In his letter to his wife Klara of Janury 1794, Scharnhorst writes about the possibility to get the rank of wirklicher Capitän, without getting a company.

Shows that the organisation of the Prussian army can't be projected 1:1 onto the Hanoverian army.

Maybe the best translation in to English would be "title captain" or "captain 2nd class", with a short explanation of the Hanoverian rank system.
