I’ve read a book about Fr. Kapaun. I cannot immediately recall the title, but I havn’t forgotten how inspiring it was. There is no doubt in my mind that Fr. Kapaun is a saint, and I’d love to see it become official.
“A Shepherd in Combat Boots,” by William Maher. Excellent book, not only about Fr. Kapaun, but about the circumstances of the Korean War. Supplements the recent comprehensive history of the Korean War (The Coldest Winter) quite effectively.
