The war began with French successes, but the talents of John Churchill, 1st Duke of Marlborough, and Eugene of Savoy checked these victories and broke the myth of French invincibility. The duo allowed the Palatinate and Austria to occupy Bavaria after their victory at the Battle of Blenheim. Maximilian II Emanuel, Elector of Bavaria, had to flee to the Spanish Netherlands. The impact of this victory won the support of Portugal and Savoy. Later, the Battle of Ramillies delivered the Low Countries to the Allies, and the Battle of Turin forced Louis to evacuate Italy, leaving it open to Allied forces. Marlborough and Eugene met again at the Battle of Oudenarde, which enabled them to invade France.
