"French and Russian formations at Austerlitz" Topic

Are there any sources on how the French and Russians adapted their tactics and techniques, especially Davoust's 3rd Corps and the Allied Ist and IInd Collumns which had very reduced battalions from Kutuzov's force? These battalions were down to between 20-50% of theoretical strength and I wonder if anyone have read sources who describe how, if any, the formations were adapted to this personell strength?
I remember Coignet told about how he had to thin his grenadiers from three to two ranks in order to keep up the frontal width of his unit at Aspern. Are there any similar first hand accounts from Austerlitz telling about similiar adaptations?

Not that I've read, but then there isn't much in total on actual low level tactical deployment.

Sounds like a solution looking for a problem. A 5km (or more) battlefront with troops in all sorts of compromising positions and roles, leaves a lot of room for action and not a lot of keeping records.

Goetz has a lot of 'gap/ interval' issues rectified whether actual commanders (at any level) were tacitly aware of them or not, who knows.

I'll bring this up to date.
If you think Davout had a 'Corps' at the battle, you are mightily disappointed.
His force, even before he arrived on person, was a hodge-podge of streaking columns of soldiers who were greatly losing strength every advance [by force marches through the nights as well] they made.

Intial orders were to attain Sokolnitz; updated either midnight (Dec1) or at dawn (Dec2) to hasten to Telnitz and Menitz, the extreme French right wing. Luckily they did.

Each of his 'formations' had to engage at the run when they arrived as the Russians, in particular tried to break out of the Goldbach valley crossings.

This wouldn't stop me modelling the Corps, just that it wasn't complete until the eveing of the battle, still with march losses.
