I spotted this while I was on the Pen & Sword website, preordering Henry Hyde's forthcoming Wargames Campaigns book. Since I was painting an awful lot of Norman cavalry at the time, I thought Why not? and got myself a little treat.
At 119 pages, this is a quite useful guide to a very popular period. Daniel Mersey surveys the history, what the armies looked like, and how they fought. The major battles, campaign ideas, scenarios for fights before and after the major battles, figure ranges and rule sets available. I even learned a thing or two. The Conquest didn't end on Senlac Hill but it took a few years of brutal low level fighting to finally subdue Saxon resistance. Plus there were the Scots and Welsh. So loads of scope for small scale games using Mersey's own very popular Lion Rampant rules. I'll definitely play some of his scenario ideas.
This book is great for a novice to the era and even worth a read for gamers who have already researched the Conquest period.
