As written in my first posting, I chose the destruction of Castle Hohenfels as the central event for my novel. Prior to the slighting of Castle Hohenfels, the castle was a few month under siege. This siege was prepared and executed by an army, organized and led by the cities, Speyer and Worms and the counties Sponheim and Bolanden.
But, the years around 1350 were difficult and dominated as well by the outbreak of the black death in Central Europe, Flagellant processions and mass murder of the Jews.
Not a good time to gather your soldiers to let them siege a small castle in a shire in the back of the beyond.
So, the central question for me as an author is:
Why did two really big and powerful cities (for medieval criteria) declare war on the small shire Hohenfels in the middle of the black death area? Just because the Hohenfels Clan was of danger to the next trade road? Is this enough? What about some unknown political linkage?
