Robinson Crusoes of Warsaw

The term Robinson Crusoes of Warsaw, or the "Warsaw Robinsons", refers to Poles (including Jews) who, after the end of the 1944 Warsaw Uprising and the subsequent planned destruction of Warsaw by Nazi Germany, decided to stay and hide in the ruins of the German-occupied city. The period of hiding spanned as long as three and a half months, from the day of the capitulation of the uprising, October 2, 1944, until the entry of the Red Army on January 17, 1945.
