The United Nations International Day of Commemoration in memory of the victims of the Holocaust commemorates the Red Army's liberation of Auschwitz on January 27, 1945.
In the end, it was only the might of the Allied armed forces which ended the Holocaust in conjunction with the determination of Allied political leaders to defeat Nazi Germany and the sacrifices made on the respective home fronts.
The Soviet Union bore a terrible burden in the Second World War – a conflict it helped to ignite with its August 1939 pact with Germany on the eve of the German invasion of Poland. Twenty million Soviet citizens were killed or murdered and its leading cities were largely laid to ruin. The fierce resistance of Soviet armed forces in the immediate weeks after the German invasion – often surrounded and ill-equipped – saved the USSR from disintegration while Stalin and the Soviet leadership regained their equilibrium.
Then came the epochal battles over the next three years invoking Moscow, Leningrad and Stalingrad followed by vast engagements, often armored, over the expanses of European Russia as Soviet armed forces counterattacked across broad fronts to drive the Germans out of the USSR. Meanwhile, the "Holocaust by Bullets" commenced on Russian soil. (See, Desbois, Father Patrick. The Holocaust by Bullets. New York: Palgrave Macmillan, 2008. Print.). The German Einsatzgruppen slaughtered over one million Jews by machine gun and rifle fire along with Russian Orthodox priests, Communist party officials, Russian prisoners of war and others.
The D-day invasion in June, 1944 opened the second front of the western allies and created one side of the giant pincer which closed when American and Soviet troops met at the Elbe in April, 1945. In this ten month period, the Americans, British and Canadians liberated the concentration camps of Dachau, Bergen-Belsen, and Buchenwald among others finding a remnant of Jews, German political prisoners and nationals of other countries and slave laborers from throughout Europe. In the liberation of Auschwitz, Treblinka and Majdanek, the Soviets discovered the gas chambers and crematoria which the Germans had tried to destroy in their retreat from the Russian forces.
In the first part of 1945, the world from media reports began to learn of the Final Solution and the nearly successful destruction of European Jewish and Roma peoples along with homosexuals, German "undesirables" and other "inferior races." As General Dwight Eisenhower declared after visiting Buchenwald:
"I have never felt able to describe my emotional reaction when I first came face to face with indisputable evidence of Nazi brutality and ruthless disregard of every shred of decency...I visited every nook and cranny of the camp because I felt it my duty to be in a position from then on to testify at first hand about these things in case there ever grew up at home the belief or assumption that the stories of Nazi brutality were just propaganda."
The revelations of the Holocaust were seismic for the American Jewish community. To this day, a debate continues about the appropriateness and tenacity of the response of the leadership of the American Jewish community when unofficial word of the Nazi atrocities began to leak out of Europe reaching Britain and the United States in 1942. Preferring quiet engagement with a President and an executive branch considered sympathetic to Jewish concerns against a backdrop of polling levels showing high levels of multi-faceted, ingrained and potentially militant anti-Semitism, leadership more often than not through 1944 acceded to the Roosevelt administration's maxim that an expeditious defeat of Germany was the best way to help Europe's Jews. Anything that went counter to this approach was a hindrance to the war effort – a war derided by German propaganda and American anti-Semites as a "Jewish war." The Roosevelt Administration and American Jewish leadership were sensitive to the provocation and power of this canard in a country where before World War II between one-third and one-half of the public believed the Jews had "too much power in the United States" (Wyman and Medoff, "A Race Against Death: Peter Bergson, America, and the Holocaust," The New York Press, 2002; p. 2).
