Isak Kamchi was born in Bitola, Macedonia. During WW II Isak led a partisan unit operating in Croatia. He established a safehouse at his parent's home in Zagreb. His mother ran the safehouse, cooking for the men and nursing them back to health. When the Germans discovered the safehouse, they offered Isak protection in exchange for his surrender. However, when he did surrender, he was arrested and later killed. He may have been publicly hanged.
