Note 151 — Chapter X · THE FLEETS OF THE NORTHMEN.
Reading edition
Unfortunately some of the facts which we would like to know are missing in the Northern records in regard to the size of the fleet which came to England, with the son of Ragnar Lodbrok; but from what old English chronicles tell us, and from the depredations committed by them, we may assume that their number must have been very great. The same may also be said about the fleets of Svein and Knut.
