Book title needed

I am working away at a book about French military history in the 14th century, and I've just come to the realization that my planned title probably won't work out.

I was thinking of calling it Men-at-Arms, which goes nicely with my previous book Deeds of Arms. It is also appropriate because people holding the status of men at arms hold a key position in the mental universe of the document I'm working on. It's men at arms this, men at arms that, men at arms the third thing.

So if this is the case, why not use Men-at-Arms?

Well, there are two other books that already have the title. One is a general history of -- men-at-arms! I have never read it, but a former colleague of mine used it in his military history class, and he had a good instinct for what students might find accessible. My guess is that this book is used by a lot of profs. The other book is even worse news. Terry Pratchett has written a book of that name, and when you go to Amazon.com and put into words men at arms, you get screens worth of Terry Pratchett-related material before you ever find anything else.

So I hesitate to use what might be the most natural title in fear that potential readers will never find the book. Is this an unreasonable fear? If I am right, what might be a good replacement?

If you want to help me with this, let me tell you a little bit about the book's subject matter. in about 1350, a prominent French knight named Geoffroi de Charny was inspired or even asked by the King to put together a list of questions about how the law of arms, which regulated the relations between one night and another, applied to three knightly activities, jousting, tournaments, and war. Charny came up with some interesting legal problems, which are group of prominent French knights were to sort out. We don't know if this actually happened, but we have no answers to these problems, which is why most of you have never heard of Charny's questions. I am using the questions, however, to show what Charny thought was most important about the law of arms, as well as a number of other issues of honor and military science. Even with no answers, questions themselves stake out some interesting territory. I have already talked about the jousting and tournament questions in a book called Jousts and Tournaments. This book is about the much longer section of questions on war.

Given this, relevant subjects touched on by this book include: Royal reform of the French army, the Hundred Years War, the law of arms, Charny (increasingly well known among fans of chivalry), chivalry (but not as much as you might think).

I would like a title where the first phrase or main title is not obscure. There are too many academic books where a boring subject is disguised behind a title like this:
Long Words Bother Me: Winnie the Pooh and Heiddiger's influence on modern readers. Not a very successful disguise, is it? But people do this all the time. I don't want my very interesting book to look like this fortunately fictional monograph.

I appreciate all serious or hilarious answers. If it is just vaguely cute, though...
