The following year, King Edward dies shortly after arriving in Scotland, and the Prince of Wales takes control of his father's forces. In defiance of his father's dying wishes, he orders his late father's burial in Scotland. Bruce decides to fight the new king in a pitched battle at Loudoun Hill, despite being outnumbered six to one. Clan Mackinnon arrives to aid Bruce. Edward's army is composed almost entirely of cavalry, so Robert overcomes this army's size disadvantage by ensuring that during the battle, the English cavalry charge into a spear wall hidden by a ditch, and thus incur heavy losses. Many horsemen attempt to attack the flanks but become bogged down in the mud, just as the Scots anticipated. As the English knights fall from their horses, many are slain, and the battle becomes an open brawl, wherein the ferocious Scots prevail over the disoriented English soldiers. Realising the battle is hopeless, de Valence orders a retreat. However, determined to kill his nemesis, Edward does not join the retreat. Instead, he engages in a duel with Bruce as the Scots look on.
