It appears my wish for a good Adobe Walls (the 1864 one, not the legendary 1874 affair) book may be granted with the June release of Alvin Lynn's Kit Carson and the First Battle of Adobe Walls: A Tale of Two Journeys from Texas Tech University Press.
A 2013 book about another important Civil War's Indian Wars event from the same year, Ari Kelman's A Misplaced Massacre: Struggling over the Memory of Sand Creek was recently awarded the Bancroft Prize. It's too bad the publisher never sent me a copy of that one, as, from what I can tell, it's right up my alley. I'll definitely pick up a copy at some point. For a hoot, check out the patently stupid negative "reviews" on the Amazon page.
