On 21 June 1940, the German Army invaded Concarneau and Marcel and Diana's house was requisitioned. The German Army started the process of moving everybody over the age of sixteen away from the coast, so Lyon-Smith was sent to a convent in
Châteauneuf. After an ear infection, Lyon-Smith was taken to hospital in
Quimper. In December 1940 and while still in hospital, she was interned along with her nanny and other British subjects to a camp on the outskirts of Quimper, then taken by train and lorry, along with many hundreds of other people to the
condemned internment Camp (Konzentrationslager) at
Besançon (
Frontstalag 142 or Caserne Vauban). At the end of 1940, 2,400 women, mostly British, were interned in the barracks, along with 1600 other nationalities, in a camp suitable for only 2000 people. In March 1941, Lyon-Smith was released after the
Red Cross visited the camp. She moved to a
pension in
Neuilly and told to report to the local police station every morning. During the freezing winter of 1941-1942, Lyon-Smith caught
pneumonia. While in Neuilly, Lyon-Smith enrolled in a school under a false name, at Cours Montaigne, where she sat the Pre-Baccalaureate and passed.
Escape from Paris In July 1941, Lyon-Smith's cousin Diana was able to procure false identity papers, the ''carte d'identité
under the name Maria Cormet'', Lyon-Smith initially denied being Lyon-Smith, stating that she was Savier, even though her school books had been seized and they were tagged with her real name. She eventually admitted to being Lyon-Smith, as her French was not good enough to maintain the pretense of being a French schoolgirl and was subject to continual interrogation over months. Shortly after her arrest, Lyon-Smith caught a skin disease on her back that was not amenable to normal treatment. Over several weeks, Lyon-Smith slowly formed a dependent relationship with interpreter Karl Gagel, who wanted to marry her. Gagel was always present at the interrogations to translate Müller. Lyon-Smith pretended it was a romantic relationship with Gagel, to ensure she received preferential treatment. Gagel persuaded
Heinz Pannwitz, chief of the Sonderkommando Rote Kapelle to allow Lyon-Smith to attend the surgery of a doctor in the local neighbourhood for treatment. As the months passed, passing Christmas into the spring of 1944, Lyon-Smith's condition worsened, as the doctor's treatments failed. By March 1944, Lyon-Smith was seriously ill. On 13 March 1944, she was released on leave of parole, after managing to satisfy the Gestapo that she had no connection with the
French Resistance. Lyon-Smith was instructed by Pannwitz to stay with Diane Provost. In April, Lyon-Smith received a phone call from Gagel, which scared her, but she agreed to meet him, and later agreed to meet him once or twice a week to avoid reprisals. At the end of July, Gagel informed Lyon-Smith during a phone call that the Gestapo was leaving Paris and that they should meet to say goodbye, threatening her with the knowledge that he had his service pistol with him.
Liberation After the
Liberation of Paris on 25 August 1944 Lyon-Smith received a visit from her father, whose division was fighting to the north of Paris, and who arranged for her to fly home to Great Britain. Arriving in London, Lyon-Smith took a train up to Glasgow where she met her mother on the platform of
Glasgow Central Station. Phyllis Lyon-Smith had lived in a hotel in
Ayr for the duration of the war and worked as a member of the
Royal Voluntary Service. After recovering, Lyon-Smith joined the
Women's Royal Naval Service (WRNV). ==After World War II==
