All the Jews had to get a yellow star know as, David's star. Whenever they went anywhere they had to were a coat or jackets and put this star on there cloths so that people would know that they were Jews.
Jews started being captured and sent away so many off them went into hiding, but it was hard because you had to find a person who wasn't a Jew and trust them with you safety.
As Jews were being captured and found and taken out of there hiding places, they were sent to different camps, labor camps and death camps. They would take many Jews put them in a big room, turn off the lights, and gas them with a highly deadly chemical and kill them.
