John H. Haaren, Famous Men of the Middle Ages… (1904)
“ For the first eight years of his reign there was perfect peace in his kingdom, except in the counties of Kent and Essex, where pirates from the North Sea made occasional attacks.These pirates were mostly Norwegians, whose leader was a barbarian named Kerdric. They would come sweeping down upon the Kentish coast in many ships, make a landing where there were no soldiers, and fall upon the towns and plunder them. Then, as swiftly and suddenly as they had come, they would sail away homeward, before they could be captured. ”
