Scarce Italian language battle plan of the Battle of Krefeld, fought in Krefeld, present-day North Rhine-Westphalia on June 23, 1758, during the Seven Years War.
The Hanoverian army led by Ferdinand, brother of the duke of Brunswick, had driven the French led by the Comte de Clermont back across the Rhine. The Battle of Rheinberg fought on June 12, 1758, had proved indecisive. Clermont, who had recently replaced the Duc de Richelieu in command of the French army, was attempting to stem Ferdinand's advance. He chose a defensive line on the south side of a walled canal running roughly east and west. Thus the walled canal constituted a sort of natural fortification that Clermont thought would be easy to defend.
The allied Prussian, British and Hanoverian troops led by the Duke of Brunswick seized the initiative attacking the entrenched defensive French forces. After feigning an attack against Clermont's own right flank, Ferdinand executed a wide flanking march, crossing the canal out of sight of the French and emerging from a wooded area on Clermont's left flank. Clermont, who had just sat down for a midday meal, was late in sending reinforcements and, as a result, his left flank was crushed.
The Comte de Gisors, the popular, charismatic, only child of the French minister of war, the Duc de Belle-Isle, was mortally wounded while charging at the head of the French Carabiniers. The Comte de St. Germain, who commanded the French left wing, was nevertheless able to put together a sufficient defense to prevent a complete rout, and the French army retired from the field in relatively good order.
The Erbprinz, son of the Duke of Brunswick, who would later die of wounds received at the battle of Jena during the Napoleonic Wars, particularly distinguished himself commanding the allied flanking troops. Clermont asked to be relieved of his command after this defeat. He was succeeded in command by Marshal de Contades.
