So, since I discovered this sub, it's become a personal goal of mine to get a flair with that subject, but I'm having a hard time finding a starting point. Here are a few things:

• The book list didn't really have a whole lot about pre-Conquest England, and next to nothing that really dives into the details of battles and the politics surrounding them. The only thing that jumped out at me was Fleming's Britain After Rome, but the description made it seem like it wasn't what I was looking for. I recently read The Norman Conquest: The Battle of Hastings and the Fall of Anglo-Saxon England by Marc Morris and this is (mostly) the sort of book I'd like to read on the subject. It talks a lot about the politics in England before, during, and immediately after the Conquest, as well as the effects that certain technologies had (specifically the rise of the castle in England). It does go into a bit of religious and architectural detail that I think is extraneous to my goals, but overall I found it extremely useful. Does anybody have any recommendations?
• I've found that most of the books that cover early-Middle-Ages Britain are involved mostly with the social and cultural effects of the Anglo-Saxons. Being that I'm looking to focus more on the martial aspect of the history, I'm concerned that these books won't suit my immediate needs. Are there any books that anybody knows of that are focused on my interests? Specifically, I'd like more information on Cnut the Great and his conquest of England.
• I have a feeling that the best place to find more information in the post-Conquest era on the subject would be in biographies of important martial leaders. What are some names I should be looking for? Are there any biographies that are a must read?

I don't know how long it's going to take for me to get the knowledge I need for this, but I'm profoundly interested in this stuff either way and am prepared to consume as much on the subject as possible.
