The decision to rise up and fight against the Nazis was made after the great expulsion from the Ghetto, when the Jews in the ghetto reached the conclusion that the fate of all would be death. Only a few tens of thousands of Jews remained in the Ghetto. Some hid in hiding places and decided to fight the Nazis.
The underground soldiers waged a courageous and hopeless war, almost without weapons, against the Nazi army, which was full of well-equipped soldiers. On May 8, 1943, after the great fires that the Nazis had started in the ghetto and the destruction of the other rebel bases, members of the underground were discovered in a bunker that was here. When it became apparent that they had lost their chance to survive, the bunker being surrounded by soldiers (many of the rebels had been poisoned and died by German gas bombs), the rebels of the Jewish Fighting Organization put an end to their lives in the bunker on Mila Street. Only remnants of the bunker remained, and after the liberation of Warsaw from the time of the Nazis, a memorial was erected here.
Many young people in the Ghetto decided to preserve their dignity and die in the struggle and resistance of the Nazis and not in submission to them. The Nazis, who failed to overcome the rebels and capture them, decided to burn house after house in the Ghetto, until the rebels were subdued. The fires spread throughout the ghetto, and when the large area made it difficult to continue the fighting in the bunkers where the fighters were hiding, they began to go out and fight outside their hiding places and were killed or fell into the hands of the Nazis.
In the basement of the building on the corner of 18 Mila Street was where the main bunker of the rebels was located. Here was the headquarters of the Jewish resistance movement and it was sheltering more than 100 people. When the hiding place was discovered by the Germans, they began to throw in lethal gas bombs, most of the rebels in the bunker, commanded by Mordechai Anielewicz, decided to end their lives, just as the Masada fighters had done about 2,000 years before, in order not to fall into the hands of the Romans.
