Kevin, I think I will lay my cards upon the table and depart from the game. I do not mean to be cruel, just forthright, as in ten years of having these conversations, I've never known you to respond to nuance.
Nothing I have read by Col. Elting suggests he had much familiarity with Russian practises, unlike, for example, Christopher Duffy. So to cite his opinions as an argument of authority does not advance the conversation, and to cite a particular reference without knowing anything about it, is foolish. L' Armée Russe... is all about uniforms and organization, nothing about artillery, and betrays your unfamiliarity with the area.
As for the rest, you merely confirm what I said. Sure, 12lbers battered structure better. Were they worthwhile? It seems our comrades here can straighten both of us out. Apparently there was some contemporary investigation of the question. Napoleon did competently conduct a siege operation, something that can be book learned, (and yes he competently massacred a mob, rather beside the point) and soon moved on to bigger things. And explaining that French artillery education was suplemented by training by the NCO's and men, rather makes the point that actually shooting was something understood by the troop and absent from the education.
