I appreciate there is a number of considerations to account for, such as did they know which areas these people were coming from (changing over the years), did they have the naval capacity to launch an attack. I have never heard of this type of event taken place, but I am curious if a anglo saxon raid ever occurred on Scandinavia land or for that matter even on the continent?
Sorry for not a reply from an Anglo-Saxon historian and just posting a link to my previous answer to the similar question to OP: The Norse people were shown to be capable raiders, especially in the British Isles. The Anglo-Saxons despite divided were socially and militarily organised, why did they, or others, never seek or attempt to attack Scandinavia?
I'm also willing to complement any additional question.
