Indeed, an excellent read. The logistical aspect of the war almost certainly was the key aspect of Napoleon III's downfall.
I'm a long away from being sufficiently knowledgeable about this war, but I understand that the Napoleon III also realized he needed long ranged breech loading rifled artillery. The problem as I understand it, was money, though he tried to get around this by buying surplus artillery from the US after their Civil War.
The lack of modern artillery, again as I understand it, forced them to adopt defensive tactics where they could take advantage of their longer ranged rifles and the Mitrailleuse but left them vulnerable to flanking, which the Prussians pursued with great zeal. The Prussians Krupp artillery also allowed them to pound the hell out of any French defensive position with impunity before assaulting it.
Perhaps you could comment on the tactical side of things and give us your view on how it played out.
