pupils named it Grüber School. By autumn 1939 a new degree of persecution loomed. The Nazi authorities started to deport Jewish Austrians and Gentile Austrians of Jewish descent to occupied Poland. On 13 February 1940 the same fate hit 1,200 Jewish Germans and Gentile Germans of Jewish descent and their Gentile spouses from the Stettin Region, who were deported to Lublin. Grüber learned about it by the Wehrmacht commander of Lublin and then protested to every higher ranking superior up to the then Prussian Minister-President Hermann Göring, who forbade further deportations from Prussia for the moment. The Gestapo warned Grüber never to take the side of the deported again. The deported were not allowed to return. On 22–23 October, 6,500 Jewish Germans and Gentile Germans of Jewish descent from Baden and the Palatinate were deported to Gurs, occupied France. Now Grüber got himself a passport, with the help of Bonhoeffer's brother-in-law Hans von Dohnanyi from the Abwehr, to visit the deported in the Gurs (concentration camp). But before he left the Gestapo arrested Grüber on 19 December and deported him two days later to Sachsenhausen concentration camp, and in 1941 to Dachau concentration camp. Sylten was ordered to shut down the Bureau, which he did until 1 February 1941. On 27 February the Gestapo arrested and deported him by end of May to Dachau concentration camp, where he was murdered in August 1942. Grüber survived and was released from Dachau on 23 June 1943, after he had signed not to help the persecuted any more. The Family school was ordered to close by the end of June 1942. Draeger dived into the underground by the end of 1942, hiding in Berlin and surviving through some undaunted helpers, but was caught later and deported to Auschwitz in August 1944, where she perished. Persons hiding from deportation used to call themselves submarine (). The fate of other collaborators of the Bureau: Paul Heinitz died in peace in February 1942, Günther Heinitz, Werner Hirschwald, Max Honig, Inge Jacobson, Elisabeth Kayser and Richard Kobrak were all deported and murdered in different concentration camps. Since January 1943 Pastor Braune could hide Luise Wolff in the diaconal , so she survived. Among the undaunted helpers in the Evangelical Church of the old-Prussian Union, hiding and feeding the 'submarines', were many women, but also men, such as Bolette Burckhardt, Pastor Theodor Burckhardt, Helene Jacobs, Franz Kaufmann, Pastor
