Hello everyone,
this encyclopedia regarding the town of Prenzlau's history includes (page 88) a brief description of the events there in 1806, followed by an interesting bibliography on the topic: https://www.uckermaerkischer-geschichtsverein.de/wp-content/uploads/2013/04/Stadt-Lexikon-PZ_2005.pdf

Viel dank! I'm going to be revising and updating my book, so these sources will be very welcome to read and probably use.
