Richard I and the Science of War in the Middle Ages

A couple of random notes on an essay about strategy/tactics in the middle ages, I guess made relevant by the same things that make the military relevant, and also because the Middle Ages seems like a somewhat related (and mentioned elsewhere...?) time period in terms of anything from power structures/state structures to a time of guilds and bandits and networks and nomadology...

- campaigns w/o battle vs. fighting on the march vs. pitched battle

- war as 'strategy of maneuver' requiring mostly effective administration

- the dominance of the fortified strongpoint meant that wars of attrition were dominant (rather than battles) ... leads to the importance of garrison troops, artillerymen (engineers), bowmen, incendiaries [guys tasked with the systematic razing of villages] and foragers.

- a War Machine (Delezue/Nomadology), no?
