The Umschlagplatz Monument in Warsaw, Poland, where more than 300,000 Jews were transported from the Warsaw Ghetto to Nazi death camps.

The uprising — the largest single Jewish revolt of World War II — was launched 78 years ago when Nazi Germans tried to transport the population of the Warsaw Ghetto to the Majdanek and Treblinka death camps.
