It´s reckoned there was around 14,000-15,000 english infantry at Bannockburn, a large number of those being archers.
The new archer stand brings the foot up to 106 bods, 48 infantry + 58 archers/crossbows, so at my Chosen Ratio of 50-1 that makes 5300. Still pitifully low than the total needed, I´d have to paint another 150 - 180 bods, but getting closer.
The entire "English Army" Ranged weapons sectionMedieval Crossbowmen set. At the Ratio of 50:1, It would be over the assumed numbers of crossbowmen present at the actual battle but it will make an even 6 stands.
