I can't quite see the value in quoting from an English translation from the French - an English translation from the German would be more to the point since Thomas found the original passage in the German. Both volumes of the French Odeleben can be downloaded from gallica.
I don't think the piece is significantly inconsistent, it claims Napoleon gave orders for the devastation of the right bank but that it was not carried out: two reasons are given, which look confusing, but there is no reason why they cannot both be true 1) the French generals did not carry out the order, 2) the Allies advanced too rapidly to for it to be carried out. I can well believe the French took everything that could be moved with them but cutting down fruit trees would probably have seemed a waste of time.
Proof is still lacking that Napoleon ever gave the order though.
