You could call it poor prioritisation - but the first book I've started has really given me a feel for the post apocalyptic style desolation that was Dark Age Britannia following the departure of the empire.
Britain After Rome, by Robin Fleming, covers a massive 600 years of history, but the first three chapters have already got me hooked despite the non-military focus of the book. Robin Fleming really gives you the feel of a desolate and depressed world, the rapid decline of Roman civilisation, and the exodus from crumbling, villa based towns as people re-formed communities in old places of safety such as abandoned hill forts.
Not by any stretch of the imagination a military history, but I already feel like I know the dark ages and have a feel for it's atmosphere. More to follow when I've delved into the other two - Warlords by Stuart Laycock looks particularly promising.
Next up, thoughts on basing, and hopefully some close ups of the new recruits...
