Who does Hannah/Chaya say is REALLY waiting for them in front of the synagogue?

Hannah (Chaya) says the men waiting for them in front of the synagogue aren't wedding guests..... they're Nazis.

"The men down there," she cried out desperately, "they're not wedding guests. They're Nazis. Nazis! Do you understand? They kill people. They killed—kill— will kill Jews. Hundreds of them. Thousands of them. Six million of them! I know. Don't ask me how I know, I just do. We have to turn the wagons around. We have to run!"
