Don't you mean rather "bold" than "honest" ?
As a first shot :
- Falkenhayn is overruled, H-L get their wished for "priority" for the east, with the western front going into more of the defense mode and no "meat-grinder"-at-Verdun-attacks
- more troops for the east
- "preliminary"/"preparing"/"probing" and rather limited attacks in the winter (Nov./Dec.) maybe/likely towards Riga and possibly Rowno on the southern front. Riga very likely to be taken (kind of 2nd winter-masurian), Rowno possible - with german support of AH-forces, at least Dubno likely
BIG question for the russian where now placing their troops ? ... for whatever might be equivalent to a "Brussilow"-offense ITTL ? However, lets assume the russians try a "Brussilow" also ITTL, be it in the north or the south.
Even IOTL they struggled to get their troops together - in time. IOTL it was intended to start in early May (or even earlier ? Don't have my sources at hands atm.) ... and started early June.
So ... ITTL
- April/may the BIG offense in the east starts :
- North towards Lake Peipus (general direction)
- South towards Shitomir/Vinnitza (general direction
- they won't "encircle" larger groups of russian troops but most liekly will "grind down more russian losses than receiveing losses themself, given the OTL-performeance of german troops against russian troop in the moving war.
- however, they will in any case be - once more as in Poland 1914 and 1915 - the "first" to start with tzheir operations, thereby greatly disturbing any build-up for an ITTL-"Brussilow", making it not happen at all
- that in turn would also most likely butterfly the rumanian entrance on the Entente-side away ... btw.
With the russians very likely heavyly beaten in the first 4-8 weeks I don't see any reason, why the CP forces sgould not be able to perform a similar advance as after Gorlice-Tarnow with a front in autumn 1916 running from
Dorpat in the north
Minsk or even the Beresina in the midth
and south of the Pripjet around/at Shitomir -Vinnitza - Mogilev
All these distances are well comparable to what they managed in the 5 month of offense in 1915 IOTL.
So, crys for "logistics, logistics" are rather moot ITTL ... this is still horse-age warfare and no Panzer-Divisions WW2.
Another "Winter-Battle" and the CP forces are at Narva and possibly Kiev ... not to forget the possiblility ITTL of rumanians trying to reach the Dnjestr and maybe even Odessa.
Thast might now be an ... interesting Christmas at St-Petersburg and Moscow
Meanwhile the western Entente runs one offense after the next for the "relief" of russia only to be ... what also happened to them IOTL :
being slaughtered in and before the trenches without much of an impact (see
@Alanith post above)
