The Battle of Krefeld (sometimes referred to by its French name of Créfeld, and as Creveld) was fought at Krefeld near the Rhine on 23 June 1758 between a German army under Duke Ferdinand of Brunswick-Wolfenbüttel and a French army under Count Louis of Clermont during the Seven Years' War. As a result of this Ferdinand's victory, the British government eventually decided to reinforce him with a significant number of troops from the island.
By the time of the battle, the French army in Germany had deteriorated due to poor provisions, poor administration, and constant retreats; all this also had an impact on the soldiers' morale. Its presence there was marked by major defeats such as Krefeld, Rossbach in 1757, and Minden in 1759.
