Trying to create historical FoG corps for Auerstadt isn't quite straight forward. For one the Prussians created these mini-all-arms corps called 'divisions' and then shuffled things around when they went into action (e.g., the light cavalry and light infantry were taken out of the divisions and put into an advance guard).

I wanted, as much as possible, to create something reasonably close to the lists. But for Auerstadt I needed some modifications. Since there were no Saxons at Auerstadt, I bumped up the maxima for the Prussian troop types by the maxima for the corresponding Saxon troops. That meant:

Musketeers: maximum = 36 + 16 = 52
Fusiliers: Maximum = 6 (there were 4 fusilier battalions totaling 2,350 in the advance guard)
Grenadiers: Maximum = 8 + 4 = 12
All infantry (musketeers, fusiliers and grenadiers) = 36 + 16 = 52
6pdr field artillery = 4 + 2 = 6
6pdr and 12pdr field artillery = 4 + 2 = 6
Light cavalry = 8 + 4 + 8 = 20
Heavy cavalry = 12 + 8 = 20
Light and heavy cavalry = 16 + 12 = 28
Horse artillery = 2 + 2 = 4

I also added the Prussian foot guards (superior, drilled guards) 0-4 bases as an optional troop type.

With that I created three corps, each of three divisions, that sort of reflect the use of the Prussian troops at Auerstadt - an advance corps commanded by Schmettau with the advance guard and Schmettau's division. The main body commanded by Brunswick with Wartensleben and the Prince of Orange's divisions and the reserve corps (usually called a 'corps' in most OOB) commanded by Kalckreuth. Within these corps some of the cavalry is collected into a cavalry division so that no more than one non-advance guard division in a corps is mixed. As it happens I forgot the rule that there's a maximum of four infantry units in a division. Well some of the Prussian divisions have five. I suppose one could create a fourth division to keep within the limit but I'm inclined to leave it as it is.

An alternative to the above is to treat each of the Advance Guard, 1st, 2nd and 3rd divisions of the main body as mini-corps with the brigades as divisions. It matches the historical order of battle nicely, but doesn't follow the list well (e.g., the Advance Guard corps). In addition it gives too much command & control / flexibility to the Prussians. Nonetheless, if one wanted to do that, the changes are:

Advance Guard Division (Corps):
Oswald's Brigade - 2 fusilier units, 1 hussar unit (attached from the cavalry brigade), 1 artillery attachment, 1 officer, 2 rifles
Blucher's Brigade - 3 hussar, 1 dragoon, 1 artillery attachment, 1 officer

Schmettau's Division (Corps):
Alvensleben's Brigade - 2 musketeer, 1 field (6pdr or 12 pdr) artillery, 1 artillery attachment, 1 rifle, 1 or 2 cavalry
Schimonsky's Brigade - 2 musketeer, 1 grenadier, 1 artillery attachment, 1 rifle, 1 or 2 cavalry
Buenting's Brigade - 2 cuirassier, 1 officer, 1 horse artillery (or 1 attachment and 1 attachment for Irwing's brigade)
Irwing's Brigade - 2 dragoons, 1 officer

Wartensleben's and Orange's Divisions follow the same pattern as Schmettau's except that each has only 1 cavalry brigade of 2 cuirassier units. You can either give a horse artillery unit to one of those cavalry brigades or give each an artillery attachment.
