The allied Prussian 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.
