With the outbreak of World War II Ernst, who was German, was arrested by the French authorities for being a "hostile alien". With the intercession of Paul Éluard, and other friends, including the American journalist Varian Fry, he was discharged a few weeks later. Soon after the Nazis invaded France, Ernst was arrested again, this time by the Gestapo, because his art was considered by the Nazis to be "degenerate". He managed to escape and, leaving Carrington behind, fled to the United States with the help of Peggy Guggenheim, who was a sponsor of the arts.
