Westphalia, Hesse and Lower Saxony Electoral Saxony Brandenburg Silesia East Prussia Pomerania Iberian Peninsula Naval Operations 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.

It was the last major action fought by Brunswick's force before the Peace of Paris brought an end to the war.

France had made a number of attempts to invade and overrun Hanover since 1757 in the hope of occupying the Electorate and using it as a bargaining counter to exchange for the return of French colonies captured by the British.

An attack on the French center held by Stainville's command was particularly effective, with one column engaging his front, another striking his rear, inflicting some 900 casualties[3] and forcing 2,700 to surrender.

The Anglo-German forces advanced and captured Cassel in November, but by then, the preliminaries of peace had been signed.
