Gaeill under Kettil "The Fair" in the Munster territory of Arad Tíre in northern Tipperary. In 858 Máel Sechnaill led a large muster of the men of Ireland into Munster to exact hostages. This time Cerball was his enemy as well as the Leinstermen had complained to the high king of him. The forces of Cerball and Máel Gualae had been stationed at Belach Gabrán in southern Osraige, possibly at Goresbridge on the River Barrow, to oppose the High King's army, but this took an unexpected route and their forces were divided. The High King inflicted a shattering defeat on the forces of Máel Gualae at the Battle of Carn Lugdoch (near modern Waterford) and the King of the Déisi, Máel Crón mac Muiredaig, was slain. The High King remained at Emly for a month raiding all of Munster as far as the sea in Desmond. He took hostages from all the lands of Munster. Many of the Norse-Gaels were slain by the High King's army. The defeat of the Munstermen led Cerball to also submit and give hostages to the high king. The next year however in 859 Cerball again defied Máel Sechnaill and with his Danish allies led an expedition into Mide. This led to a royal conference at Ráith Aeda Meic Bric (modern Rahugh, County Westmeath) with the High King, the kingdom of Cerball was made directly subject to the high king and separated from Munster. Máel Gualae accepted this transfer of authority. That same year Máel Gualae was captured by the Norsemen who stoned him to death His son Dub Lachtna mac Máele Gualae (died 895) was also a King of Munster.
