The Hessians were German mercenaries, so they were Germans.
German mercenaries in the Revolutionary War were known as Hessians. They were the bulk of the soldiers defeated by Continental troops at the Battle of Trenton on the Delaware River.
the germans mercenaries hired to fight the american rebelswere known as?
They were Germans from the State of Hesse. Germany was not yet a single country, and each of the several states had their own alliances.
I think it was the "Hessians" [spelling?], who were Germans hired by the British to fight for them.
History records that "Hessians" were the German mercenaries who fought the colonists. However, they were not mercenaries in the modern sense. The term comes from soldiers in service to the state of Hesse-Cassel, which like Hanover was not yet part of a unified German state. To utilize the standing military forces, King George III paid a fee to his uncle, Frederick II, Landgrave of Hesse-Cassel. This was not the only time soldiers from German regions were used in the British Empire. More than 1/4 of about 24,000 of these soldiers died during the war. The term "Hessian mercenary" is somewhat of a generalization, as a number of the German-British soldiers fighting under King George III came from the German region of Hanover, which was a British holding at the time. King George III was descended from the House of Hanover, which was a royal German family, and many of the Germans who fought for him during the American Revolution were actually his legal subjects, meaning they weren't mercenaries at all. There is no doubt many German mercenaries, particularly from Hesse, also fought in support of the British Crown, but Germany was not a united country at that time in history, as much of it was known as the Holy Roman Empire, and different Germans had different allegiances. "Hessian mercenary" was more or less a general term that denoted all German mercenaries, be they from Hesse, Prussia, or any where else in the German speaking lands.
Germans
The French helped the Americans in the American Revolution while the Hessians (Germans) helped the British. Marquis de Lafayette was a French-aid to the colonists in the revolution, along with Bernardo de Galvez of Spain.
They fought both sides
The Hessians fought as a mercenary army.
King George III hired about 18,000 German mercenary soldiers called "Hessians" to augment British forces. The Americans were infuriated because the Germans were known for their brutal methods plus the Americans considered it to be a "family" war.
The Zweibrucken Regiment was a regiment of Germans that fought in the French Army during the American Revolutionary War. They helped the Americans defeat the British at the battle of Yorktown.
