Alfred the Great; Viking Invasion

The Great Army of the Danes invades Wessex, and, after two sieges, Alfred forces King Guthrum to agree to withdraw. When the leader of the Great Army breaks his word and invades Wessex in early winter, he nearly succeeds in Capturing Alfred and destroying the last independent Saxon kingdom in Britain. King Alfred hides in the forest, until he finds a base deep in the fastness of a marsh. From there he starts to strike back. He deals with the traitors within, and sends the word for his fyrd to gather in when winter ends. Spring finds his men rallying to his banner, and Alfred defeats the Danes. Britain is saved.
