Warfare do a set of figures which have apostle infantry packs
So could use those for the earlier period but depends how accurate you want your French... they tended to have short sleeves to their coats and what look like strips of ribbons on the shoulders abit like epaulettes... maybe Warfare will be bringing out more early stuff in the future who knows but if they do they will be AMAZING figures
The French cavalry will be no problem as the uniform didn't change dragoons have those stocking caps and du Roy have armoured back and breast plates and broad brimmed hats rest would just have red blue or grey coats broad hats again they are amazing figures if you check them out
