Hi Robert, nice to hear from you again
"Is all this discussion really important to a comprehension of Napoleonic history?"
The dates of battles, who won, what units and leaders were involved,what color uniforms they wore, and who had what type hats. They are all some part of comprehending Napoleonic history.
So, I think, are guestions as to "Who was Napoleon", and what made him tick.
Until someone comes up with one answer to those guestions which everyone else agrees to; I think the field is open to all.
