Brunon’s schooling consisted of five grades of primary school. He then followed practical training in a tile factory. Because he loved gardening, he went to work on the farm of a German owner. In 1938, he was mobilized for an infantry division of the Pomeranian (Polish) Army that took part in the battles at the Bzura River from September 9 to 19, 1939. On the flight to Warszawa he was captured, escaped and returned home at the end of September where he resumed his old work. Under pressure, many Kashubians registered as German citizens, so that they retained their property and right of residence, but also committed themselves to labor and military service. Unregistered Kashubians and Poles could be expelled at any moment and tens of thousands of them were actually expelled, if they survived a previous internment, such as in the Stutthof concentration camp near Danzig.
