 In 860 Máel Sechnaill and Cerball led a large army of men from Munster, Leinster, Connacht and the Southern Uí Néill into the lands of Áed Findliath near Armagh.While the southern forces were encamped there, Áed launched a night attack, killing some of the southern men, but his forces took many casualties and were forced to retreat.In retaliation for this invasion Amlaíb and Áed led raids into Meath in 861 and 862, but they were driven off both times.
