Another depiction of the murder of Wallenstein

Can't read the key but it's an interesting picture. Just had this transcription from Norbert
the nakme of teh pic is: The murder of Wallensteins Officers, drawing by feather, anonymous
the notes on this, as far as i can make out:
a,b,c,d reads as Obristen.. whis means Colonel´s ... maybe "Colonel butlers" soldiers or dragoons e , f illegible g Tertzsky which is Trcka, one of Wallensteins subordinates and relatives i Rittmeister... which is a title for an officer
