On the other flank, Somerset threw in his cavalry to delay the Scots' advance. The English cavalry was at a disadvantage, as they had left their horses' body armour at the camp. The Scottish pikemen drove them off, inflicting heavy casualties. Lord Grey himself was wounded by a pike thrust through his throat and into his mouth. At one point, Scottish pikemen surrounded Sir Andrew Flammack, the bearer of the King's Standard. He was rescued by Sir Ralph Coppinger, and managed to hold onto the standard, despite its staff breaking.
