Most of the preparation work went into getting the positioning for the messenger right. His arms are different ones selected from the bows and bills box, with the hand holding the letter cut from one of the crosssbowman's hands I think. The long riding boots were added from green stuff for the turnovers and the liquid green stuff to bulk out the rest of the legs. The man wearing the coat uses the plastic arms of the drummer from the Mercenaries box, with an altered hand and a bit of cutting away to hold his sword.
The halbardier, who's biding his time, is a metal artilleyman with a simple swop of ramrod for halbard. The herald is also out of the box, but on a HYW horse, as I wanted a passive pose.
