The glory of doing his duty to the state. You can't shake your definition, but your definition may be wrong.
Are you suggesting that the mission (and its costs/personnel) was done purely for the emotional reward of a military event the results of which would take months to hear?
Was he saying, "dude man, you get to go KILL people! Let the blood of those wonderful innocent freedom fighters that just want the best for their children drip from your blade until the screams of agony fill the night like a symphony of pleasure!" (maniacal laughter)
Is there a way he could have articulated a desire for success to his subordinate that you wouldn't be able to read evilness into? And, if you can find those words - I think the point from that other author is your words may be synonymous with their concept of glory... and if that is the case, then the harsh judgement that you have of Napoleon as taking military actions for pleasure is wrong.
We are probably just chocolate/vanilla on this one.
