When 15-year-old Tillie Pierce laughed when a minister told her that the Lord would reward her for her help at the Weikert Farm field hospital in July of 1863, she quickly apologized. Tillie, a well-brought up young woman, had just helped soldiers who had had arms and legs amputated. She had seen soldiers blown up by artillery in nearby fields. Why would she laugh? High school students work cooperatively to explore our reaction to horror and whether it is appropriate.
