Tbh, I intended to stay away from any attempt to unravel this hotchpotch patchwork of singled-out bits of knockledge, some half-knowledge and some portion of lack-of-knowledge stitched together and gaps filled with contrafactual assumptions to someones taste. It would very likely need a several hours long lecture.
But ... as you asked for
I suspect
NoMommsen is more familiar with the detail than I, ...
Lets perhaps begin with some detail :
9th army is not there until 30 August ...
You probably refer to the 9th russian army ?
Well, first part of the russian 9th army - more precisely parts of 37th division of XVIII.Corps - began to detrain off the railtrack from Iwangorod to Lublin on the open field at 26th/27th August parallel to parts of 46th division of XXV.Corps and 80th reserve division sent from russian 5th army (
at this point of time Plehve seemed still feel able to 'afford' this lending of troops as the "Battle of Komarow" hasn't become as ...hard to him as 2-3 days later) as reinforcement comming from the opposite direction on the same track.
Thereby they caught the austrian I.Corps - mainly 12th and 5th division - in its left/northeastern flank while slowly advancing at Lublin from southeast and south (
together with austrian V.Corps) despite almost complete exhaustion - but he russian XIV. and XVI. Corps of russian 4th army were in no better, perhaps an even worse condition being constantly beaten and driven back.
However, without these reinforcements of fresh troops - maybe aside the parts of 46th division from 5th army - russian 4th army would have been driven fürther back ... as they were alraeyd beaten by austrian I. army (you remember? "
Battle of Krasnik"?) leading to the austrian capture of at least Lublin, with the germans (actually another though of 'only' second line formation : Landwehr-Corps Woyrsch)hot on their heel towards the Vistula crossings south of Ivangorod.
Only at 1st September most the russian XVIII.Corps was finally deployed along the Chodel-creek to the Vistula merely checked by altogether about 2 to 2 1/2 divisions of 2nd line troops of the so-called Armygroup Kummer.
Just another wee, "irrelevant" detail refuting at least one of your statements. ... letting once again the rest of your statements look ... somewhat weeker, dear
@Gannt the chartist
And of course the above named battles only show how
... the Austrians are so incompetent ...
