet is at Sea?"
"Yes"
Jackson spun around and ran out of the doors, he had to tell Blinker this, the High Seas Fleet was at sea, the great battle between Dreadnoughts was going to happen at last.

Admiral John Jellicoe looked at the scrap of paper in his hands that had just been handed to him, he already felt the weight of the world upon his shoulders as he looked up and around at the massive forms of the largest fleet ever assembled by an Empire. And now he had a chance to use it in battle. He handed the piece of paper across to Cpt Dryer who took the scrap and read it to himself.
