1173 - 1176 AD
1173 AD Strongbow 11 / Richard de Clare the Cambro - Norman Baron leader, reasserted his hold over Southern Leinster and also led an attack on his brother - in - law in the other part of Mogha's Half, the Munster Province, the kingdom of 110.Donnell Mor O Brian the Heberian Dal gCais 47th King of Cashel / Munster, which was successful, and the previously self - centered 110.Donnell Mor O Brian was now forced to combine with his previous adversary Mac Gilla Patrick (Fitz Patrick) the Heremonian Ui Laoghaire Ui Connla King of Ossory / Co. Kilkenny situated nearby in the south - west of Southern Leinster whose people he had previously slaughtered in battle while continuing to push his own personal agenda. It was now their intention as an Irish combined force to destroy Strongbow 11's fortress and any of the other Anglo - Norman settlements within their territories, and also many of the other Irish Septs who had previously co - operated with the Norman English also began to resist their continuing greedy grab for more and more of their Sept's territories.
Raymond Le Gros Fitz Gerald, the Cambro - Norman Marcher Baron, besieged and burnt the Viking settlement of Lismore in Co. Waterford in the south - east of the Munster Province to the ground, while Robert Fitz Stephen the other leading Anglo - Norman Baron, who was further down along the coast in Southern Leinster had already constructed the first Norman castle at Ferry Carrig in Co. Wexford in the south - east of Southern Leinster against the Vikings and their Irish allies there and despite this there was now new hope in the air for the Irish. Although the main Viking settlement of Dublin in Southern Leinster and most of the Leinster Province overall was now ruled over by the English King Henry 11's Anglo - Norman Barons the far - west and the north of Ireland was still remaining strong as Celtic Gaelic held territories.
1174 AD The Mac Gilla Phadraic (Fitz Patricks) from the Heremonian Ui Laoghaire Ui Connla aristocratic warrior Sept who had their territory in the south - western kingdom of Ossory / Co. Kilkenny in Southern Leinster was composed of 12 Cantreds, Aghaboe in the north, Callan in the mid - west, Erley below there and in the mid - west, Galmoy in the north - west below Aghaboe, Iverk in the south and to the east below Knocktopher and Ogenty, Kells in Central Ossory to the east of Erley were it was surrounded by Knocktopher and Ogenty to the east. Kilkenny was in the centre of the north - east below Odogh and to the west of Oskelan and above Shillelogher, while Knocktopher was in the south above Iverk with Ogenty to the north - east and Kells to the west, Odogh was in the north - east to the east of Galmoy and situated below Aghaboe and to the north - east of Kilkenny and Oskelan, Ogenty was in the south - west below Oskelan and above Knocktopher and Iverk, Oskelan was in the Central - east with Odagh above and Kilkenny to the west and to the north of Ogenty, while Shillelogher was in the Central West below Galmoy and to the west of Kilkenny and to the north of Callan, Erley, Kells and Knocktopher. (All of these Cantreds were originally based on the territories of the individual Irish Tuaths / Family regions of the various Gaelic Septs there in the kingdom of Ossory. These territories in Southern Leinster because of their proximity to the English Pale surrounding Dublin, and the eastern coastal towns of Waterford in the Munster Province, Wicklow and Wexford in Southern Leinster would be taken over by the incessant advancing Anglo - Normans by murder, mayhem, exile, confiscation and total devastation of their crops and the Irish populations who were still surviving in them.
Strongbow 11 / Richard de Clare the Cambro - Norman Baron who was the Galls / foreign leader in Southern Leinster now began a siege also of Thurles in Co. Tipperary on the River Suir in the north - east of the Munster Province, adjacent to Ossory / Co. Kilkenny, which was another part of the territory of 110.Donnell Mor O Brian the Heberian Dal gCais Ui mBriain King of Northern Munster / Thomond who was the 47th King of Cashel / Munster, who on this occasion was able to defeat his allied forces that also included the Ostermen / Vikings from out of Dublin itself, and drive them back to their settlement in Waterford in Co. Waterford on the south - east coast of Munster.

1175 AD
Despite the combined Irish Septs
resistance now to the Galls / foreigners advances,
October: Raymond Le Gros Fitz Gerald the Cambro - Norman Baron, was to now lay siege again also to the territory of 110.Donnell Mor O Brian the Heberian Dal gCais Ui mBriain 47th King of Cashel / Munster, and as a result he re - gained control over the settlement at Limerick in Co. Limerick in the mid - north - west of the Munster Province and put in his own foreign military forces with guides previously supplied under different circumstances by 116.Donnell Mac Gilla Patraic (Fitz Patrick) the previous King of Ossory / Co. Kilkenny. (On this occasion he had been joined by *115.Rory O Connor who had him do it, to try and curtail the ongoing individual ambition of 110.Donnell Mor O Brian).
Henry 11 the Plantagenet Norman King of England and *115.Rory O Connor the 157th King of Ireland had made a new agreement, known as the Treaty of Windsor where Henry 11 recognized *115.Rory O Connor as a lesser King under his overlordship, and he would now have to pay Henry 11 a tribute of 1 in 10 of the beast's hides, that were slain, from all of the Irish Chiefs from all Irish Septs, who had still retained their territories in Meath / Midhe in both Northern and Southern Leinster. (Henry 11 was also to further gain control over other parts of the east coast of the Munster Province, between Waterford and Dungarvan). It was further proposed that from now on the Irish Septs were to be ruled over by *115.Rory O Connor and the Heremonian Dal Cuinn Ui Briuin Ai Siol Muireadhaigh Ui Conchobair O Connors, and the Anglo - Norman English by Henry 11 as their actual overall overlords in Ireland, with the Catholic Archbishop of Tuam, the Abbot of Clonfert, and Laurence / Lorcan O Toole the Archbishop of Dublin initially arranging the agreement in the interests of trying once again to bring about the originally proposed peace for *115.Rory O Connor.
April: Strongbow 11 / Richard de Clare the leader of the Cambro - Norman Marcher Barons, died, leaving a minor as his heir, and his body was interred in the church in Dublin that he had previously constructed where Christchurch Cathedral now stands, together there with his previous 15 year old son, who he had personally cut in half for perceived cowardice in a rage of anger. 110.Donnell Mor O Brian and Raymond Le Gros Fitz Gerald the Cambro - Norman Baron, went to Limerick City where they were informed of his demise and Raymond Le Gros Fitz Gerald then went onto Dublin leaving 110.Donnell Mor O Brian in charge of the settlement there. With Strongbow 11 gone off the scene 110.Donnell Mor O Brian seeing this as a great opportunity to once again begin to drive the Anglo - Norman English out of Dublin and Ireland altogether he killed most of Henry 11’s military garrison there in Limerick and set it alight, so that it would not be a stronghold in the future for the Galls / foreigners. With Strongbow 11 the perceived overall leader of the Anglo - Norman Barons gone, 112.Murtogh / Muirchertach Mac Loughlin / Mac Lochlainn the Dal Cuinn "northern" Ui Niaill Cenel nEogain 58th King of Aileach in the north of the Ulster Province, who was the son of *111.Murtogh Mor Mac Loughlin the previous 174th King of Ireland, headed south with his "northern" Ui Niaill warriors to besiege the Dal Cuinn "southern" Ui Niaill territory in Meath in the south of Northern Leinster, that was still under the control of Hugh de Lacy the other leading Anglo - Norman Baron in Ireland acting for Henry 11 the English Norman King.
114.Aedh Macaomh Toinleasc - the Lazy Limbed Youth O Niall the Dal Cuinn Cenel nEogain King of Tir Eogain / Co. Tyrone in the Ulster Province now became the overall Cenel nEogain King and heir apparent / Tanaiste of Ireland, who was a son of 113.Murtogh / Muirchertach Magh Line O Niall who had been killed in 1160 AD, who had been a son of 112.Teague / Tadhg an Glinne O Niall who was in turn descended from 103.Niall Glun Dubh - of the Black Knee the previous165th King of Ireland who had been killed by the Vikings in Dublin, and who is the direct male line ancestor of all the O Nialls / O Neills in Ulster.
