Carole Hope is an expert on Fr Doyle’s military career and is the author of the superb biography Worshipper and Worshipped.

She recently gave a lecture in Dublin on Fr Doyle’s experience in this gas attack 100 years ago this week. Below you will find two videos on this lecture courtesy of Ronan McGreevy, a journalist in the Irish Times whose book Wherever the Firing Line Extends: An Irish Journey Along the Western Front will be published shortly.
