The Dragon and the Raven oleh G. A. Henty

In this story the author gives an account of the fierce struggle between Saxon and Dane for supremacy in England, and presents a vivid picture of the misery and ruin to which the country was reduced by the ravages of the sea wolves. The hero, a young Saxon thane, takes part in all the battles fought by King Alfred. He is driven from his home, takes to the sea, and resists the Danes on their own element, and being pursued by them up the Seine, is present at the long and desperate siege of Paris.
