Clovis and company wintered in North Umbria into 869. In the summer he travelled with Ivar to Ireland. The vikings planned to raid the Irish country, but the sons of Erin had united and their army kept the norsemen bottled up in their port of Dublin.
Ivar devised a plan to fracture the Irish alliance. He sent Clovis to the north to attack Irish holds to draw off their forces.
The irish sorcerers had also summoned some foul magic air from the village well and it had put one of the camp folloers into an eternal sleep before Clovis discovered it.
The company abandoned the village beore the trap was sprung. They returned to Dublin on their ships, giving the hostages to Ivar.
