Staatsminster: Not a hundred percent sure. What I have is a third brother I've uncovered, Carl Aemilius, who died in 1757, and a source saying that the Staatsminister von Katt is his "second" brother. Now, both the aforementioned general brothers were alive in 1760 (they are a Generalleutnant and a Generalmajor, so I'm guessing Lehndorff can just say "General" in his diary and be done with it), so there must be a fourth brother who is the red-headed Staatsminister.
Meanwhile, more gossip! This time from German Wikipedia. After having distinguished himself, Johann Friedrich von Katte, first cousin of Hans Hermann, was made interim commander at Breslau (modern-day Wrocław--see, I know these things!) when it was besieged by the Austrians in late 1757. He negotiated the surrender of the city, for which Fritz had him court-martialed, imprisoned for one year, and kicked out of the army. This is approximately five months after AW's cashiering. And about two years before he does the same thing to Finck for surrendering not long after Kunersdorf.
...Yeah, his generals were a bit nervous. No wonder this turned into a war of attrition.
