If you mean Nafziger's "French Forces of Maréchal Oudinot 15 August 1813" 813HGA.pdf, I have checked that one.
The problem with it is that it's set before the Battle of Großbeeren, but even if I counter that with Nafziger's 813HGF.pdf that lists the casualties at Großbeeren I'm still left with a note that Ney took approx. 6000 replacements(these are not the Polish Division under Dabrowski) up at Wittenberg and I wouldn't wonder if that would have been mainly Saxons.
