On July 8-10, 1941, mass murder operations were carried out by the Teilkommando 2 of Einsatzkommando A headed by Erhard Grauel, probably with the assistance of the Arajs Commando. Each day, at least 100 Jews were shot. The Jewish men snatched from the streets and their houses and Jewish prisoners from the Women’s Prison were brought to the site by truck in groups of twenty. They were forced to enter the pit – measuring four by fifteen meters – in groups of ten, where they were shot with bolt-action rifles from the edge of the embankment. At first, the marksmen were told to divide the Jews between them, one aiming at the head, the other at the heart. Later, the order was for both gunmen to aim at the head. After a round of killings, German officers armed with machine guns entered the pit to examine the victims, and if any signs of life were found, they delivered “insurance” shots.
