Katyn Commission
The Katyn Commission or the International Katyn Commission was a committee formed in April 1943 under request by Germany to investigate the Katyn massacre of some 22,000 Polish nationals during the Soviet occupation of Eastern Poland, mostly prisoners of war from the September Campaign including Polish Army officers, intelligentsia, civil servants, priests, police officers and numerous other professionals. Their bodies were discovered in a series of large mass graves in the forest near Smolensk in Russia following Operation Barbarossa.
