Marquis de Castries Westphalia, Hesse and Lower Saxony Electoral Saxony Brandenburg Silesia East Prussia Pomerania Iberian Peninsula Naval Operations The Battle of Kloster Kampen (or Kloster Kamp, or Campen) was a tactical French victory over a British and allied army in the Seven Years' War.

The battle began in the middle of the night when the army's vanguard drove the French out of Kloster Kampen convent and took the bridge over the canal.

The Marquis de Castries brought up his reserves and rallied the retreating regiments then launched a counter-offensive against the allied foot.

At the western end of the canal, Eliott led the three British cavalry regiments in a charge which disrupted the French advance and enabled the retreating allied foot to regain the North bank.

The Allied defeat caused disappointment in Britain where many had expected better news, following the large expansion of Frederick's army.
