'Decoding the war' : Letters to The Telegraph, 'Y' service

Decoding the war

SIR – The story of Alan Turing and his team at Bletchley Park is very 
interesting, but it is only part of the story.

The origins of decoding can be found in the First World War, when wireless 
was in its infancy. Mata Hari, the Belgian courtesan and dancer, was 
caught by a wireless operator passing vital information to the Germans. 
She was tried and shot. Winston Churchill heard about the incident and 
encouraged the Armed Forces to set up wireless intercepting units.

My father was a railway telegraphist and a 1914 volunteer to the Army. The 
First World War ended and he came home safely. In 1938 he responded to the 
government’s appeal for civilian wireless enthusiasts. He was interviewed, 
signed the Official Secrets Act, and was accepted, becoming one of 1,600 
top-secret civilian “Y” outworkers around the British Isles. Bletchley 
Park became top secret station “X”.

As a family we knew nothing of this. I remember hearing the Morse code 
sounds, wireless whistles and shushings coming from under the stairs and 
thinking it was Dad’s hobby.

The First Bletchley Park : New exhibition reveals the secrets of Room 40

The First Bletchley Park : New exhibition reveals the secrets of Room 40 
where codebreakers became the hidden heroes who won World War One

- Room 40, the Government's top secret listening post, paved the way for 
  the Government Code and Cypher School
- That school was based at Bletchley Park, where codebreaker Alan Turing  
  was based during World War Two
- Admiralty intelligence department decoded Zimmerman telegram, which 
  proved German's hostility to the US
- Exhibition marks role Room 40 - where legendary codebreaker Dilly Knox 
  worked - had in ending World War One

By Steph Cockroft for MailOnline

The fascinating work executed by genius codebreakers at Bletchley Park 
during World War Two is now the stuff of legend, thanks in no small part 
to Benedict Cumberbatch's performance in the award-winning Imitation Game.

But perhaps the most crucial - and relatively untold - story in Britain's 
codebreaking history is that of Room 40, an organisation which intercepted 
and deciphered a series of German messages during World War One which 
dramatically changed the course of the bloody conflict.

The organisation, the Government's top secret listening post, carried out 
decoding work which paved the way for the the now-famous Bletchley Park, 
where crucial intelligence exploits was carried out behind closed doors to 
defeat the Nazis.

OBITUARY : Ruth Sebag-Montefiore

- Sebag-Montefiore worked as a coder at Bletchley Park during the war

Matriarch of the prominent Anglo-Jewish family who wrote a revealing
memoir about the vanished age of her childhood

“Always damp your forehead with sea water before bathing,” the young Ruth
Magnus was advised soon after the First World War. Other pearls of wisdom
she recalled included “never eat lettuce in France” and “never pick
blackberries low down” — this last drummed into her by the nurserymaid, a
farmer’s daughter from Kent.

In time, she became the matriarch of one of the leading Anglo-Jewish  
families, the Sebag-Montefiores, and, through her published memoir and
lectures, a repository of knowledge both about her forebears and the
nowvanished age of her childhood....

'There is no longer an enemy to defeat' : Remarkable final intelligence 
report from the last day of WW2 and a historic telex from Eisenhower 
announcing the German surrender up for auction

- Final Allied intelligence report of World War Two has emerged 70 years

By Sam Tonkin For Mailonline

The final Allied intelligence report of World War Two stating that 'there 
is no longer an enemy to defeat' has emerged 70 years on along with an 
historic telex announcing the German surrender.

The intelligence summary came from the Cipher Office of the Allied forces 
which reported back to army top brass of any enemy movement in Europe 
after the Normandy invasion in June 1944.

In the last top secret message sent from the office on May 8, 1945 - VE 
Day - the document reads: 'For the first time in 11 months there is no 
contact with the enemy..../snip/

Used by Nazis, cracked by Turing, sold by Sotheby's : 
Rare surviving Enigma machine expected to fetch £70,000 at auction

- Enigma 1, known as Wehrmacht or 'Services' Enigma, dates from 1930-38 
- It was used by German military and also railways before and during war
- Machine is one of earlier models with just three rotors; later ones 
  had five
- About 100,000 Enigma machines were made until the fall of Third Reich
- Few survived as Germans tended to destroy them as they retreated
- Codebreakers led by Alan Turing worked to decipher Nazi machines at 
  Bletchley Park

By Nick Enoch for MailOnline

A rare early German Enigma machine that WWII codebreaking hero Alan Turing 
worked hard to decipher is to go under the hammer.

The Enigma 1, which dates from between 1930 and 1938 is also known as the 
Wehrmacht, or 'Services' Enigma, and was used extensively by German 
military services and other government organisations such as the railways 
before and during the war.

How Turing solved the enigma of Solitaire (fwd)

06 June 2015

How Turing solved the enigma of Solitaire : Codebreaker's letter to girl, 
8, explains how to crack the game ( and here it is for anyone who's lost 
their marbles trying to solve it )

- Alan Turing wrote to Maria Greenbaum in 1953 with advice on Solitaire
- Aim of the game is to leave a single piece at the centre of the board
- But Turing knew the game could end with pieces scattered around 
- Letter expected to fetch up to £60,000 when it is auctioned later this 

By Chris Hastings for The Mail on Sunday

It is the parlour game that has been maddeningly frustrating to 
generations of players over the years.

Though the basic rules of Solitaire are simple – a marble is removed from 
the board after the player ‘jumps’ another over it – the aim of leaving a 
single piece at the centre of the board can prove baffling.

But one of the most brilliant minds of the last century devised a solution 
to help a young child play it.

Alan Turing, famed as the great intellect who broke the Nazis’ Enigma code 
during the Second World War, explained his Solitaire method in a letter to 
a girl who was a family friend.

Maria Greenbaum was the niece of Turing’s therapist, and was aged eight 
when she received the letter. It is expected to fetch up to £60,000 when

Wartime Wren who was sent to Bletchley Park to work with the codebreakers
Hilary Bedford was a bad-tempered photographer who was decorated late in
life for her work at Bletchley Park with Alan Turing — after keeping it a

In 2009 Bedford walked into the offices of her local newspaper in north
London carrying a small blue box. Inside was a medal from Gordon Brown,
the prime minister, for her service at Bletchley Park.

As a 17-year-old she worked on the Bombe — the top secret “thinking

How Alan Turing's secret notebook could disappear forever

He was one of Britain's finest minds, the father of modern computing, but
his troubled life and classified wartime work meant his legacy was
neglected for decades. As the world finally recognises his brilliance, Rob
Crilly reports on how a hidden manuscript is to go on auction amid fears
it may be snapped up by a private collector..../snip/
