4. How does Vladek’s friend, Ilzecki save his son during the war? How does Vladek try to save his son Richieu? What happened?

1.) Ilzacki saved his son by sending him to hide with a Polish family until the war was over.

2.) Vladek sends Richieu to live with Uncle Persis, thinking he'll be safer there. When the town of Zawiercie is liquidated, Tosha (Richieu's aunt), poisons herself and the children so they won't be sent to the gas chamber.
