I walked the walk Janusz Korczak walked with his children, the orphans, from the orphanage to Umschlagplatz.

Here's some info about Korczak.

'Korczak’s orphanage’s turn came on August 6. He and the staff had made up their minds earlier: all of them would go together. And they would go quietly, in an orderly fashion, so as not to frighten the children.
