page 507 - nothing about the Saxon - it is about Wellington

That is incorrect. Did you read the paragraph referenced? It is a comparison between Wellington's retreat to Lisbon in 1810 and the devastation inflicted on the Portuguese population and Napoleon's refusal to do the same in Saxony in 1813:

'[Wellington] could be completely ruthless, as in his devastation of Portugal in 1810 while he retreated before Massena into his entrenched position around Lisbon (the 'Lines of Torres Vedras')/ Napoleon was quite impressed, remarking that such measures would cripple Massena's army without a battle. (Three years later, when urged to do the same thing in Saxony, Napoleoln refused; Saxony was an ally, and such treatment would be dishonorable.)

I would also ask you not to make personal, ad hominem comments towards me especially since you insist on referring to me in the third person and don't answer or direct your comments or questions to me personally. You have a very bad habit of doing both and I believe that is against forum rules.

And, again, your derogatory comments about Col Elting and his work is at best inaccurate and at worst a misrepresentation of that work.
