Born in Canada to the children of Irish emigrants, Francis P. Duffy (1871-1932) left a lasting legacy among his parishioners and in the regiment and army in which he served. I have just written an Irish Diary about the famous US army chaplain in the Irish Times newspaper. Read it here.
In 1919, Fr Duffy wrote a book about his experience of the War. It was called Father Duffy's Story: A Tale of Humor and Heroism, Of Life and Death with the Fighting Sixty-Ninth. You can read it here on the Project Gutenberg website. If you would like to learn more about Fr Duffy and his life and times, you can have a look at these websites:
