Fr Doyle wrote the following in his diary on this day in 1916:

I have celebrated Mass in some strange places and under extraordinary conditions but somehow I was more than usually impressed this morning. The men had gathered in what was once a small convent. For with all their faults, their devil-may-care recklessness, they love the Mass and regret when they cannot come. It was a poor miserable place, cold and wet, the only light being two small candles. Yet they knelt there and prayed as only our own Irish poor can pray, with a fervour and faith which would touch the heart of any unbeliever. They are as shy as children, and men of few words; but I know they are grateful when one tries to be kind to them and warmly appreciate all that is done for their soul’s interest.
