I've decided to start a project around the period of "The Anarchy", the Civil War in England (which also involved Normandy and Scotland, from what I can tell), between 1130-1150 (rough dates). Intending on 10mm, and order placed for a "Norman Starter Army" (Lancashire Games, which I can mix with the Saxon I have for some variety).
I have a book coming on the subject (Stephen and Matilda : the Civil War) and have a few general resources on Feudal/Early Medieval forces, but would be grateful if a more knowledgeable person could point me towards relevant reading material.
