Tried recreating Falkirk in Custom Battle, VH difficulty. I had mostly Militia Spearmen, Highlanders, Peasant Archers, light cavalry, couple of Knights, total half-stack. English had mostly dismounted/mounted Knights, Longbowmen, and some levies, total full-stack. I took the high ground, formed line of shiltrons. Extra height allowed my archers to meet Longbowmen's range. English still faring better, so I rush my Border Horse downhill and rout most of the Longbowmen. These Border Horse then lure the English cavalry uphill, who slam into the schiltrons. Both sides take heavy casualities at this point. Just as it looks like the English have broken the Scots spearmen, the Highlanders charge through the gaps between each of the Schiltrons, and the fearsom Higland charge turns the tide of the battle. The cavalry rout, and the English send their infantry uphill. The battle could swing either way, so the Scottish Knights charge round the right flank of the English infantry, focusing on the one flank as they lacked to power to fight on both sides. It turns into a rout on the one side, and so the cavalry continue to the left flank and mop up the English there.
