In Elie Weisel's "Night," where are the Jews sent first after the arrival of the German soldiers?

The first place the Jews of the village of Sighet were sent when they were deported was to Birkenau, which was part of the most infamous concentration camp at Auschwitz, in Southern Poland.

The Nazis actually had given two decrees prior to evacuating the Jews from Sighet.  The first time, they arrested all those who were foreign-born, including the teacher, Moshe the Beadle, who returned to tell the Jews that all those whom the Nazis had taken had been exterminated.  The second decree given by the Nazis established Jewish ghettoes within the community, along with a long list of anti-Semitic laws.  Finally, the Nazis packed all the Jews of Sighet onto boxcars, and transported them to Birkenau.
