One year later, the Battle of Castledermot- the invasion of Ireland by the Bruces. In 1318, the invasion of Fochart Ireland by the Bruces at Dunalk.
The battle of 'Dysert O'Dea' was in 1318. When Richard de Clare heard of the devastating defeat of his allies at Corcomruadh, he decided to attack O'Dea at Dysert and so cut off the strong arm of the combined Gaelic opposition. His troops arrived at Ruan on the morning of May 10, 1318, and were divided into three columns. The first column, headed by his son, marched northwards to Tullach O'Dea to cut off help which might arrive from O'Connor of Ennistymon. The second division marched southwards towards Magowna to intercept any support from that side. The third division, under his own command, marched westwards towards Dysert O'Dea, the home of Conor O'Dea of Clan Ó Déaghaidh who held back the Anglo-Norman advance. Conor O'Dea's men at the ford, rushed across with some English knights and was immediately surrounded by the O'Deas. Feilim O'Connor's troops charged down the hill of Scamhall (Scool) and cut a path through the English to join O'Dea in the fray. De Clare's son arrived on the scene and was cut down and killed by Feilim O'Connor. About this time news reach Muircheartach O'Brien, who was encamped about 10 miles east of Dysert O'Dea. Soon Lochlann O'Hehir and the MacNamaras joined the fight. Those of the race of Brian Rua who made it across the Shannon were banished forever from the Kingdom of Thomond. Later the Irish arrived at Bunratty to find the castle ablaze and de Clare's wife and household fled to England.
In 1395, Richard II came to Ireland bringing with him a large army to subdue the Irish chiefs and met him at Magh Adhair on March 14th, 1395, where each chief submitted to him on behalf of his people. Ruaidhri O'Dea represented his clansmen of Cineal Fearmaic, Dalcassian in origin. After Richard II went back to England, the Irish returned to the ways and laws of their ancestors. The Dysert O'Dea towerhouse was built between 1470 and 1480 by Diarmaid O'Dea.
