Military History of France - Middle Ages

Middle Ages

Military history during this period paralleled the rise and eventual fall of the armored knight. Following Charlemagne, there was a great increase in the proportion of cavalry supplemented by improvement in armor: leather and steel, steel helmets, coats of mail, and even full armor added to the defensive capabilities of mounted forces. Cavalry eventually grew to be the most important component of armies from French territories, with the shock charge they provided becoming the standard tactic on the battlefield when it was invented in the 11th century. At the same time, the development of agricultural techniques allowed the nations of Western Europe to radically increase food production, facilitating the growth of a particularly large aristocracy under Capetian France. The rise of castles, which began in France during the 10th century, was partly caused by the inability of centralized authorities to control these emerging dukes and aristocrats. After campaigns designed for plundering, attacking and defending castles became the dominant feature of medieval warfare.

During the Crusades, there were in fact too many armored knights in France for the land to support. Some scholars believe that one of the driving forces behind the Crusades was an attempt by such landless knights to find land overseas, without causing the type of internecine warfare that would largely damage France's increasing military strength. However, such historiographical work on the Crusades is being challenged and rejected by a large part of the historical community. The ultimate motivation or motivations for any one individual are difficult to know, but regardless, nobles and knights from France generally formed very sizeable contingents of crusading expeditions. Crusaders were so predominantely French that the word "crusader" in the Arabic language is simply known as Al-Franj or "The Franks" and Old French became the lingua franca of the Kingdom of Jerusalem.

In the 11th century, French knights wore knee-length mail and carried long lances and swords. The Norman knights fielded at the Battle of Hastings were more than a match for English forces, and their victory simply cemented their power and influence. Between 1202 and 1343, France reduced England's holdings on the continent to a few small provinces through a series of conflicts including the Bouvines Campaign (1202-1214), the Saintonge War (1242) and the War of Saint-Sardos (1324). Improvements in armor over the centuries led to the establishment of plate armor by the 14th century, which was further developed more rigorously in the 15th century. However, by the late 14th century and the early 15th century, French military power declined during the first part of the Hundred Years' War. New weapons, including artillery, and tactics seemingly made the knight more of a sitting target than an effective battle force, but the often-praised longbowmen had little to do with the English success. Poor coordination or rough terrain led to bungled French assaults. The slaughter of knights at the Battle of Agincourt best exemplified this carnage. The French were able to field a much larger army of men-at-arms than their English counterparts, who had many longbowmen. Despite this, the French suffered about 6,000 casualties compared to a few hundred for the English because the narrow terrain prevented the tactical envelopments envisioned in recently discovered French plans for the battle. The French suffered a similar defeat at the Battle of the Golden Spurs against Flemish militia in 1302. When knights were allowed to effectively deploy, however, they could be more useful, as at Cassel in 1328 or, even more decisively, at Bouvines in 1214 and Patay in 1429.

Popular conceptions of the final stages of the Hundred Years War are often dominated by the exploits of Joan of Arc, but French resurgence was rooted in multiple factors. A major step was taken by King Charles VII, who created the Compagnies d'ordonnance—cavalry units with 20 companies of 600 men each—and launched the first standing army for a dynastic state in the Western world. The Compagnies gave the French a considerable edge in professionalism and discipline. Strong French counterattacks turned the tide of the war. The important victories of Orléans, Patay, Formigny and Castillon allowed the French to win back all English continental territories, except Calais, which was later captured by the French.
