Field Marshal Lord Frederick Cavendish (August 1729 – 21 October 1803) was a British Army officer and Whig politician. After serving as an aide-de-camp to the Duke of Cumberland in Germany during the early stages of the Seven Years' War, he served under Charles Spencer, 3rd Duke of Marlborough in the raid on St Malo and then took part in the raid on Cherbourg. Cavendish commanded the rear-guard during the re-embarkation following the disastrous battle of Saint Cast and was taken prisoner. After his release, Prince Ferdinand of Brunswick gave him command of a brigade of chasseurs which he led to victory at the Battle of Wilhelmsthal in June 1762.
