I quite like the idea of playing Nordlingen. This order of battle was from From Slitherine Forum: Nordlingen After Action Report. I have:
Fields of Glory Renaissance has a collection of army list books.
I’ve got most of the figures necessary for a Spanish army for the 30 Years War and 80 Years War in Field of Glory Renaissance. The Spanish of this period are represented by two army lists in the army list book Wars of Religion: Western Europe 1610-1660: Later Imperial Spanish (1621-59) and Thirty Years’ War Peninsular Spanish (1635-59). Both, of course, have a starter army. The armies are fairly similar but they’re not what I’m looking for. I want an army for the Battle of Rocroi (1643).
