What is "generalfeldwachtmeister"

Generalfeldwachtmeister is a historical military rank of general officer level in the armies of the German and Scandinavian countries, corresponding to the rank of maréchal de camp in France.

He ranked above all brigadiers and colonels, and was subordinate to the rank of lieutenant general (Generalleutnant) (in Austria, Feldmarschalleutnant). The title may be literally translated as "master general of field guards", reflecting the original task of the office holder: the inspection of the pickets and the supervision of the dispositions of brigades and regiments in the field and on the march.

The title was superseded in the 18th century by Generalmajor (i.e. major general).
