On this day in 1941, the Nazi Army took over Kyiv, Ukraine, and the SS prepared to kill all of the Jews in the area. After the Nazi invasion, two explosions destroyed the German headquarters. The Germans used it as a reason to immediately blame, and subsequently kill, the remaining Jews. Almost 100,000 Jews fled Kyiv as the Germans were approaching, leaving behind mostly women, children, the elderly, and the weak. Throughout 1941 and 1942, many massacres occurred, killing about two million people, at least 1.5 million of whom were Jewish. The individual shooting of the victims affected the Nazi soldiers' psyche, while the Nazi leadership felt this method to be too slow and costly. Thus, the Final Solution was confirmed at the Wannsee Conference in January of 1942.On this day, the SS troops marched over 34,000 Jews to the Babi Yar ravine, right outside of Kyiv, and executed them. It is known as the third-largest mass killing in one location by German forces, with an estimated 100,000 people killed and only 29 survivors. The same ravine was used over the next two years as a mass grave for other Jews and Soviet officials.At the end of the War, when the Soviet Army was closing in on the Germans near Kyiv, the Nazis tried to get rid of the evidence of Babi Yar by returning to the site and burning the bodies. But they were not successful in this, and together with the other evidence that remained and the eyewitness accounts, there is an awareness of the atrocities that occurred there. In January 1946, there was a trial against 15 members of the German Police for crimes that were committed at Babi Yar.
