Notes for Maurice Llewelyn CLEMENT-JONES MA
Served in World War II; Eventually Major, Intelligence Corps. Excellent linguist. Worked on Enigma/Ultra material in Hut 3M at Bletchley Park during WWII where he met MJC-J. He retired from the position of Group Personnel Manager with Albright and Wilson (the then Chemicals Company) at the age of 58. Member of the Industrial Appeals Tribunal. On death of his mother ESJ sold Trevalyn Hall. Also sold Godmund Hall, Burneside, Kendal a gift from his father. Principal hobby carpentry at which he excelled.

Married by Michael Gresford-Jones then Vicar of St Botolph’s, Bishopsgate, City of London. Reception at the Grosvenor House Hotel.

Originally surnamed Jones, then name changed by his father in 1927/28 to Clement-Jones whilst he was at prep school.70

Both he and and MJC-J are on the Bletchley Park roll of honour. See

This is NTC-J’s summary of what he has discovered of his father’s war service:

“Dad was called up in July/August 1940 (having been rejected in 1939 because of his eye sight and told to take a teaching post at Malvern College) and sent to Ilfracombe, Devon with the Pioneer Corps. Arthur Koestler was clearly the only person worth talking to. He was there until February 1941. When he finished he was a corporal and for a short time at the end an acting sergeant.

The story about being plucked from the ranks by Lord Reading is almost certainly apocryphal. He certainly met Lord Reading and on one occasion acted as a translator for a French man-ex-legionnaire - on a drunk and disorderly charge! Reading was the presiding officer and clearly spoke good French although not as good as Dad's.

Apparently a friend of Grannie and Grandpa's wrote to Lord Reading suggesting that Dad should get a commission directly from the Pioneer Corps. In the event that did not happen but it is clear that it helped get him on to the officers course.(the OTCU) Even at this stage he was hoping to get into the Intelligence Corps but they had him down for a machine gun regiment and a possible transfer at a later date.

Dad then went to Droitwich in March 1941 to join OCTU and then to Lanark from where he was commissioned in September 1941. Sadly there are no letters thereafter.

I am still perplexed as to what he did from then until Bletchley Park which I was told was January 1943. Maybe he did do a spell with the infantry regiment. Alternatively he may have been with the Intelligence Corps but not at BP.”


From Wikipedia:

Hut 3 was a wartime section of the Government Code and Cypher School (GC&CS) at Bletchley Park tasked with the translation, interpretation and distribution of German Army (Heer) and Air Force (Luftwaffe) messages deciphered by Hut 6. The messages were largely encrypted by Enigma machines.

Located initially in one of the original single-story wooden huts, the name “Hut 3” was retained when Huts 3, 6 & 8 moved to a new brick building, Block D, in February 1943.[1] Then the decodes from Hut 6 for Hut 3 which had been sent in a wooden tray from one hatch to another via a wooden tunnel between the huts were sent from the Hut 6 Decoding Room by a conveyor belt that “never stopped”

Operation

The Enigma “Red” cypher was the main cypher used by the Luftwaffe in every theatre where they operated. Red had been broken sporadically from the beginning of 1940, and from 22 May BP overcame some changes to the Enigma machines. From then on, Hut 6 broke Red daily to the end of the war, and it became the “constant staple” of ULTRA. Calvocoressi wrote that later in the war “we in Hut 3 would get a bit tetchy if Hut 6 had not broken Red by breakfast time.” [3]

Initially there were only four people in Hut 3, and there were serious personal frictions between them. They were the original leader Malcolm Saunders (Squadron Leader, RAF), Robert Humphreys (senior liaison officer with the Air Force), Captain Curtis (senior liaison officer with the War Office, who knew no German), and Cambridge academic F. L. Lucas who had been in the Intelligence Corps in WWI.[4] Humphreys was “an excellent German linguist, but no team player. He wanted to get his own way. He found this difficult to do if only because Saunders had a mind of his own. Nigel de Grey described the situation as 'an imbroglio af conflicting jealousies, intrigues and differing opinions'. Initially Travis moved the three out of Hut 3 and put a small committee including Eric Jones in charge. As this did not work, Jones was made sole head in July 1942. Just over a year after he took over, H. S. Marchant was made his deputy, and the pair were in charge to the end of the war.” [5]

Army and Air Force Ultra was distributed by the SLUs (Special Liaison Units)] set up by Frederick Winterbotham. By the end of the war there were about 40 SLUs to 40 commands. Signals were given a priority from Z to ZZZZZ (the highest of 5), and about 100,000 signals were sent to commands during the war [6]

The rules of interpretation for Hut 3 were that if the text was not explicit the Hut 3 officer could not add his interpretation without qualification; for a 1944 SS Panzer message where the placename had been missed or corrupted when received, the officer did not say simply “Dreux” but would say “slight indications Dreux” or “fair indications Dreux” or “strong indications Dreux”.[7] They could also add glosses preceded by the word “Comment”.[8]

The Air Index had “hundreds of thousands” of cards about 5 by 9 inches; so important that they were photographed and stored in the underground stack of the Bodleian Library in Oxford in case they were destroyed by bombing. Run by “about two dozen girls” and a man who was a “strange genius”, it had cards for every individual, unit, place or equipment so that any previous reference to (say) Major So-and-So could be found. There were two card indexes, 3A & 3M.
Notes for Margaret Jean HUDSON
Worked at barrage balloon centre at Sutton outside Hull as telephonist and then trained others.Trained at Uxbridge and then Leighton Buzzard to plot and passed out as one of the first members of the WAAF. Then Fighter Command at Stanmore (Bentely Priory) 1939-40 (Dowding was head of fighter command then) but then left the airforce because mother was ill. Worked for Company Secretary of Reckitts. Saw the bombing of Hull. And then took a job as a civilian in Hut 3 Bletchley Park from 1941 (where decoded Enigma messages were translated) where she met MLC-J. Hut 3 is still standing and part of the Bletchley Park Museum.
