151 The Katyn Forest - One Minute History

Before World War Two, the 3rd Reich and the Soviet Union sign a secret nonaggression pact. The Nazis invade Poland from the west, while the Red Army attacks from the east. Many Poles are captured and sent to concentration camps. Stalin orders the execution of 22,000 Polish citizens, which is later blamed on the Nazis.
