Ha! This is so Wilhelmine; her memoirs are full of things like this.

Indeed! :D I've got to admit, as dumb as this play is: Wilhelmine is done rather well overall (apart from the whole Katte part). She gets some great lines and is generally entertaining. The memoirs appear to be Burte's main primary source and are quoted verbatim at times, but for reasons unknown he does not mention the "Katte, that absolute dumbass, gave me a letter in plain view of Fr. v. Ramen"-scene :P

are the horse's dietary restrictions your own invention or is this in the play? I must know!

I wish I had made this up, but they really are in the play! Katte told people "My horse got terribly sick when we fed it scraps of the bread the army gets, now that we eat all the bread ourselves it's doing great" and people in Monbijou thought it was hilarious. Not even just a small chuckle like "Lol, the army bread sucks", no, he appears to be the star of the party with this story. Katte is also very confused as to why people reacted like that. It's almost as if the "we all think Katte is a swell guy"-algorhythm malfunctioned :'D
