It would be impossible in the space allowed to give a full and exhaustive analysis of both the actions of Viking invaders and native English and Irish warriors,a brief look at many issues is necessary for my argument. I have not included a narrative or even an overview of the Viking Age, simply because such information is readily available in many forms and is written by scholars far more qualified in the field. There was originally going to be an entire section on the Vikings in Francia, for which there is perhaps the best and most reliable evidence – and a discussion of the impact of post-Viking Age sagas on modern interpretations of Vikings, but there simply was not enough room.
Gratitude is extended to Professor Ian Moxon, who though not a medievalist was kind enough to provide me with his excellent and very useful translation of the The Life of Anskar, which hopefully one day will see the light of day as a published piece for the benefit of other students without a good grasp of Latin.
Thanks also to those who read all or some of it during the making, especially Professor Ian Wood, Freddie, Peter and Tamsyn who pointed out the worst of the mistakes. I can only accept responsibility myself for the remainder of them.
