There was a critical moment, when a Swiss regiment detached from Soubise was striving to come and help the right flank of Stainville who was being pressed hard. This regiment was enfiladed by the Allied cavalry who made a double move and, worse than that, diced to turn and face and failed.
For this particular instant, many factors were involved:
1. This Swiss regiment (Diesbach), belonging to the middle French line (Soubise) was ordered march to help Stainville's right flank and bar the way to the 1st Column of the allied cavalry.
They brought 1 for two rounds and were delayed to place themselves level with Stainville.
2. The Allied cavalry brought a 6 and was allowed to make a double move, covering a great distance, falling unexpectedly at the flank of Diesbach.
3. Diesbach, not having enemies frontally, according to the rules, could turn to face, bringing 4, 5 or 6. They brought 2.
It was really a bad moment for me, as the French player in this game and in a critical phase.
The easy demise of the Swiss opened the road to the Allies for turning Stainville's right flank.
Later, they had free cavalry to send and fall at the rear of Soubise's cavalry fighting near Wilhelmsthal.
Two pics say it all: Please, note the line where the two tables join. The Swiss unit is standing astride.
They did not manage to move, while the Allied Cavalry was behind Grebenstain (1st pic), until they appeared at their flank (2nd pic)
