Afterword

The term "Middle Ages," a phrase coined by Renaissance humanists, was originally intended as a pejorative, a label for what they perceived as a long, stagnant period between the glories of classical antiquity and their own "rebirth" of learning. This "in-between" era, roughly spanning a thousand years from the fall of the Western Roman Empire in the 5th century to the cusp of the modern period around the 15th century, has often been mischaracterized as the "Dark Ages." While it's true that the collapse of Roman authority in the West led to a period of significant upheaval—population decline, political fragmentation, and the loss of certain classical knowledge—to dismiss this entire millennium as a period of unenlightened stagnation is to overlook a dynamic and transformative era in human history, particularly in the realm of warfare.

This book, "Great Battles of the Middle Ages," seeks to illuminate this complex period through the lens of its most significant and decisive military engagements. The battles chosen for inclusion span the full breadth of the Middle Ages, from the late Roman Empire's desperate struggles against barbarian incursions to the twilight of the knightly ideal in the fires of the Hundred Years' War. They represent a journey through a constantly evolving military landscape, a world where the disciplined legions of Rome gave way to the mounted prowess of the feudal knight, and where the stone walls of castles, once seemingly impregnable, were ultimately humbled by the transformative power of gunpowder.

The chronological scope of this work, from the fall of Rome to the end of the Hundred Years' War, is not arbitrary. The end of the Western Roman Empire marked a fundamental shift in the political and military organization of Europe. The centralized, professional army of Rome was replaced by a mosaic of successor kingdoms, each with its own distinct military traditions. This led to a period of military experimentation and adaptation, as new threats and new technologies reshaped the art of war. The Hundred Years' War, in turn, serves as a fitting bookend to this era. The conflict witnessed the decline of the heavy cavalry's dominance and the rise of disciplined infantry and new missile weapons, most notably the English longbow. Furthermore, the increasing use of gunpowder weapons in the latter stages of the war signaled the dawn of a new age of warfare, one that would render the medieval castle and the armored knight increasingly obsolete.

The very nature of what constituted a "battle" in the Middle Ages is a central theme of this book. While popular imagination often conjures images of massive armies clashing in open fields, the reality was often quite different. Pitched battles were risky and often avoided by prudent commanders. Warfare in the Middle Ages was more commonly a protracted affair of sieges, raids, and skirmishes. The control of fortified places—castles and walled towns—was of paramount strategic importance. A successful siege could secure a territory more effectively and with less risk than a single, decisive battlefield victory. Indeed, it has been estimated that siege warfare constituted the vast majority of military operations during this period.

Nevertheless, the great field battles, when they did occur, were often pivotal moments that could alter the course of history. A "decisive battle" is one that resolves a major strategic issue, effectively ending one phase of a conflict and beginning another. The battles chronicled in this volume were chosen not merely for their scale or ferocity, but for their lasting impact. They are the engagements that led to the rise and fall of kingdoms, the forging of national identities, and the establishment of new political and social orders. From the Visigothic victory over the Romans at Adrianople, which heralded the beginning of the end for the Western Empire, to the French triumph at Castillon, which effectively ended the Hundred Years' War and the long and bloody chapter of English ambitions in France, each battle represents a turning point with far-reaching consequences.

The evolution of military technology is another critical thread that runs through this narrative. The early Middle Ages saw the rise of the mounted warrior as the dominant force on the battlefield. The introduction of the stirrup, a seemingly simple innovation, revolutionized cavalry tactics by allowing a rider to brace themselves and deliver a powerful, couched-lance charge. This, combined with advancements in armor and the breeding of powerful warhorses, gave the heavy cavalry of the High Middle Ages a formidable advantage.

However, the dominance of the knight was not absolute. The later Middle Ages witnessed a so-called "infantry revolution," where well-disciplined foot soldiers, armed with pikes, halberds, and other polearms, proved they could stand against and defeat mounted knights. The Swiss pikemen, in particular, became renowned for their disciplined formations and their ability to withstand cavalry charges. This shift was accompanied by the increasing prominence of missile weapons. The crossbow, a powerful and easy-to-use weapon, could penetrate most armor of the period. Even more devastating was the English longbow, which, in the hands of skilled archers, could unleash a veritable storm of arrows, as demonstrated with deadly effect at Crécy and Agincourt.

The final and most profound technological shift of the Middle Ages was the introduction of gunpowder. Initially crude and unreliable, early firearms and cannons had more of a psychological than a physical impact on the battlefield. However, as the technology improved, gunpowder weapons began to fundamentally alter the nature of warfare. Cannons could now batter down the walls of even the most formidable castles, rendering traditional fortifications obsolete and forever changing the calculus of siege warfare.

Underpinning all of these developments were the logistical realities of medieval warfare. In an age before modern supply trains, armies were largely expected to live off the land, foraging and looting as they went. This made the conduct of campaigns a challenging and often brutal affair, both for the soldiers and for the civilian populations in their path. The size and duration of military campaigns were often limited by the availability of food and other supplies. A commander's ability to manage the complex logistics of feeding and equipping an army was as crucial to success as their tactical acumen on the battlefield.

This book will delve into the details of these transformations, examining how each of the selected battles reflects the broader military, political, and social currents of its time. We will explore the strategies and tactics employed by the commanders, the weapons and armor of the soldiers, and the often-brutal realities of medieval combat. Through the stories of these great battles, we will gain a deeper understanding of the medieval world, a world of faith and fury, of chivalry and savagery, a world that, far from being a stagnant interlude, was a crucible in which the foundations of modern Europe were forged.

The road to Adrianople was paved with desperation, not glory. It was a path forced upon the Eastern Roman Emperor Valens by a crisis of his own administration's making. In the year 376, a great mass of Gothic people, primarily the Thervingi, appeared on the northern banks of the Danube River. They were not an invading army in the traditional sense, but rather refugees, a nation on the move, fleeing the westward expansion of the Huns, a nomadic people from the steppes of Central Asia whose martial prowess had struck terror into the hearts of all who stood in their path. The Goths, led by their chieftain Fritigern, petitioned Emperor Valens for permission to cross the river and settle within the comparative safety of the Roman Empire.

Valens, who at the time was occupied with matters on the Persian frontier, saw an opportunity. These Goths, he reasoned, could be a valuable source of manpower for the Roman army, a perennial concern for an empire with vast borders to defend. He granted their request, but with conditions. The Goths were to surrender their weapons and provide their children as hostages, to be raised and educated as Romans. In return, they were promised land and provisions. It was a standard Roman approach to managing barbarian peoples on their frontiers, a policy of controlled assimilation that had been employed with varying degrees of success for centuries.

However, the implementation of this policy was disastrously mishandled by the local Roman officials, Lupicinus and Maximus. Driven by greed and corruption, they exploited the vulnerable Goths, withholding the promised food supplies and enriching themselves at the refugees' expense. The situation quickly deteriorated. Starvation loomed, and the Goths, who had been allowed to keep their arms through either Roman negligence or bribery, grew increasingly restive. The breaking point came when Lupicinus, in a move of stunning incompetence, attempted to assassinate Fritigern and other Gothic leaders during a banquet at Marcianople. Fritigern escaped, and the simmering resentment of his people erupted into open revolt.

What had begun as a refugee crisis had now become a full-blown war. The Goths, now joined by other groups including the Greuthungi who had crossed the Danube without permission, began to raid and plunder the rich Roman province of Thrace. For two years, the Balkans were subjected to a brutal campaign of devastation. Small-scale Roman forces were unable to contain the Gothic rampage. The situation grew so dire that Valens was forced to conclude a hasty truce with the Persians and return to Constantinople in the spring of 378 to take command of the situation personally.

The political atmosphere in the capital was toxic. The citizens of Constantinople, their supply lines threatened and their countryside ravaged, were furious with Valens, blaming him for the crisis. The emperor, a man described as indecisive and insecure, took this criticism personally. His mood was not improved by the glowing reports arriving from the Western Roman Empire, where his young and popular nephew, the Emperor Gratian, was winning significant victories against Germanic tribes along the Rhine. This combination of public pressure and personal envy would prove to be a fatal cocktail, clouding Valens' judgment in the critical days to come.

Upon his arrival, Valens assembled a formidable army, drawing veteran units from his campaigns in the east. These were the elite troops of the Eastern Roman Empire, a balanced force of heavy infantry, archers, and cavalry. Estimates of the Roman army's strength vary, but it likely numbered between 20,000 and 30,000 men. After establishing his headquarters near Adrianople, Valens received word that Gratian was marching east with reinforcements to aid him. His senior officers, including the experienced general Victor, strongly advised him to wait for his nephew's arrival. A combined force, they argued, would ensure a decisive victory.

Fritigern, a shrewd and capable leader, understood the strategic situation perfectly. He knew that his best chance of success lay in defeating Valens' army before it could be reinforced. To this end, he employed a clever strategy of deception. Roman scouts reported the Gothic force to be a mere 10,000 strong, a significant underestimate that played directly into Valens' desire for a swift and glorious victory that he could claim for himself. It is likely that this intelligence was based only on Fritigern's Thervingi, with the Greuthungi cavalry, led by Alatheus and Saphrax, away on a foraging expedition.

Fritigern further played on Valens' impatience by sending a Christian priest as an envoy with offers of peace, while secretly urging the emperor in a private message to make a show of force to convince his own people to accept the terms. This was precisely what Valens wanted to hear. Convinced that the Goths were on the verge of collapse and eager to monopolize the glory of victory before Gratian's arrival, he made the fateful decision to march out and engage the Goths immediately. He dismissed the counsel of his more cautious generals and, at dawn on August 9, 378, led his army out of Adrianople.

The march to the Gothic camp, located about eight miles north of the city, was an ordeal in itself. The day was brutally hot, and the Roman soldiers, burdened by their heavy armor and equipment, marched over difficult and exposed terrain. They arrived before the Gothic position around two in the afternoon, already weary and dehydrated. The Goths had established a strong defensive position, their wagons formed into a circular laager, a mobile fortress, on a hilltop. Inside this wagon circle were their families and all their possessions.

As the Roman army began to deploy into battle formation, Fritigern continued his delaying tactics. He sent more envoys to negotiate, buying precious time for his absent cavalry to return. He also ordered his men to light grass fires, which, driven by the wind, sent thick smoke billowing into the faces of the already suffering Romans, further adding to their discomfort. Valens, despite his eagerness for battle, seems to have been willing to entertain the negotiations, perhaps still believing a surrender was imminent.

The battle, however, began not with a formal order, but with a breakdown in Roman discipline. A contingent of Roman cavalry, acting without orders, launched a premature and uncoordinated attack on the Gothic lines. This initial charge, though it pressed the Goths back towards their wagon circle, was ultimately repulsed. The engagement then became general as other Roman units were drawn into the fray. The Roman left wing advanced and made some progress, even reaching the wagons, but they were unsupported by the rest of the army and could not break through. The battle was devolving into a chaotic and piecemeal struggle, exactly the kind of fight that negated the Roman army's traditional strengths of discipline and cohesion.

It was at this critical moment that the decisive factor in the battle made its dramatic appearance. Descending "like a thunderbolt from the mountains," the Greuthungi and Alan cavalry under Alatheus and Saphrax, having returned from their foraging expedition, slammed into the Roman army's right flank. The impact was devastating. The Roman cavalry on that wing, which may have been caught out of position or already engaged, was shattered and routed from the field.

With the Roman flank exposed, the Gothic horsemen wheeled and began to envelop the Roman infantry. The Roman legions, already exhausted and disorganized, were now pressed from the front by Fritigern's infantry and attacked from the flank and rear by the victorious Gothic cavalry. The Roman lines began to collapse. The soldiers were packed so tightly together that they had no room to maneuver or effectively wield their weapons. Panic and confusion spread through the ranks.

What followed was not a battle, but a slaughter. The Roman army, trapped in the crushing embrace of the Gothic forces, was systematically destroyed. The historian Ammianus Marcellinus, our primary source for the battle, describes a scene of horrific carnage, with men slipping on blood-soaked ground and the plain covered with the corpses of the slain. He states that two-thirds of the Roman army perished, a loss of life comparable to the disastrous defeat at Cannae centuries earlier.

In the midst of this chaos, Emperor Valens was abandoned by his bodyguards. His final moments are uncertain. One account suggests he was struck by an arrow and, wounded, was carried to a nearby farmhouse which was then surrounded and burned by the Goths. Another version claims he dismounted and fought on foot among his soldiers until he was cut down, his body, stripped of its imperial insignia, never to be identified among the thousands of dead. Whatever the exact circumstances, the Emperor of the Eastern Roman Empire was killed on the field of battle. His body was never found.

The defeat at Adrianople was an unmitigated catastrophe for the Roman Empire. Along with the emperor, a host of high-ranking officers and veteran soldiers were killed, effectively wiping out the core of the Eastern field army. In the immediate aftermath, the victorious Goths attempted to take the city of Adrianople itself, where the imperial treasury was stored, but they lacked the siege equipment and expertise to overcome its walls and were repulsed.

Freed from the threat of a major Roman army, the Goths and their allies rampaged through the Balkans for the next four years, plundering and destroying at will. The shockwaves of the defeat were felt across the empire. It shattered the long-held myth of Roman invincibility and demonstrated that the "barbarian" peoples on their frontiers had become formidable military powers in their own right. The loss of a significant portion of its military manpower exacerbated an already severe recruitment crisis within the empire. The battle did not, in itself, cause the fall of the Western Roman Empire, but it marked a significant turning point, accelerating a process of military and political transformation that would ultimately lead to the end of Roman power in the West. The new emperor in the East, Theodosius I, would eventually be forced to make peace with the Goths in 382, allowing them to settle within the empire as autonomous allies, a precedent that would have profound consequences for the future. The disaster at Adrianople had shown that the old order was crumbling, and a new, more uncertain era was dawning.
