Frederick William raised a volunteer corps known as the Black Brunswickers, named for their black uniforms. This force fought against Napoleon's occupation of Germany, conducting guerrilla-style operations and later serving in the British army.
After Napoleon's defeat at Leipzig, Frederick William returned to Brunswick and reclaimed his duchy, which had been annexed to the Kingdom of Westphalia. He re-established the Duchy of Brunswick under his rule.
Frederick William was killed while leading his troops at the Battle of Quatre Bras, a preliminary engagement before Waterloo. His death made him a symbol of German resistance against Napoleon, and his corps continued to fight.
