And where were those Jews from?
Not Germany. Not Poland. Not Hungary or France. They were Jews who had been living in Spain and allied-occupied portions of Southern Italy, where there was no Holocaust, and where their chances of being exterminated were effectively nil. It was easy to save Jews who did not need saving.
Saving those who did need saving was a bit tougher...
Actually, they were mostly from Nazi occupied countries. They had escaped, I think first to Yugoslavia. When they first landed in Italy, they were just in time for the town they landed in to be shelled, then searched by the Nazis.
