Government Code & Cypher School (and a hidden message)

During World War I the British Army and Royal Navy both had separate intelligence agencies. Military Intelligence 1b, MI1(b) and Naval Intelligence Department 25, NID25, respectively. NID25 was initially known as Room 40, or 40 O.B., with O.B. referring to 'old building'. 

Following the conclusion of World War I the Cabinet's Secret Service Committee recommended that a peacetime codebreaking agency should be created. Lord Curzon, chairman of the Cabinet's Secret Service Committee, tasked Hugh Sinclair, Director of Naval Intelligence, with creating the new department.

Hugh Sinclair merged staff from NID25 with MI1(b), with the new agency consisting of between 25-30 officers, with roughly the same amount of clerical staff. Victor Forbes, of the Foreign Office, chose the cover-name 'Government Code & Cypher School (GC&CS).

The Government Code & Cypher School moved into Watergate House, Adelphi, with the Admiralty's Alastair Denniston, previously an NID25 officer, as its operational head. 

Its public directive was "to advise as to the security of codes and cyphers used by all Government departments and to assist in their provision". However, it also had a secret directive: "study the methods of cypher communications used by foreign powers".

Although officially formed on November 1, 1919, the Government Code & Cypher School produced its first decryption on October 19, 1919.

In 1921 the offices moved to the Broadway Buildings, opposite St James's Park, in the same building as the SIS, and came under the supervision of Hugh Sinclair. At the time Hugh Sinclair was Chief of SIS and Director of GC&CS.

On February 14, 2019, HM Queen Elizabeth II unveiled a City of Westminster plaque to mark the centenary of GCHQ.

However, keeping with the codebreaking, communications and cypher work of GCHQ, the plaque contains a hidden message, which most people don't even realise. 

Can you uncover the hidden message?

If you can't figure it out, there is a clue below. 

Various characters, on the plaque, have a dot or dash beneath them. 

If you find them all it reveals the message...

"1 HUNDRED YEARS"

So, did you work it out, or did you cheat?

Warships on the River Thames

HMS Belfast, the Tower of London and Tower Bridge (2018).

Over the centuries the River Thames has seen many ships cruise her waters. Some of these ships were built in Deptford, or one of the other shipyards along her banks, while other ships were broken up on the banks of the River Thames, when they were decommissioned. 

Since the end of World War II, with the creation of NATO, ships from various navies from a myriad of NATO powers have visited London, often mooring at Greenwich or Canary Wharf docks, while others go upstream and moor next to HMS Belfast (C35).

Below are just a few of the Naval ships that have visited the River Thames.

HMS Belfast from The Shard (2019).

HMS Belfast played a major role in the sinking of the German Ship, Scharnhorst, in 1943, before taking part in the D-Day landings in 1944, where she was one of the first ships to open fire. Her guns were so powerful that, when fired, they cracked the toilet bowls onboard.

She was intended to become a museum, much like HMS Belfast, but all the bids fell through as the upkeep of the 22,000-ton ship was not feasible, and so was sold for scrap in 2016.

HMS Illustrious at Greenwich

HMS Illustrious at Greenwich.

Monday May 13, 2013.

Recently, HMS Illustrious arrived in Greenwich to mark the 70th Anniversary of the ‘Battle of the Atlantic’. She was berthed at Greenwich, just to the West of the Cutty Sark and the old Royal Naval College. Not having been to London, for a while, I thought it would be nice to see her off and get some photographs. HMS Illustrious was due to depart Greenwich at 15:30 and head around the Greenwich Peninsula and on through the Thames Barrier, so I headed to the O2 Arena to see her.

I arrived at North Greenwich just after 15:15 and made my way to the River Thames, just East of the Emirates Cable Car, where I had a great view of the O2 and the Thames Barrier. Patiently, I waited. And waited. Deciding that I had either missed her, or that she was running late, I took a cable car across to the Royal Victoria Docks, so that I could look westward to see if I could spot her. Sure enough, there she was.

After getting another cable car back to North Greenwich, I took a Thames Clipper to Greenwich. As we approached I managed to snap a quick shot of HMS Illustrious’ Port side, before disembarking from the Thames Clipper. I strolled along the embankment, stopping every now and again to take a photo. I then took a detour, due to a new housing complex, which brought me out behind HMS Illustrious, giving me a great view of the ship and the Old Royal Naval College. 

Security aboard HMS Illustrious.

With time getting on I decided to walk to Canada Water, where I could catch a train back to Baker Street and from there a Metropolitan train to Watford.

On arriving at Baker Street, I realised that there was quite a wait for my next train, so I wandered up to street level and visited one of the tourist shops, to buy Erin a present. After a quick look around I settled on a plastic pink glass with a curly straw. I then headed into the ‘Metropolitan Bar’ for a quick drink, before catching my train home.

Even though I never got to see HMS Illustrious sailing out to sea, she was still a marvel to behold.
