I recently had a slight disagreement with someone over your Starbuck Chronicles. He said that he felt that reading the Starbuck Chronicles (without prior knowledge of the US civil war) duped him into believing the lost cause myth that the war was really about state writes and not about slavery.
My counterpoint to this was that Nathaniel knows he is on the wrong side but only continues with it due to he determination to do the ultimate act of rebellion against his father. And that's what made the series interesting Nathaniel a good man fighting for a bad cause, contrasted with his Father Elias Starbuck a horrible man fighting for a good cause.
Sorry to drag you into this but I wonder was that assumption the reason you choose to write from the Confederate perspective.
I’ve always liked my protagonists to have a conflict of interest – and you’re absolutely right in saying that Starbuck knows he’s on the ‘wrong’ side, but friendship, loyalty to his comrades and a fair bit of pure cussedness (his father, yes) will keep him there. He certainly isn’t convinced by the states rights argument (a lot on the Confederate side weren’t either). It’s the same divide that keeps Uhtred a pagan, and Sharpe forever uncomfortable in the officers’ mess!
