A quick look in Peter H Wilson’s Europe’s Tragedy has Pappenheim on the left (presumably with a lot of cuirassiers) and Furstenberg on the right with League ‘heavy’ cavalry and Isolani’s Croats on the extreme right, with Erwitte with more cavalry in reserve behind Tilly’s centre/right.
His sources are not clear at a quick glance as he doesn’t have a proper bibliography and the notes are not revealing a lot on primary sources on first inspection. (I’ll have a closer look later, probably).
Daniel Staberg usually has some info which looks good – although he can be frustratingly dismissive of everything except Swedish sources. I wish he’d write a book or push someone else in the way of some of his research so they could write it.
