A gifted politician and soldier from Bohemia, Wallenstein grew in stature to command armies for the Imperialist, or Habsburg cause, fielding vast forces in many battles in The Thirty Years War.  Despite his many successes he fell out of Imperial favour and was accused of treachery and sadly brutally murdered in his bed by an Englishman, Walter Devreaux; a poor end to an interesting life.  

We have him astride his horse in full cuirassier armour, the classic dress of a general of the period. He could equally be used as many other generic generals.
