He continued to live in the squalid ghetto until 1944, when the ghetto was liquidated and the Nazis transferred the inhabitants on overcrowded cattle trucks to Auschwitz-Birkenau. Many of the occupants died of dehydration on the journey. He recalled the conditions in the cattle trucks: "They opened those shutters and they started to take people in. When they finished, they couldn't close it, it was so many people. If anybody sat down, other people were standing on them or sitting on them, and they were dying." After several days of travelling in the cattle trucks, Shipper noted that there was more room to sit down. He explained, "Every morning they used to open those shutters and take out dead bodies of people that died, children, grown ups, from starvation, from disease and from suffocation."
