Aha, thank you! And yep, Horowski gives the date as January 11. It's the same day that Grumbkow is in Crossen about to unintentionally drink August the Strong to death.
Oh, Horowski says that Grumbkow had this practice of getting the cook to boil water for him to create bubbles, so that it looked like champagne, so that he could pretend to be getting drunk like everyone else while really being sober. Then Horowski presents evidence that Grumbkow probably drank a mixture of champagne and bubbled water, so that he was neither as drunk as he pretended to his dinner host nor as sober as he pretended he'd been when he wrote up his official reports.
