The Battle of Maldon was a catastrophe. The brave last stand of Ealdorman Byrhtnoth was never going to change that fact. He was the leading man of Essex and the second most powerful Ealdorman in England and now he was dead. And his Fyrd was defeated.
To top it off, there are indications that, facing the strength of the Viking fleet (and likely in response to the failures of English leadership) some were looking to switch sides. We know of at least one Noble who attempted to defect… AEthelric of Bocking… but we can’t be certain that he was alone. There may have been many nobles like AEthelric, who just went unrecorded.
Things in England were bad.
