The most outstanding act of Jewish resistance was during these four weeks when SS and Gestapo units killed a total of 56,065 Jews during the liquidation of the Warsaw Ghetto. The operation was commanded by SS Brigadier-General Stroop, who, in his report to Hitler, wrote "The Jewish Ghetto in Warsaw no longer exists". On March 22, 1947, Stroop was sentenced to death by an American court at Dachau and on September 8, 1951, he was hanged at the scene of his crime in Warsaw.

The Warsaw Ghetto was enclosed by a 10-foot high wall inside of which were herded between 400,000-410,000 Jews. Guards in German uniform and Jewish policemen maintained a rigid check on everyone entering or leaving. Many Jews turned against their own people and worked for the Nazis only to stay alive.

The majority of Jews in the Ghetto hated these collaborators more than they hated the Nazis. Every Jewish child was taught, and this saved the lives of some of them: "if you enter a square from which there are three exits, one guarded by a German SS man, one by an Ukrainian and one by a Jewish policeman, then you should first try to pass the German, then maybe the Ukrainian, but never the Jew".

The Warsaw Uprising cost the German forces 17 dead and 93 wounded.

In 1939 there were some 3,474,000 Jews living in Poland. (359,827 in Warsaw).

After the war, 55,509 registered as survivors, a loss of 98% of Poland's Jews.
