Insight into one of ‘The Bletchley Girls’


Tessa Dunlop is the Author of The Bletchley Girls (Hodder & Stoughton 2015) and To Romania with Love (Quartet 2012). She is currently doing a PhD at Sheffield Hallam on Romanian identity during World War I, having been awarded a scholarship. She can be seen hosting history documentaries including BBC2’s Coast, and heard on Radio Four’s ‘Crossing Continents’ series among others – including a one-off half hour called ‘The Bletchley Girls’.


In this post, Tessa Dunlop writes about her conversations with ninety-two year old Rozanne Colchester. Sipping tea in Oxfordshire with a former vicar’s wife, Tessa soon uncovers the most extraordinary backstory. Rozanne not only worked in one of Britain’s most iconic organisations – Bletchley Park, but as a teenager she also had a front row seat in continental Europe, where Fascist Italy was gearing up for war…

An Unlikely Asset

Rozanne in her teens.

‘I had never been abroad before, we went on a train. It was a terrific adventure – the wonderful mountains at night and waking up in the morning having arrived in Rome!’

Long gone was the Yorkshire vicarage with its abundant garden; now Rozanne at a peachy 15 was deemed old enough to accompany her father to his latest posting. Charles Medhurst was appointed the British Military Attaché in Rome with a mission to monitor Italian rearmament. But to hear Rozanne reminisce it is easy to forget that the fascist state was moving inexorably towards war. She loved her time in Italy; the weather, the language and the people. From her school girl perspective the adventure has a naive, occasionally comical quality.

She was soon familiar with Mussolini – or Musso as Rozanne refers to him. On their way to classes satchels swinging, all legs and smiles, she and her sister walked passed his Villa Torlonia. ‘Oh he used to come out at a certain time, just when we were going to school and wave at us.’ The Duce was very fond of girls. ‘Ha! He was rather a figure of fun among our friends, he took himself very seriously. He would put on a face, throw out his jaw and march about which was ridiculous. It was ridiculous that the Italians tried to copy Hitler. Middle-aged fat men full of spaghetti trying to do the goose step at the head of their troops. It was the funniest thing!’

At ninety-two Rozanne remains an adept storyteller. She leans in. ‘I even met Hitler! I shook his hand.’ As a family member of the British diplomatic mission 16 year old Rozanne was there, waiting on the platform when in May 1938 Hitler and his circus of 500 Nazis arrived to woo the Duce. ‘He looked much more normal in the flesh than I imagined.’ Rozanne shuts her eyes, briefly his man’s hand is back in her slender, innocent clasp. Then the moment passed. Mussolini had arrived and the military parade began. ‘Gosh yes! And you know Hitler looked much more normal in the flesh, I had imagined a Charlie Chaplin type figure with a black moustache. But he did have fanatical blue eyes, I remember them vividly.’ It was all so surreal, something of a game, but then Rozanne was only a child; a helpless bystander flanked by the glistening edges of an ugly undercurrent.

Italy entered the war in 1940. Rozanne went back to Britain. The lights were out in Paris, a solitary solider stood guard in their Channel ferry. ‘One wondered if one would see a battle.’ But Rozanne didn’t. Ducking bombs under a dining room table in Kensington was deemed too risky, soon she had been bundled off to Yorkshire where she killed time as a typist for Northern Command. A slip of a girl, told off for wearing slacks to work by a harridan, it all felt rather pointless. Her brother was training to be an airman, her sister worked in Baker St (‘very hush hush’) and her young beau was already dead; midshipman David Bevan had been torpedoed in the Mediterranean in the summer of 1940. ‘After David and Blitz I was longing to be involved. From then on one was longing to be old enough to get in the Services. The Air Force was in my blood, I was going to join the WAAFs’

But although conscription for women was poised to demand it of her, square-bashing in a uniform would’ve been a waste. Rozanne had a vital skill, honed in view of the Tiber river, practised in the Borgais Gardens, chirped in response to Musso’s cheeky acknowledgements. She could speak Italian. Her father had been promoted to head of Intelligence at the Air Ministry and, aware his daughter possessed a valuable national asset, duly intervened. ‘Father explained to me there was a place called Bletchley Park and they needed Italian speakers there.’

In 1942, equipped with school girl Italian and a scarlet bicycle, Rozanne entered Britain’s most secret organisation. With typical modesty she plays down her role at Britain’s giant code-breaking centre. It was all so unlikely, on the flats of Buckinghamshire, teeming with girls just out of school, mushrooming huts and blocks, a conveyor belt of corridors, closed doors, and classified information. Rozanne still enjoys recalling the peculiarities of the place, in particular the friendships she made – an Oxford Don twice her age and a professional actress whose à la mode style caught her eye – but what she actually did at this Park, a mere cog in a giant wheel, is harder to grasp.

That was deliberate.

The less said the better; unnecessary information endangered lives. Rozanne furrows her brow. She was in the Italian Air Force Section. Under orders from Hitler, in March 1941 General Rommel’s Afrika Korps arrived in Libya to bolster the flaying Italians. The subsequent war in the desert was a protracted bloody affair and the interception and decoding of high grade Italian Air Ciphers proved invaluable. Far removed from the action Rozanne was hunched over ‘reams of paper, girls would bring in great bundles in haversacks.’ She shakes her head. ‘I was a decodist; there was a technique you learnt to break the code. It was quite specialised. You tried out various numbers until bits of words started to make sense. A lot of it was humdrum stuff.’ Rozanne waves her hand dismissively. She is keen to underline the more important men who surrounded her.

The days streamed past in a haze of shifts. ‘When we began work there was silence and total concentration. ‘ Then a tea break of ten minutes after two hours was followed by ‘work and a concentrated silence again.’ A young girl, albeit one who spoke Italian, Rozanne might have slipped through the war unaware of any specific mark she had made against an enemy she knew personally. Much of Bletchley Park’s intelligence was based on the forensic decrypting and ordering of thousands of enemy messages, Rozanne was a part of this vast process. Her elementary decoding skills helped uncover general patterns of communications and confirmed logistical information. Not quite the noble war she had longed to fight, not really what she had imagined. But then, war is unpredictable.

Rozanne was working late. It was 1.30 in the morning and with the exception of Joe Hooper (later head of GCHQ) she was alone. It is easy to imagine her, gamine and pretty in a modest jersey and skirt, pearls resting on the nape of her long neck, head poised and attentive. ‘I was decoding a message freshly arrived on the teleprinter. After many trials and errors … the ‘groups’ of numbers began to make sense, yes, and I found myself faced with a message that made sense.’ Staring back at Rozanne in the middle of the night was an important Italian message she had personally unpicked. In a small room in Buckinghamshire she was reading something no one else in the Allied Forces knew. In 3 and a half hours time at 4am, Italy’s SM.79 Torpedo Bombers and SM.82 transport carriers were due to leave Tripoli and head across the Mediterranean.

‘Imagine the thrill! I told Joe Hooper about the message and he leapt from his desk in wild excitement. He tore along the passage to Josh Cooper’s room. With the Desert War over in early 1943 the crippled Italians were heading for Sicily, but thanks to Rozanne they never reached their final destination. ‘It was the only time I did something useful in all the years I was at war. The whole place was alive with excitement. I got a pat on the back!’ A rare accolade for a humble Bletchley girl.

And then suddenly, towards the end of her euphoric story Rozanne’s face crumples, she looks anxious, almost scared. ‘It was awful, terribly sad to think of all those Italians being shot down. I lived in Italy, they were my friends.’ Sunshine and silly old Musso, Italian mamas, pasta and pavement cafes, it all comes flooding back. Rozanne had fired a lethal shot into the heart of Italy without leaving her desk in England. Seventy one years on, the young triumphant girl long gone, Rozanne is fleetingly revisited by the confusion of war and her own part in it.

She shudders. ‘I loved the Italians but I’m jolly glad we won the war.’
