Fifty Shades Of WWII Grey: Racy wartime affair between Brian Thomas Swansea surgeon and nurse Katie Walker from Hereford Swansea-born doctor Brian Thomas met nurse Katie Walker in Austria He was already married so returned to England to file for divorce They began their courtship by writing 300 love letters to each other Some very racy, and include references to spanking and new knickers They finally married after the war and settled in Hereford Their daughter Loraine Fergusson, 61, found letters when Katie died Has chronicled romantic wartime letters in blog A passionate wartime affair between a surgeon and a young nurse has been revealed, after their daughter found 300 secret love letters hidden in a chest of drawers. And some of the letters - which talk openly about spanking and new knickers - could be straight out of racy modern novels such a EL James' Fifty Shades Of Grey. Dashing Swansea-born doctor Brian Thomas met nurse Katie Walker during World War II, when the pair were posted in Graz, Austria, and fell in love instantly. They vowed to write to each other every day when they were parted. The look of love: Medic Brian Thomas and nurse Katie Walker met in Graz, Austria, and fell instantly in love Sealed with a kiss: The 300 romantic letters were found by Loraine, the couple's daughter, 60 years later at the bottom of a chest of drawers belonging to Katie More than 60 years later, 300 love letters written at the beginning of their courtship were found in Katie's bottom drawer by their daughter Loraine Fergusson, 61, after her mother died at the age of 88. Loraine waited three years before making their intimate letters public on a website dedicated to her parents' enduring love. Loraine, 61, said: 'The letters are a touching correspondence between two people who are clearly in love. But they also give an extraordinary window into life at the end of the war as men and women put their lives back together and strove to fulfil the dreams they had of a happy future. But things could have turned out very differently for the couple (and for Loraine) if it hadn't been for Brian's first wife meeting someone else while he was away at war... Happy together: When Brian and Katie met it was love at first sight, and the pair spent the rest of their lives together once Brian had divorced his first wife, Kit Brian had married his childhood sweetheart Kit just two weeks before being posted abroad with the Royal Army Medical Corps in 1942. Before proposing on a moonlit bridge in 1945, Brian confessed to Katie that he was still married, but promised to file for divorce as soon as he returned to Britain After a year tending to injured British soldiers in Algiers and the Middle East, Brian, then 34, returned home to discover his young wife had met someone else. Heartbroken, he returned to his duties in Italy, then to Graz, Austria, where he met 23-year-old Katie. On both sides it was love at first sight. Before proposing on a moonlit bridge in 1945, Brian confessed to Katie that he was still married. But he promised to file for divorce - citing adultery - as soon as he returned to Britain, which he did eight months before the end of the war. Work colleagues: Brian and Katie met while work colleagues in Graz, Austria, during WWII Unrequited love: When Brian, left, and Katie, right, met, he was already married to his first wife Kit, who had cheated on him while he was away at war Katie stayed on in Graz for eight months, and it was then they began their daily correspondence - each of the 300 loving letters sealed with a kiss. One of the love letters to the young nurse he called by the pet name of Boofuls, says: 'My dearest adorable lovely Katie. Oh darling, you really are the most incredible wonderful person in all this wide world and you make me so terribly happy. I still can't (and never will) get over the incredible miracle of you loving me' 'I still can't (and never will) get over the incredible miracle of you loving me. All my life I dreamed of loving such a person as you - someone who would love me and say dear sweet things to me and make me feel happy inside. Oh darling dearest Boofuls, I do just adore you. Isn't it amazing that a love like we've got can actually make one happy though we're apart? 'That you should love me in spite of all the dreary snags I've got, just fills me with wonderment.' The snag was that Brian was a decent man and wanted to divorce his adulterous wife without bringing shame and embarrassment on her. Brian even went through the charade of checking into a hotel with an actress for the night, so that he could be blamed for the divorce. Ooh, mother! Loraine Fergusson filing through her parents' courtship love letters, 300 of which - and some rather racy - she unearthed from the bottom of her mother's chest of drawers after her death My dearest darling: A love letter written from Katie in Graz to Brian in London on 11 April, 1946 He kept Katie up to date with his meetings with solicitors in London while filling his letters with his declarations of his love for her - and the occasional racy passage. Boofuls, I loved a bit of your letter when you said you were building some special undies for when our future comes One says: 'Boofuls, I loved a bit of your letter when you said you were building some special undies for when our future comes. 'I'm sure they are lovely and I swear I'll handle you as gently as if you were a piece of Dresden china when you've got them on. And I promise we won't have a ripping time.' One of Katie's letters to Brian says: 'Darling one, it's just as well you aren't here as you would probably have to spank me hard - but what a heavenly spanking!' Most of Katie's letters reveal a young woman who was faithful to the man of her dreams, despite the attention of other servicemen posted far from home. Passionate penmanship: Brian and Katie's letters are long, colourful, entertaining and dotted with illustrations One of her letters says: 'We had a party in the Sisters' Mess last night. It was a very good one, everyone mixing in well and as there were about three men to every girl, we found ourselves somewhat of a social success. I told you how much I loved you, how much I missed you, and how much I just longed with all my heart to see you again and snuggle up against you until I feel that nothing can ever part us again 'Oh my darling one, how much I missed you, you can never guess, it's always so much worse when I am at a party and surrounded by people. Everyone became very merry at this party and it was a very late hour when it ended. I missed you so much, darling one, that I went for a walk by myself around the grounds, I went past our seat, the one that we sat on the night after your dance. I then went and leaned against the fir trees - the ones where we had our tasty photograph taken. I just stood there and had a chat with you my darling one. I told you how much I loved you, how much I missed you, and how much I just longed with all my heart to see you again and snuggle up against you until I feel that nothing can ever part us again. Growing old together: Brian Thomas settled with his wife Katie Walker in Hereford, where they brought up their children Loraine and Peter Love of her life: Brian worked as an orthopaedic surgeon at Hereford hospital until his retirement in 1975, and he died seven years later at the age of 72, leaving Katie broken-hearted Katie and Brian settled in Hereford where they brought up two children - Loraine and her brother Peter. After Brian's death in 1983, broken-hearted Katie kept every one of the letters, along with dozens of fading photographs, in a drawer at the family home in Herefordshire until she died in 2009 Brian worked as an orthopaedic surgeon at the city's hospital until his retirement in 1975. He died seven years later at the age of 72. Broken-hearted Katie kept every one of the letters, along with dozens of fading black and white photographs, in a drawer at the family home in the Herefordshire countryside until she died in 2009. Loraine was too upset to go through them until now but she has now started transcribing the letters and putting them in an online blog. A slice of history: Loraine was too upset to go through the letters immediately after her mother's death, but now, three years on, she feels ready to share them with the world Loraine, an author from Didcot, Oxfordshire, said: 'It was exciting because I didn't know what is in them. 'I am transcribing one every a day and learning a lot about the early stages of my parent's love affair. At times it can be a bit like reading Fifty Shades of Grey. At times it can be a bit like reading Fifty Shades of Grey The fact that my father was married and had to get a divorce makes it so exciting. It's something that strikes close to a lot of people's hearts. It's from a different era. They never seemed to get insecure or have any issues, despite being so far apart. My father died when I was 29 but there was never any doubt they were still madly in love with each other. 'As a child you take your parents' relationship for granted but I never heard them argue and they were always laughing. They cracked each other up, even towards the end. To my dearest darling Boofuls: A letter from Brian to Katie My dearest adorable lovely Katie A most wonderful long letter from you today. Oh darling, you really are the most incredible wonderful person and all this wide world and you make me so terribly happy. I still can't (and never will) get over the incredible miracle of you loving me. That you should love me in spite of all the dreary snags I've got, just fills me with wonderment. It does so very definitely for me. I miss you like hell all the time, but the very knowledge that there really is an usses makes me happy in a wonderful deep sure manner. I'm sure no one else has ever had an usses but with us it's a tangible thing. When I think of you my darling, I don't somehow think of you as a separate being. I think of you as a part of my conscious self and you and me and usses and it's always so vivid. It's all the things we've ever said and done, all the sweet things you said to me, all our funny lownesses and our belching and the way we look and the smell of you and the way we dance and all I think of you. All that and heaps more is only just a fraction of what our usses is to me, my darling one. As you said in your letter, the time it takes us to get finally together is a waste, but it's no longer frightening. Do you remember how afraid we were once that anything could change? Now I know it won't. I've never been so certain of anything in all my life as I am of my love for you darling, and you will never escape me now. You just ruddy well try, and see how I react! I will deal with you like the young girl from Bermuda, who thought she was shrewder. I was shrewder. She thought it was rude to be viewed in the nude (pardon me). But I viewed her, pursued her, and... You will never guess what I did to her when I caught her. I want to snuggle my face in your neck: A letter from Katie to Brian My dear, darlingest Brian This will be a very short note tonight my sweet, my mind is a little more blank than usual but I was missing you so much and I decided to have a weenie short natter to you before zizzing. Did you know that I love you, my darling? Because I do and tonight I am filled with a very quiet tender love. I would just give the world to curl up in your arms and snuggle my face into your neck - perhaps you would stroke my hair and I know I should feel more contented than ever in my life before - you could always calm me down in the most wonderful way when I was feeling irritable and grumpy. You are such a tender darling, always so sweet and gentle with me, much more so than I thought any man could ever be. If I close my eyes now I can feel you inside me.
