 Between the end of the Warsaw Ghetto Uprising ( May 1943 ) and beginning of 1944 , there were between 10 @,@ 000 and 20 @,@ 000 Jews hiding in the Ghetto ruins . The number of Robinsons after the Warsaw Uprising has been estimated at between several hundred and two thousand , spread across all the suburbs of Warsaw . Another source gives the number as between 400 and 1 @,@ 000 . Most of those hiding were Jewish , including some who had been in hiding since the fall of the ghetto uprising , though a significant number were non @-@ Jewish Poles . Unlike Szpilman , whose case was somewhat unrepresentative , most of those in hiding remained in medium @-@ sized to large groups , often of mixed ethnicities . The majority of the Robinsons were men .
