Composition and Command of the Medieval Army

An army with different fighting roles

Between c1250 and c1500, English armies fought in conflicts with Wales, Scotland and France, as well as in civil wars. These armies brought together soldiers with different equipment and skills. Understanding their composition means considering both what soldiers did in battle and which groups in society supplied them.

The main distinction was between soldiers fighting on foot and those fighting on horseback. Infantry included close-combat foot soldiers and specialist missile troops such as archers. Mounted knights were an expensive, prestigious part of the army, but they depended on other soldiers rather than fighting battles alone.

Infantry: holding ground and fighting at close quarters

Ordinary infantry came largely from the lower ranks of society, including the peasantry. Their equipment was generally cheaper and less protective than that of wealthy knights. A foot soldier might have a simple helmet and leather protection rather than extensive metal armour.

Infantry helped hold defensive positions and fought enemy soldiers at close quarters using weapons such as spears, swords and daggers. Groups of foot soldiers holding their ground with spears could make it difficult for horsemen to break through. Their effectiveness therefore depended on remaining together: individual soldiers were much more vulnerable if their formation broke apart.

Infantry provided the army with men who could occupy and defend ground while other troops attacked from a distance or on horseback.

Archers: attacking from a distance

Archers were specialist foot soldiers who used bows; other missile troops used crossbows. Unlike close-combat infantry, they could attack enemies before the two sides came into direct contact.

Their role was to weaken and disrupt an opposing force. Shooting at approaching soldiers could cause casualties and make an attack harder to organise. This supported the work of other troops: an enemy weakened by missile fire could be easier for close-combat infantry or mounted knights to defeat.

The important distinction is between fighting on foot and fighting at close quarters. Archers were infantry, but their main task was to attack from a distance.

Mounted knights: wealth, training and striking power

Knights usually came from the gentry and nobility, the wealthier landowning groups. A fighting horse, armour and weapons were costly, and using them effectively required considerable training. Young men preparing for knighthood commonly trained from childhood, first as pages and then as squires assisting established knights.

A mounted knight carried weapons such as a lance and sword and wore a protective helmet and metal armour. Mail armour consisted of linked iron rings; plate armour became more common from the fourteenth century. Equipment therefore changed across this period rather than remaining identical for 250 years.

In battle, a mounted charge used the horse’s speed and the knight’s weapons to try to break enemy ranks. Its impact could frighten soldiers as well as injure them. Once an enemy force began to flee, mounted troops could pursue it and make regrouping more difficult. These roles were different from the infantry’s task of holding ground.

Why social position shaped command

Medieval society was unequal, and military authority reflected this social hierarchy. The monarch held ultimate authority. Powerful lords supplied and commanded troops, while wealthy knights occupied a higher social position than ordinary foot soldiers.

The feudal system connected landholding with military obligations. Lords held land from the monarch in return for service, including providing soldiers when required. Relationships between landholders and their followers helped turn royal demands for troops into an army.

Wealth affected both leadership and equipment. A lord had the resources and followers needed to organise a force; a wealthy knight could afford horses, armour and training that were beyond the means of most peasants. Social position therefore strongly influenced who commanded and how people served. This did not mean that every noble was a capable commander: inherited status and military ability were not the same thing.

Changing recruitment, continuing social differences

Feudal obligations were not the only way to obtain soldiers. During this period, rulers increasingly used paid soldiers, including mercenaries, rather than relying entirely on service owed through landholding. Some knights also fought for payment.

This distinction matters: how a soldier was recruited was not the same as what that soldier did in battle. Payment could change the relationship between a ruler and his troops without removing the differences between archers, close-combat infantry and mounted knights. Wealthy landowners also continued to have important advantages in equipment and command.

Who fought?

• Close-combat infantry: mainly lower-status foot soldiers; held ground and fought with weapons such as spears and swords.
• Archers: specialist infantry; attacked from a distance to weaken and disrupt enemies.
• Mounted knights: usually wealthy gentry or nobles; well equipped and trained for charges and pursuit.

Why did social status matter?

• Monarch: ultimate authority.
• Lords: supplied and commanded troops.
• Landholding: brought military obligations under the feudal system.
• Wealth: paid for horses, armour, weapons and training.
• High status supported access to command; it did not guarantee competence.

What changed across c1250–c1500?

Paid soldiers became increasingly important alongside feudal service. Recruitment changed, but distinctions in fighting roles and the advantages of wealthy commanders remained.
