Flann died the following year, A.D.914, and was succeeded by the prince who had so ably defended him.

Meanwhile, the Danes were not idle.

Amlaff[203] has signalized his advent by drowning Conchobhar, "heir apparent of Tara;" by slaying all the chieftains of the Deisi at Cluain-Daimh; by killing the son of Clennfaeladh, King of Muscraighe Breoghain; by smothering Machdaighren in a cave, and by the destruction of Caitill Find (Ketill the White) and his whole garrison.

Oisill is the next chief of importance; and he "succeeded in plundering the greatest part of Ireland." It is not recorded how long he was occupied in performing this exploit, but he was eventually slain, and his army cut off, by the men of Erinn.

The deaths of several Danish chieftains occured about this period, and are referred to the vengeance of certain saints, whose shrines they had desecrated.
