This is true until you remove the logistical structures of the Entente forces - which counteracts the Germans' own loss of cohesion. I intentionally made the offensives see only limited changes early on, for example; the diversion of forces to prop up the northern 'wing' of Operation Michael. By doing that they push further and thus cut off the main axis of advance of the Australian brigades that IRL defended Villiers Bretonneux. By doing that the Germans almost certainly would have met no opposition, or at least minimal opposition, to their capture of the town and thus establish artillery positions there. By doing that, Amiens falls under fire - and thus makes it largely indefensible and pointless to continue to hold - the train station doesnt work if it's being shelled directly.
Secondly; the attack in Georgette where historically German forces attacked Mount Kemmel. This was historically held by a small number of extremely ill-prepared French units that, again, are not here. Obviously that doesnt mean there would be no troops ittl, but whatever forces are there would be spread just as thin and exhausted British forces - who ittl are attacked rather than holding back after the Army actually listens to it's Chief of Staff. The fall of Mt Kemmel means the almost certain collapse of the Ypres wing of the British line, which would force a withdrawal of Ypres (as was initially ordered by Haig before it was countermanded by Foch). The absence of Amiens as a logistical hub before Georgette means a weaker British line (subjective but still plausible) which means that German forces can push on to near Hazebrouck and again break the British logistical structure - even without capturing it. Thus forcing a total British withdrawal back to the Channel ports (again, as Haig ordered irl and would have ordered in such a scenario as the front would become logistically untenable).
So, to conclude; Saying...
Is kind of a frustrating point to make. To dismiss the timeline for a sole reason which I've gone to great pains to outmanoeuvre, and then try to make up for it by saying "good writing tho" is nice, but also doesn't actually make me feel any better lol.
It's entirely plausible.
