Taken from John Francis Gilbert’s A Contemporary History of Ireland, from 1641 to 1652, published 1879. The letter has been translated from its original Latin.
Most Reverend Father,
After various ways, partly in vain, by which there might seem a hope of helping our afflicted country, and after which a longer delay than I would otherwise have desired, I have now resolved not to dwell on these any longer; nor to withdraw my aid to help our country. Whence I resolved to commit myself to the perils of land and sea, in order that my country might not be seen wanting by my presence. I am now attached to a ship with some of the nobles of my race. I bid farewell to your Fatherhood, and thank you very much for your zeal for your country and your affection for me. I did not intend to ask your Reverence much that, in his zeal for his country, he should continue his business with His Holiness, lest I should see that your zeal should be called into question by many evidences, all the letters from England, France, Holland, and even Ireland itself, cry out that every day the Catholics should succeed, and if it were not for the scarcity of gunpowder and the machinery of war, they would have already had the whole kingdom under their control. Oh, if only His Holiness knew how deadly this powder would be to the heretics and their supporters! It is unmistakable that he would have wished to provide a remedy for his failure at an early date. But we leave this to the zeal and prudence of your Fatherhood; and with all the devotion of our souls we humbly commend ourselves and the state of our afflicted country to you and the father of our subjects by sacrifices and prayers.
From Brussels. June 7, 1642.
Humble and obedient to your Fatherhood, ready for all obedience.
Don Eugene O’Neill.
Among the first things to be recommended was the request of your Fatherhood to deign to extend to His Holiness the following letters in which I request a blessing for me and for others who are fighting for the faith.
