The refugees rescued from German WWII camps were sent to Belgium.
From there they were distributed to either the UK, Canada or Australia
if they didn't want to be repatriated to their country of origin.
If we go by statistics recorded in Auschwitz as a general guide
to expanded camp numbers, the slave laborers consisted
of people from many nations.
Jews were recorded as being 15% of the prison population, totaling some
408000 over the 5 year lifespan of the facility.
I have no idea what gorillion you may be referencing?
