In addition, several tragedies continued to strike him. In 1942 his wife Elisabet died and in 1943 his daughter Raya, born of a Jewish mother, was deported to the Gaggenau internment camp by the Nazis who occupied Alsace. Debora Logak, the mother of her children living in Montrouge near Paris, was arrested in July 1942 in the sinister French police raid of the Vélodrome d'Hiver. She was held at Drancy internment camp and was believed to have been summarily killed at the Auschwitz internment camp. Having heard that the Third Reich supported artists, Fiebig sent a pension request to Goebbels who could not care less about the painter's works. Although German by birth, he was not well accepted by the Nazi administration, especially as a native of Courland. He was almost forced to display his work during the military occupation of France by Germany in exchange for vague promises of pension that would never materialise. His daughter Raya was miraculously spared after a short Nazi arrest. In spite of multiple requests, the French citizenship would never be granted to him. Hurt by a difficult life during both world wars and personal dramas, he became almost blind from 1946 and could no longer paint or work. After the war, he was sent in 1948 to the Schweisguth barracks in Sélestat set up by the Social Welfare for the needy. Fiebig would remain nostalgic for the landscapes of Courland all his life. He died in poverty in Sélestat on 6 February 1953, leaving behind Raya and a significant but unrecognized art work. His relatives reported that he had been buried in the Protestant cemetery, but the town of Sélestat, whose street is named after him, has no record of his grave in his registers.
