Fr Doyle left his training camp and headed to the continent 101 years ago today. Here are his sentiments on this occasion, as captured in a letter written to his father just half an hour before departure.

I set out to face to future with a certain amount of trepidation…Strange to say, I have not the smallest anxiety about the possible dangers of warfare, not so great for me, as for others, but I do dread the horrors of the battlefield which all say no words can picture. Still it is a consolation to know what a comfort the mere presence of a priest is to both officers and men alike. They are one and all going to face their duty with the joy of heart which comes with a clear conscience; many of them had not been to confession for over twenty years.
