Mavis Batey

Mavis Lilian Batey,

I was concentrating on

German romantics and then I realised the German romantics would soon be overhead and I thought well, I really ought to do something better for the war effort.^[5]

She decided to interrupt her university studies. Originally, she applied to be a nurse, but discovered that her linguistic skills were in high demand.[6]

Codebreaker

At first she was employed by the London Section to check the personal columns of The Times for coded spy messages.^[7] Then, in 1940, she was recruited to work as a codebreaker at Bletchley Park.^[2] She worked as an assistant to Dilly Knox, and was closely involved in the decryption effort before the Battle of Matapan.^[8][9][10] According to The Daily Telegraph, she became so familiar with the styles of individual enemy operators that she could determine that two of them had a girlfriend called Rosa. Batey had developed a successful technique that could be used elsewhere.^[11]

Although Batey was just 19, she started working on the

Apart from being a talented code-breaker (he had broken the Zimmermann Telegram in World War I), Knox was a noted classics scholar, and wrote a poem to celebrate the Allied success at Matapan. He included a stanza dedicated to Batey and the key role she had played in the victory:

"When Cunningham won at Matapan, By the grace of God and Mavis, 'Nigro simillima cygno est,' praise Heaven, A very 'rara avis.' " ("Like the black swan, she is, praise heaven, a very rare bird".) It was, she later said, "very heady stuff for a 19-year-old".^[14]

In December 1941 she broke a message between Belgrade and Berlin that enabled Knox's team to work out the wiring of the Abwehr Enigma, an Enigma machine previously thought to be unbreakable.^[4] Later, Batey broke another Abwehr machine, the GGG. This enabled the British to be able to read the Abwehr messages and confirm that the Germans believed the Double-Cross intelligence they were being fed by the double agents who were recruited by Britain as spies.^[1]

While at Bletchley Park she met Keith Batey, a mathematician and fellow codebreaker, whom she married in 1942.^[2][15]

Publications

Mavis Batey wrote a biography of Dilly Knox: ‘Dilly: The Man Who Broke Enigmas’. The book gives a summary of the government codes and cypher school's codebreaking operation in Bletchley Park. It also describes her code breaking of the Italian Enigma which contributed to the British Navy's success at the Battle of Cape Matapan.^[12]

Later life and awards

Batey spent some time after 1945 in the Diplomatic Service, and then brought up three children: two daughters and a son.

Batey, a widow since 2010, died on 12 November 2013 at age 92.[1]^[4][19]

In 2005, The Gardens Trust held the first Annual Mavis Batey Essay Prize, a competition geared towards international students who are enrolled in a university, institution of higher education or who have recently graduated from one.^[20] The award celebrates Batey's achievements and advocacy in gardening.^[20]
