Übergegangen sind danach maximal
101 Offiziere, 3.304 Mann,
19 Geschütze

so maximally 101 officers, 3 304 rank and file - along with 19 guns defected.

I have a PDF in German from a presentation of Jörg Titze who discusses the defection and also includes why the Saxons became more and more fed up with Boney, write me a pm and I send it to you
