Yes, this is the level of warfare that interests me!
I'm picturing neighbouring nobles having their own little feuds and private wars.... And employing mercenaries (including Italian, Swiss and English).
I'd love to find some accounts of such conflicts to read... perhaps I need to learn German?
Oswald von Wolkenstein, a Tyrolean knight and minstrel, even wrote a song about some skirmishes of the war, he himself, his brothers and allied nobles had waged against the duke of Tyrol.
And - as Arlequin said - if you take account of the (Imperial) Cities you will find a lot more of those feuds and private wars. Even the
First Margrave War was characterised by raids on cattle ranges, farms and settlements. The typical report in one chronicle of this war was, that soldiers on horse (Reisige) and on foot (Fußknechte) and wagons marched out of the city, invaded enemy territory and tried to pillage and burn down the assets of the opponent.
Eventually Nürnberg had even an extra feud book to list all the knights and nobles who declared war against her.
