He fought at the siege of Loja, where he helped to defeat the Moorish forces by leading an attack to scale the city walls. In the fight, Edward was hit in the face by a rock thrown by a defender. He was knocked unconscious and his front teeth were smashed, a disfigurement he considered a badge of honour. He was visited in hospital by the king and queen, who sympathised with him over the loss of his teeth. According to the chronicler Andrés Bernáldes he replied, "Our Lord, who reared this fabric, has only opened a window to discern more readily what lies within". In the following year, back in England, he played an important role in defeating the rebellion of Lambert Simnel, when he was placed in command of the light cavalry, sent north to make first contact with the rebels. His forces repeatedly harassed the rebel army in a series of skirmishes in Sherwood Forest, forcing it to slow down and giving the king time to build up his army before the main battle. He seems to have intentionally adopted the "Moorish hit-and-run tactics" of the kind he'd seen used effectively in Spain. His cavalry joined the main royal army before the decisive Battle of Stoke, forming its right wing. In the following year he was made a Knight of the Garter. In 1488 the Duke of Brittany appealed to Henry for help when he was once more threatened with invasion by France. Henry attempted to negotiate a settlement, but the French decided to invade. Edward asked Henry to allow him to raise a force to support the Bretons. Henry was unwilling to commit to this, and so Edward collected men from the Isle of Wight on his own authority. He managed to gather a small force of between 400 and 700 archers along with 40 of the local gentry. He sailed to Saint-Malo, plundering a French ship on the way. The Bretons decided to make the English force seem larger by dressing 1,300 of their own men in English colours, possibly to frighten the French with the fearsome reputation of the English longbowmen. At the Battle of Saint-Aubin-du-Cormier (1488) Edward's force formed the vanguard of the Breton army. He led a bold attack on the French in the opening stages of the battle, but a French counter-attack on the weak Breton centre broke their position and the Bretons were defeated. Lord Scales' force was almost completely wiped out.
