Hi,
by coincidence, I just stumbled upon an old book, which mentions a “Racek Kobyla” (the name of the historical counterpart of Radzig Kobyla) and seems to be a novel or something like that.
It’s written in german, with the title “Bild und Leben - Eine Unterhaltungs-Lectüre”, which means “Picture and Life - an entertatinment lecture”, written by Moses Isreal Landau in 1847.
Chapter 5 is called “Kuttenberg”.
It can be found via the link:
Just in case anyone is interested
