You can read about the Lithuanian Jews in this news story:
The following quote is from the news article:
“Holocaust Escape Tunnel,” a “Nova” production to be shown April 19, sheds new light on the attempt by 80 imprisoned men and women — mostly Lithuanian Jews — to make a break for freedom in the face of Nazi bullets. The show documents the application of scientific methods to verify what would otherwise be a nearly unbelievable story.
The documentary is set in and around Vilna, the Yiddish and Hebrew designation for Vilnius, the capital of Lithuania. At its peak, before World War II and the Holocaust, the city boasted a Jewish population of some 77,000, had 105 synagogues, the largest Jewish library in the world and six daily Jewish newspapers.
I have written about the Lithuanian Jews several times on these blog posts:
Unfortunately, many people do not believe the story of the Lithuanian Jews. I do not believe it either.
