310 discharged bullet casings, with the contemporary archeological bag used to transport them, recovered in 2005 by Yahad-In Unum at a mass execution site in Khvativ, a small village in the Lvivska province of Ukraine. A casing contains propellant and primer, and holds the bullet in place. Several casings have a headstamp marking the German manufacturer, location, year, batch, and material. In September 1939, following Germany's invasion of Poland, the Lvivska province was occupied by the Soviet Union pursuant to the terms of the German-Soviet Pact. In late June 1941, Germany launched Operation Barbarossa, a surprise attack on Russia. The military assault was coordinated with killing squads whose goal was the Final Solution, the elimination of all Jews from the conquered territories. With the assistance of trained collaborators and the local populace, the goal was achieved through deportations to killing centers and mass executions throughout the region. The lack of adequate rail transport meant that many villages had killing fields where the Jews were shot and buried in huge ditches, along with the bullets and other evidence. Through interviews with the remaining eyewitnesses, Yahad-In Unum locates and documents these remains of a Holocaust by bullets and offers respectful remembrance for the fallen.
