Chaplain Kapaun carried this small brass pyx on his person in the POW camp until it was confiscated by his Chinese captors and made into a child's toy. Kapaun always carried the pyx inside the prison camp in case he needed to administer the Holy Communion to the sick and dying. Following his death, Kapaun's fellow prisoners-of-war convinced their captors to return the pyx. Kapaun received the Medal of Honor posthumously for his acts of selfless service in providing aid and comfort to the wounded during the battle of Unsan during the Korean War. The missal would have been used by Fr. Kapaun when he was saying mass.
