The Battle of Wilhelmsthal (sometimes written as the Battle of Wilhelmstadt) was fought on 24 June 1762 during the Seven Years' War between the allied forces of Britain, Prussia, Hanover, Brunswick and Hesse under the command of the Duke of Brunswick against France. Once again, the French threatened Hanover, so the Allies manoeuvered around the French, surrounded the invasion force, and forced them to retreat. It was the last major action fought by Brunswick's force before the Peace of Paris brought an end to the war.
