Every pikeman either had the pike removed and replaced if originally already Holding a pike or in some cases a halbardier was converted to a pikeman ..using 0.4mm Florist wire .
I think only about 10 or so haven´t been converted in some way, wire pike added or head swop or both.
The one at the front in this pic (they were all halbardiers and all ended up in the burgundian pikeblock).. The original halberd covered his face (
