The Los Angeles Museum of the Holocaust presented the U.S. premiere of “Holocaust by Bullets,” an exhibit featuring ten years of field investigations in the former Soviet Union by Yahad-In Unum.

The exhibit will run until March 15.

Yahad-In Unum, founded by French Catholic priest Father Patrick Desbois, presented research on the crimes committed by the Nazi killing units known as the Einsatzgruppen, who went from village to village in the occupied Soviet Union and rounded up Jews, Gypsies and Soviet Commissars and murdered them.

Known as the “Holocaust by Bullets,” the systematic killing of all Jews started before the creation of concentration camps and continued from 1942 to 1944 until WWII’s end.

The exhibit gives viewers a chance to learn about this lesser-known side of the Holocaust through eyewitness testimonies, photographs and maps.

The exhibit presents Yahad’s identification of five steps of the crime that took place almost systematically for every mass killing throughout Eastern Europe leading up to the executions — the arrest, the road, the undressing, the shooting, and after the executions, the looting.

Los Angeles resident Dr. Steven Teitelbaum was inspired by a lecture given by Father Desbois to research and discover the tragic fate of his Polish great-grandparents during the Holocaust.

With the help of a Yahad researcher, Teitelbaum and his family journeyed to his great-grandparents’ ancestral town of Wielopole, visited their old home, interviewed witnesses, and prayed at the site of the executions.

The museum will display items collected by the Teitelbaums and Yahad-In Unum, including photographs, art, and eyewitness testimony from Wielopole residents.

“Unfortunately, this form of genocide, ‘Holocaust by Bullets,’ is the model for mass killings today,” said Marco Gonzalez, director of Yahad-In Unum in Paris. “Thus, the lessons to be learned are practical, and the details need to be exposed for all to see and understand.”

The exhibit is currently being shown until March 15 at the Los Angeles Museum of the Holocaust in Pan Pacific Park, located at 100 S. The Grove Drive.

The museum is opened Monday through Thursday, 10 a.m. to 5 p.m., Fridays, 10 a.m. to 2 p.m. and Saturday and Sunday, 10 a.m. to 5 p.m. Admission is free.
