Chivalry, an important topic in several of Twain's books but subject to 
some major misuse in recent "news".  I was prompt to purchase a book for 
my Kindle on the history of Chivalry and was struck by a couple of 
Twainian moments.  "The rise of the knight (miles in the Latin sources) 
has been carefully tracked by historians."  I was reminded of the heroic 
character in the Price and the Pauper.  Could there be some connection 
with Twain's choice of names for Miles?

"A knight should not kill an unarmed foe, two knights should not attack 
one, and knightly prisoners should be held with dignity, released on 
parole and ransomed in accordance with their means."  This seems in 
contradiction to some of th action in A Connecticut Yankee.

Just a couple of thoughts....
