How does Marchesa make a difference in the lives of the refugee children who arrive at La Foce in the nonfiction book, War in Val D'Orcia, 1943-1944?

At the beginning of the diaries, a group of children arrives at La Foce taking refuge from the bombing and fighting in their home cities. There are glimpses, in the diaries, of the Marchesa's efforts to continue their education, to entertain and distract them, but her first priority is simply to preserve and sustain their lives. Their well being, she seems to imply, is her primary concern.
