To come back to the (lack of) discipline in the Grande Armee: if N had seen it as a priority, he would have done something about it. If he knew what was going on, yet did nothing to rectify it, that is `not very clever`.
If he did not know what was going on, that is dummer still.
Was he sitting in a corner for 8 or so years going `La, la, la - not listening!` or what?
