Oooh. That is some really excellent chronological detective work there.

Speaking of timing, if Fredersdorf is involved in Glasow's downfall, what do you think of that coinciding with Fredersdorf stepping down for health reasons?

Also, if Fredersdorf was suspicious of Glasow in the months leading up to April 1757, could that be related to why Lehndorff thinks he retired partly for reasons of jealousy? Maybe Fredersdorf was vocal about his suspicions and Fritz didn't listen?
