O'Duibhne down to the middle of the seventeenth century, for in the national manuscripts of Scotland there is a very fine Gaelic poem on the death of a Campbell, who is styled "O'Duibhne" in the Gaelic. Translations that have been recently made from Gaelic manuscripts of high authority have thrown considerable light on Finn, and the events of his epoch. We are told in the tract called the "Boramha," or "Tribute," to which reference has been already made, that when Bresal, a king of Leinster, in the third century, was given his choice to pay the tribute or fight the rest of Ireland, he asked help from Finn. A person called Molling was sent to ask Finn to help the men of Leinster. Molling told Finn that he should not come with a small army to fight the chief king, who had the national army with him. The number of men that Finn had, was, we are told in the "Boramha," fifteen hundred chiefs, each having thirty men under him, making the total number of men that Finn brought to help Leinster forty-five thousand, a very large army in those days. They joined the Leinster men, inflicted a crushing defeat on the forces of the chief king, so that the tribute was not paid for many years after. Nine thousand of the "men of Ireland," as the "Book of Leinster" almost invariably calls the national forces, were slain in the battle. The militia of which Finn was the Commander-in-Chief, and of which his father and grandfather had also been commanders, are the heroes of hundreds of Ossianic tales and poems. It would appear that they numbered twenty-one thousand men on a peace footing, but could raise their numbers to double that amount in time of need. They became so extortionate and arrogant in the long run, that the chief king, Cairbre, and it would seem all the provincial rulers except the King of Leinster, determined to crush them. So a great battle was fought at Garristown in the County Dublin in the year 290 or 296, and the militia of Finn was totally destroyed. It would seem that neither Knock Aillinn nor the hill of Allen has been since then inhabited. It may not be out of place to state here that students of Gaelic are often puzzled on seeing the name of Finn spelt _Fionn_. It seems certain that _Finn_ is the proper orthography. The name is invariably so spelt in all cases in the "Book of Leinster," one of the most correct of all the great Gaelic books; but the editor of "Silva Gadelica" makes it _Fionn_ in all cases except in the genitive. It is difficult to understand why, when copying from a manuscript of such high authority as the "Book of Leinster," he did not follow its orthography. In the northern half of Ireland the name is pronounced according to its correct orthography, but in the south of Ireland it is pronounced as if written _Fyun_.
