Lefort. She was killed in the gas chamber sometime in February 1945. Forty-one female Section F SOE agents served in France, some for more than two years, most for only a few months. Twenty-six of them survived World War II. Twelve were executed including Szabo, one was killed when her ship was sunk, two died of disease while imprisoned, and one died of natural causes. Female agents ranged in age from 20 to 53 years. Awards and honours Szabo was the second woman to be awarded the George Cross, bestowed posthumously on 17 December 1946. The citation was published in the London Gazette and read: The croix de guerre avec étoile de bronze was awarded by the French government in 1947 and the Médaille de la Résistance in 1973. As one of the SOE agents who died for the liberation of France, Lieutenant Violette Szabo, FANY, is listed on the Valençay SOE Memorial. Both Violette and Étienne Szabo were awarded the French Croix de Guerre for their bravery in the field. On 28 January 1947 their four-year-old daughter Tania was presented with Violette's George Cross (gazetted on 17 December 1946) from King George VI on behalf of her late mother. Violette and Étienne Szabo are believed to be the most decorated married couple of the Second World War. On 22 July 2015, Violette Szabo's medals and numerous associated items were sold at auction, realising £260,000 (£312,000 including buyer's premium). The purchaser was Lord Ashcroft, who placed the George Cross on permanent display at the Imperial War Museum from 7 October 2015. Museums and memorials Szabo has no known grave. Her official point of commemoration is the Commonwealth War Graves Commission Brookwood 1939–1945 Memorial to the Missing in Brookwood Military Cemetery, Surrey. She is named on panel 26. column 3. The Violette Szabo GC Museum is housed in the cottage in Wormelow Tump, Herefordshire, that Violette's English cousins formerly owned, and that Violette would visit before the war to enjoy walks in the surrounding hills. She also stayed at the farm while she was recuperating from her ankle injury and between her two missions to France. Tania Szabo attended the museum's opening in 2000, as did Virginia McKenna, Leo Marks and members of SOE. The Jersey War Tunnels have a permanent exhibition room dedicated to Szabo. The Royal College of Music offers an annual award called the Violette Szabo GC Memorial
