Wonderful. I've been re-reading my Shelby Foote, published long before he became famous via Ken Burns, who in turn, made Chamberlain famous. In Vol 2, pp 501 ff, Foote writes about the attempt to take LRT. I don't want to type in the whole thing, but Foote spends most of his time on Col. William Oates, CSA and mentions O'Rourke, Warren, Strong Vincent, on others for the Union side. Joshua Chamberlain is mentioned once. In Foote's analysis Oates 15th Alabama was already retreating when the Maine regiment launched its bayonet attack. Foote uses Oates quote: "we ran like a herd of wild cattle..."
I am trying to pull together my reactions to Shelby Foote's magnum opus on this re-reading, the first in more than 15 years. I note particularly in this description of the battle on LRT he uses Oates' account extensively and doesn't quote Chamberlain at all.
There are a number of other examples like this. Foote has often been characterized as pro-Confederate, but this kind of sourcing, IMHO, lends a whole new level of credence to this characterization...
By the way, Oates and Chamberlain had quite a correspondence in the 1890's. Both shared a lot in common, including their severe wounds. Both are fascinating men.
