Stonehouse saved his own life by drawing sketches for the camp commandant, guards and their families. Throughout his time in five prisons, Stonehouse kept his personal vow of never painting or drawing an officer in uniform. At the camp he witnessed the arrival of four female SOE agents, Andrée Borrel, Vera Leigh, Diana Rowden and Sonya Olschanezky, who were all executed and disposed of in the crematorium to make them disappear without a trace, under the programme of "Nacht und Nebel" ("Night and Fog"). After the war, Stonehouse and Guerisse were able to testify at the Nazi war crimes trials as to the women's fate. In 1985, Stonehouse painted a poignant watercolour of the four women from memory which now hangs in the Special Forces Club in London. From Natzweiler-Struthof, Stonehouse was sent to the Dachau concentration camp from where he was liberated by U.S. troops on 29 April 1945. At home, he was awarded a military MBE. After the war, he remained in the military and was promoted to captain while working for the Allied Control Commission in Frankfurt, Germany where he assisted with the interrogation of Gestapo and SS members. Post-war After 1946, Stonehouse continued his career as a fashion artist in the United States, painting for magazines including Vogue, Harper's Bazaar and Elizabeth Arden. In 1979, he returned to Britain and became a portrait painter. His clients included members of the Royal family. One of his last portraits of The Queen Mother, who sat for him many times, still hangs in the Special Forces Club in London. During his final years Stonehouse was an active Theosophist living at the London branch of the United Lodge of Theosophists. Brian Stonehouse's art Whilst operating in France Stonehouse continued to sketch and draw people he came across. He was on several occasions told not to carry his sketch books with him whilst 'on duty' (Interview with his surviving brother, May 2007). Throughout his times in various prisons he continued to draw, at first secretly, but after discovery more openly. His collections of drawings of fellow SOE prisoners, life in prison and prison guards along with other personal artefacts was handed over by the Stonehouse Family to the Imperial War Museum London in May 2007. These included, as well as the War Art, for example, postwar letters from surviving SOE operatives and letters and photographs from US President Dwight D. Eisenhower.
