Butrimonys massacre.
On 9 September 1941, shortly after the Nazi invasion of the Soviet Union, the Jews of Butrimonys were massacred by Einsatzgruppen and Lithuanian collaborators. Rounded up and marched along a road, they were lined up beside a mass grave and machine-gunned. According to the Jäger Report, 740 Jews were murdered in one day: 67 men, 370 women, and 303 children.
What distinguished Butrimonys from hundreds of similar crimes in the Baltic region was the survival of a detailed record left by a local Jew Khone Boyarski. Hiding with his son, Boyarski described the events in a farewell letter to his relatives abroad. Boyarski was later killed by the Nazis; the letter was discovered by accident by a graduate student in the archives of Yad Vashem.
