Ronan McGreevy of the Irish Times has produced a fascinating documentary about the Irish involvement in World War 1. Today the Irish Times published the segment featuring the Battle of Passchendaele and the Irish involvement therein. Fr Doyle features extensively, and we get a glimpse of the terrain where he worked and was killed. 

Thanks to Ronan for his hard work in keeping the memory of these Irish soldiers alive and for his ongoing interest in Fr Doyle.
