From about 793 all through up until the early 800s England Scotland Ireland are getting hit a lot. Even if one Viking ship with 30 Vikings in it pulls up near the shore somewhere that's quite a bit to have to deal with especially if they're back in their ships in 20 minutes. These are devastating and very difficult to defend against raids. The era of very easy targets is going to end in the not too distant future for the reasons we mentioned earlier about for every action there's an equal and opposite reaction.
