Scotland, after suffering a defeat in an engagement with the White Gentiles. They were, however, consoled by a victory over the men of Alba, in which Constantine, son of Kenneth, was slain, and many others with him. Their success proved beneficial to Ireland, for we are told that a period of "rest to the men of Erinn" ensued. The Danes still held their own in Dublin and at Limerick, occasionally plundered the churches, and now and then had a skirmish with the "men of Erinn;" but for forty years the country was free from the foreign fleets, and, therefore, enjoyed a time of comparative quiet. In the year 913 new fleets arrived. They landed in the harbour of Waterford, where they had a settlement formerly; but though they obtained assistance here, they were defeated by the native Irish, both in Kerry and in Tipperary. Sitric came with another fleet in 915, and settled at Cenn-Fuait.[204] Here he was attacked by the Irish army, but they were repulsed with great slaughter. Two years after they received another disastrous defeat at Cill-Mosanhog, near Rathfarnham. A large cromlech, still in that neighbourhood, probably marks the graves of the heroes slain in that engagement. Twelve kings fell in this battle. Their names are given in the _Wars of the Gaedhil_, and by other authorities, though in some places the number is increased. Nial Glundubh was amongst the slain. He is celebrated in pathetic verse by the bards. Of the battle was said:-- "Fierce and hard was the Wednesday On which hosts were strewn under the fall of shields; It shall be called, till judgment's day, The destructive burning of Ath-cliath." The lamentation of Nial was, moreover, said:-- "Sorrowful this day is sacred Ireland, Without a valiant chief of hostage reign! It is to see the heavens without a sun, To view Magh-Neill[205] without a Nial." "There is no cheerfulness in the happiness of men; There is no peace or joy among the hosts; No fair can be celebrated Since the sorrow of sorrow died."
