The French commanders had made several catastrophic tactical errors during the battle: The entire French left wing (the troops under Burgundy and the large mass north of the Norken) was kept in reserve. They could easily have destroyed the weakened right wing of the Allied army. Had a concerted attack been carried out, with Vendôme attacking with his main body to envelop the Allied right flank, while Burgundy attacked with the left wing (before Overkirk and the rest of Argyll's troops arrived), the French army could have easily won. The decision of the Duc de Bourgogne to march personally into battle may have provided a welcome boost to French morale, but denied him for the rest of the battle the opportunity to command his troops, which proved disastrous when the Allies overwhelmed the French via a flanking manoeuvre. The French army had lost about fourteen to fifteen thousand soldiers overall (with about eight thousand of whom becoming prisoners-of-war) and twenty-five artillery guns, while the Allies lost roughly three thousand men.
