A vast number of documents remain to show that Edward I. took great pains about Ireland. Phelim O'Connor, who died in 1265, may be regarded as the last King of Connaught. His son Hugh did indeed assume the title, and, according to the annalists, 'executed his royal depredations on the men of Offaly, where he committed many burnings and killings;' but his kingship does not appear to have been officially recognised, and the De Burgos were the true rulers. The Red Earl was supreme in the northern half of Ireland; but O'Neill was recognised as King of Tyrone, while his claim to be head of all the Irish in Ireland was denied. O'Cahan was also sometimes given the title of king. O'Donnell was treated with less respect, and a price was set upon his head, which appears to have been actually brought to Dublin in 1283. In 1281 Hugh Boy O'Neill, whom the annalists call 'royal heir of all Erin, head of the hospitality and valour of the Gael,' sided with the English against Donnell Oge O'Donnell, who is called 'King of the north, the best Gael for hospitality and dignity; the general guardian of the west of Europe, and the knitting-needle of the arch sovereignty, and the rivetting hammer of every good law, and the top-nut of the Gael in valour.' A battle was fought near Dungannon, and O'Donnell, who had under him the O'Rourkes and MacMahons, and 'nearly the majority of the Irish of Connaught and Ulster,' was defeated and slain. Two years later Hugh Boy was killed by the MacMahons. The story of this contest is a good illustration of the hopeless incapacity of the natives for anything like a national combination. If Edward I. had been able to attend to Ireland personally, it is at least probable that he would have conquered the country as completely as Wales.
