I'm considering writing a novel set during the Befreiungskriege, and continuing to Ligny and Waterloo. The main character would be a Prussian junior officer from Brandenburg or Pomerania.
What regiments would allow for the most drama and action in this time period?
The main character will likely be a nobleman, as it seems officers being promoted from the middle class or from the ranks was very rare.
James,
good idea! I would recommend the Neumärkisches Dragoon Regiment, especially its Jäger squadron. For more data see Archibald v. Keyserling's report on Thielmann's raid ( https://books.google.de/books?id=5J5DAAAAcAAJ ) and the notes of Louis v. Rauchhaupt ( https://books.google.de/books?id=mwYjAwAAQBAJ ). The squad was the only Prussian unit present at the battle of Hanau and saw many other adventures, e.g. the skirmish of Zeitz .
Best wishes, Thomas
