In his painting In the Camp (Prison Camp), Nussbaum portrays not only his own individual experiences, but also describes the situation of emigrants in general. As a Jew, the painter was forced to flee in the face of National Socialism. After the attack of the German armed forces on Belgium, the German Felix Nussbaum was branded as an "enemy foreigner" and was deported to unoccupied France. Painting was for Nussbaum a means of fighting for survival and exorcising to horror which he experienced. In 1944, he was sent to his death on the last train which left Belgium for Auschwitz.
