After British troops launched an ill-fated invasion of Walcheren in the Walcheren Campaign of 1809, Napoléon lost patience with his hesitant brother and decided to make Holland an integral part of France. After annexing the southern provinces of Holland into the Empire, he forced King Louis to abdicate in 1810. Louis' son, Napoléon Louis Bonaparte, reigned for a week as "Louis II" before Napoléon annexed the rest of the kingdom into the French Empire. During that period Queen Hortense acted as Regent of the Kingdom.
