Explain what happened during the wedding ceremony

Rabbi Boruch, Shmuel, and another man whom Hannah does not know approach the Nazi colonel. A tense conversation ensues but Hannah is not close enough to hear it. When it is over, Reb Boruch announces that the soldiers are there to relocate all Jews to other villages for the duration of the war. They are all to board the trucks and be resettled immediately. Hannah reiterates that they cannot go and that if they do they will be put to death. Her concerns are quickly dismissed by the adults; Rachel reminds them that Chaya had told them about a story called Hansel and Gretel and that she is mixing up the witch's oven and the oven she believes the Nazis will put them in. Hannah sees that no one will believe her story.
