So I know I am late to the party, but I have just thoroughly enjoyed your TL.
I do have some notes regarding the Antwerp '14 situation. Or more specific the retreat by the Belgian field army + 20k fortress troops along the 10 km wide strip between Gent and the Netherlands. As this is literally in my backyard my attention was drawn to this route.
First of most of the troops were on the Eastern side of the river Schelde, meaning they would have to cross(no bridges or tunnels yet). However the Belgian army had planned for this eventuality and a company of engineers with equipment was in place. In OTL they build this bridge
It was mostly used by the masses of refugees trying to get into the Redoubt. In this TTL it would have been used by the retreating Army, as you can see this would already mean abandoning their artillery train, and most likely almost all their supplies.
Then they would entrain on a local and single spur train line to Zelzate and from there to Eeklo and on to the coast. See the map underneath.
Railroad map of the area around Antwerp in 1914, taken from a excellent paper by Paul van Pul 'De Belgische militaire onderwaterzettingen rond de Versterkte Plaats van Antwerpen in augustus en september 1914' it is however in dutch.
As you can see if the Germans own Dendermonde and the slightly of map Gent, the only rail route out of Antwerp, passes through St-Gilles-Waas and then on to Zelzate.
Now Zelzate was a small town along the Gent-Terneuzen canal with two new bridges.
One for road and rail traffic each. As you can see without the bridges the canal would be a major barrier to troop transport going across. And as all the pontoons had been used to cross the Schelde, no easy fix is possible if the bridges are gone.
Please note that those two bridges would have been within reach of the forces in Gent. They would have to commandeer one of the cargo ships in Gent and sail down the canal for about 5km and open fire on the bridges with one of their 60mm Bts KL/21 cannon. Something well within the capabilities of a Naval detachment.
Any commander who would not undertake such a simple and basic encircling maneuver, would be shot for treason.
So even if you did not intent to write a wank, with a capture of the King and army, POD you chose still would have lead to one. Now I wish to reiterate that you wrote a most enjoyable TL, I just wanted to drop some local knowledge on you.
