Soon after the wedding the young couple and the whole Margolius family were deported to the ghetto in Lodz. After spending a couple of years there, they were all taken to Oswiecim concentration camp. There the family was parted. Heda was lucky enough to be taken to a labour camp after a few months and was finally made to join the Death March. She managed to escape the guards and thus saved her life.
