You attempt distraction.
I have been reading of French pillaging activities in Spain, Portugal, Russia and other spots, very regularly, for over 40 years, from a wide variety of international sources. I have yet to find evidence that N managed to solve this, although he did invest a lot of time, money and effort to make it happen in Russia in 1812, but it failed at the first hurdle, as you may read in any account of that campaign.
Strangely enough, the Prussians, up against Riga, and the Austrians and Saxons, down in the Ukraine, ate well, all the way through.
Read any German account of the wars in Spain and see how they got on, using the `Systeme Napolienne`.
My statements may make uncomfortable reading for fans of N, but they are based on many accounts from regimental and campaign histories.
