Answer:
True
Step-by-step explanation:
Ethnic Germans served on both sides of the American Revolutionary War. Many, notably rented auxiliary troops from Germanic states such as the Landgraviate of Hessen-Kassel, supported the Loyalist cause and served as allies of the Kingdom of Great Britain, whose King George III was also the Elector of Hanover.
American rebel agitators misrepresented such troops as mercenaries to fuel propaganda against the British Crown. Even American historians followed suit, in spite of Colonial-era jurists drawing a distinction between auxiliaries and mercenaries, with auxiliaries serving their prince when sent to the aid of another prince, and mercenaries serving a foreign prince as individuals. By this distinction the troops which served in the American Revolution were auxiliaries.
Other German individuals came to assist the American rebels, but most who did so were already colonists.
