Simon was also stationed in Nuremberg, Germany. In the company of his military chaplain Colonel Cate, a priest of the Camillian Fathers who cared for the sick, Simon was able to attend the Nuremberg War Criminal Trials held in Nuremberg’s Palace of Justice. The Four Allied Powers of the U.S.A., England, France, and Russia were represented, and testimony was given in different languages. Simon had seen the rubble and the effects of World War II, but he had also seen the work toward justice and peace.
