A thread that has not been touched for a while.
I found a new pic:
I think it could be GenLt Briesen, Kmdr 30 Div, X Corp. Yes he had arm injury but there were a few photos showing him inspecting troops with arm sling. Enclosed pic for compariosn. Note position of EK I with spange.
I now agree with Vienna that general ("Y") next to the mystery general's left ("X") was GendA Ulex, Kmdr, X Corp. Another thread clearly showed he had two pips and it was not Cochenhausen because (a) Cochenhausen was a GemMj and (b) no Johanniter Order.

.
Note position of EKI. EKI below pocket. Spange above pocket.
