Mac William de Burgo accompanied by a great army of foreigners and Gaedhil invaded Desmumu, and Cormac Mac Carthaigh was slain by them after a victory of prowess and valour. For he himself unaided, slew Gerald Roche,76 a great and noble knight, and another good squire, and no others of the Desmumu fell save he, although many of the (enemy) army were slain. Nevertheless, some of the Clann Charthaigh gave hostages to Mac William and he left the country.
The account in the
Annals of Loch Cé differs slightly from the above:
A.D. 1262. A hosting by Mac William Burk and the foreigners of Erin to Desmumha to attack Mac Carthaigh, until they reached the Mangartach of Loch Léin, where Gerald Roche was slain by Mac Carthaigh; and it was said that he was the third best baron in Ireland. And this was the joy with sorrow to Desmumha, for the son of Domhnall Got Mac Carthaigh, i.e. Cormac, son of Domhnall, was slain on that same day; and the foreigners and the Gaedhil suffered great losses on that day around the Mangartach.77
From these accounts it would seem that while Cormac failed to match Finghin's exploits, the Normans gained little advantage either. It is significant that references to attacks on Desmond scarcely occur at all after 1262.78 It is to this period that Hanmer's often-quoted account refers:79
The Carties plaied the Divells in Desmond, where they burned, spoiled, preyed, and slue many an innocent; they became so strong, and prevailed so mightily that for the space (so it is reported) of twelve yeeres the Desmonds durst not but plow in ground in his owne country.
Attempts at subduing the Mac Carthys were of little avail. James de Audley (justiciar from 1270 to 1272) led an expedition against Irish rebels in Desmond86; no results were announced. The Annals of Innisfallen (A.D. 1271) tell us: "A hosting by the foreigners of Ireland into Desmumu to Dún na mBarc, and they turned back from there without doing any further damage."
In 1280 the Mac Carthys of Carbery (then headed by Domhnall óg son of Domhnall Mael) made peace with the main branch of the family, whose king was Domhnall Ruadh mac Carthy.87 They then united to drive out the foreigner. Killorglin was burned and its castle razed. 'And great forays were made there and people slain.' The Normans then evacuated Dunloe, which was promptly burned
Still Domhnall óg (Cairbreach) remained a thorn in the side of the Norman interests. In 1295 he was plundering as far east as Kinalea, having already burned Macloneigh.90 Two years later, he slew John de Courcy, probably to avenge his uncle's death at the hands of Miles de Courcy. When Hubert de Courcy tried to bring Domhnall to justice, the sheriff reported that Domhnall would not submit to justice, and a few months later, that he 'was among the Irish in waste land where no sergeant or bailiff of the king dared to go to attack him.'
