Phew! that's a relief Michael as I rightly guessed you were a few miles up that dusty Montana road in your knowledge of the characters and the fight. When you asked me to recommend any books to you I did say my recommendations for you would be different than the ones I offered Mister Dave who by his own admission was a first year student of the fight.
I am really glad you found the book as interesting as I did-no mesmerizing is a more apt descriptive in my feelings after reading it twice and you are correct not an easy read. But when you eventually decipher where the characters were and more importantly when and how that fits into the time-line of the battle I was completely sold.
Two particular quotes that Gray makes about Custer and where it could have gone wrong aligned with my thinking out of all the books I have read on the LBH.
1. A simple battle plan that he hoped would stop an Indian left flank escape
2. He believed and expected no doubt right up to receiving his two bullets that Benteen would ride up with his troops and ammo packs.
Also Gray's analysis of Curly's testimony-that for years had been discarded fitted almost perfectly into his time-line using topographic info and positions of who was were. I'll say it now a brilliant book and I seriously would have paid for the book if you had not been satisfied-but I guessed I was on to a safe bet
