At one point a villain the execution of Louis XVI happens in the background.
I think this is a mistake, second-last paragraph on the second page. Having not played the game, I'm not sure what the villain is doing, but they need a verb of some sort.
His attitude toward the upheaval in his country seems to be that it's a distraction from his revenge, and it leaves me credulous as an audience member.
Another, from the first paragraph of the last page; I think Rath meant 'incredulous', unless he actually does find Arno's detachment easy to believe.
Anyways, an interesting piece. I'd disagree about the Sharpe series being a good example of historical fiction because of it's treatment of class conflict, as Cornwell clearly cares more about the campaign itself, resulting in the plot of most of the books boiling down to, "Rich people suck donkey wang, Sharpe is rugged and two-fisted, Wellington is a Magnificent bastard."
