If Napolean III personally escapes capture at Sedan is his government still doomed? Will legitimists or republicans still try to depose his government even while he is free and trying to rally new armies either from Lille or in the south?
I am thinking that with Napoleon free in France, but with a competing regime in Paris, the war could go on a lot longer with neither competing French government wishing to be the one that surrenders. Would Napoleon III have fought on?
Any thoughts?
(I am trying to decide whether to write this TL or the 1860s China one I've been thing about).
