"There were people who decided to stay behind," Jaros said. "Some had sick or elderly relatives and they stayed to care for them. If my grandmother had not died we would have stayed. Others were afraid and others didn't believe the stories of the executions. All of those who stayed behind were executed."
Jaros' parents decided to join with the partisans and fight the Nazis. To ensure the safety of their son and niece they asked a local farmer to take in the children and pretend they were their own. Jaros was forced to pose as a girl, wearing dresses. He tied a kerchief around his head to hide his short hair until it grew long.
The Jews, at the urging of their friend the priest, learned to pretend they were Catholic. Jaros carried a Rosary and learned the prayers. The Rosary came in handy.
One day, a German soldier came around looking for "Jews, food, eggs and partisans."
"I whipped a Rosary out of my pocket and started saying the Rosary in Polish," Jaros said. "That was one of the scariest moments."
In 1943 Jaros' parents returned and took the children into the woods to live with the partisans. They stayed there two years until the war ended, foraging for food and medicine while surviving harsh Polish winters.
Jaros asked students if they had seen the movie "Defiance." The 2008 movie tells the story of the Bielski brothers, who led a band of Jews into the Polish woods to avoid the Nazis. They are credited with saving thousands of Jewish lives.
"That's my story, our story," Jaros said of the movie. "That's the way we lived. It's 98 percent true. It actually happened. When the Germans got near we would hide in the swamps. It was a difficult life, but we survived."
