"The last surviving 'listener' who intercepted and passed Nazi messages on to Allied codebreakers at Bletchley Park has died. Alison Robins, 97, taught herself Morse code and German during the Second World War and stayed up all night eavesdropping messages from German submarines positioned around Britain's coast. The heroine, who served in the Women's Royal Naval Service, told her children 'anyone who thinks black coffee keeps you awake is wrong - the only thing that keeps you awake is the thought that if you fall asleep people will die.' The mother-of-three, who had seven grandchildren and eight great-grandchildren, passed away in a nursing home in Bristol. In her wartime career Mrs Robins dressed as a civilian and was tasked with passing on messages to Station X - later identified as Bletchley Park, Buckinghamshire. Mrs Robins rarely spoke about her years spent in isolated points around the coastline, intercepting messages from enemy fleets, but her daughter believes it was the most exciting time of her life. Her daughter Jill Hazell, 69, said: 'She was the last one left - very few had Morse code and German, there were only a handful of them. 'I think she must have been quite intelligent - she left school with almost nothing. 'She trained as a riding instructor and then when the war broke out she became a wren, and worked as a stewardess." Last Bletchley Park ‘listener’ Alison Robins dies | Daily Mail Online
