In 1940, De Vries moved back to Drenthe. During the Second World War, De Vries was involved in the Dutch Resistance. De Vries also held contacts with Johannes Post, of whom he later also wrote a biography. In 1945, De Vries was arrested by the Sicherheitsdienst, but was released because one of the Nazi officers loved his novel "Hilde".
