In September 1939, the outbreak of World War II caused Ernst to be interned as an "undesirable foreigner" in Camp des Milles, near Aix-en-Provence, along with fellow surrealist, Hans Bellmer, who had recently emigrated to Paris. He had been living with his lover and fellow surrealist painter, Leonora Carrington who, not knowing whether he would return, saw no option but to sell their house to repay their debts and leave for Spain. Thanks to the intercession of Paul Éluard and other friends, including the journalist Varian Fry, he was released a few weeks later. Soon after the German occupation of France, he was arrested again, this time by the Gestapo but managed to escape and flee to America with the help of Peggy Guggenheim and Fry. Ernst and Peggy Guggenheim arrived in the United States in 1941 and were married at the end of the year. Along with other artists and friends (Marcel Duchamp and Marc Chagall) who had fled from the war and lived in New York City, Ernst helped inspire the development of Abstract expressionism.
