This is by far the most celebrated study of the Battle of Fontenoy and is an essential study for the campaign. Fontenoy was the bloodiest battle in Western Europe since Malplaquet in 1709, with French losses around 7,000 or 8,000 killed and wounded those of the Allies somewhere between 8,000 to 12,000, including prisoners. Victory restored French battlefield pre-eminence in Europe, although the best of the Allied infantry remained superior to their opponents.

Cumberland performed poorly as a commander, ignoring advice from his more experienced subordinates, failing to ensure the Bois de Barry was properly cleared and issuing Ingoldsby with conflicting orders. Although praised for his courage, the inactivity of the Allied cavalry was partly due to his participation in the infantry attack, and loss of strategic oversight. Ligonier and others viewed Fontenoy as a 'defeat snatched from the jaws of victory' and although understandable for a 24 year old in his first major engagement, the same faults were apparent at the Battle of Lauffeld in 1747.
