The English army that disembarked in France in 1346 to win its astonishing victory at Crécy was arguably the most formidable military machine in Europe. Disciplined, tactically sophisticated, and hardened by decades of conflict, it was a force defined by its professional core of men-at-arms and, most famously, the massed ranks of its longbowmen. Yet, this army was not born in the fields of northern France. Its sinews were forged and its character was tempered half a century earlier, in the mountains of Wales and across the rain-swept borderlands of Scotland, under the relentless pressure of one of England’s most formidable, and controversial, monarchs: Edward I.
When Edward ascended to the throne in 1272, he inherited a military system that was fundamentally archaic. The Anglo-Norman concept of the army was rooted in obligation, not profession. It was a projection of the tenurial structure of the kingdom, enshrined in documents like the Domesday Book of 1086, which meticulously recorded the lands held by tenants-in-chief from the king. In return for these lands, a baron owed the king servitium debitum—the ‘service owed’—which typically meant providing a quota of armoured, mounted knights for a period of forty days a year.
This system, which had served the Normans and early Plantagenets, was creaking under the strain of the thirteenth century. The forty-day limit was crippling for sustained campaigns. The quality and enthusiasm of the feudal levy could be suspect, and endless legalistic arguments erupted over the precise nature of the service owed. Monarchs like Henry II and John had sought to circumvent these limitations by accepting ‘scutage’ or shield-money in lieu of service, using the funds to hire mercenaries. Yet this was an ad-hoc solution. What Edward’s reign would witness was the systematic replacement of an army of obligation with an army of organisation—a transition from a feudal host to a state-managed military force. His great wars in Wales and Scotland were not merely campaigns of conquest; they were the anvil upon which this new English army was hammered into shape.
The Feudal Inheritance: An Army of Obligation
To understand the scale of Edward’s achievement, we must first appreciate the instrument he inherited. The traditional English army was a composite force. At its heart was the feudal levy: the great magnates of the realm—men like the Earl of Lincoln or the Bishop of Durham—leading their household retinues and the knights who held land from them. For a baron in Lincolnshire, whose ancestor may have been granted the lordship of Brattleby for service to William the Conqueror, the summons to war was a personal call from his own lord, the king.
The limitations were profound. The forty-day service began when the army mustered, not when it reached the war zone, making long-distance campaigns impractical. Moreover, the nature of knightly service itself was changing. By the late thirteenth century, the sub-division of estates meant that many landholders who owed the service of a full knight actually held only a fraction of a ‘knight’s fee’, leading to complex arrangements for sharing the cost or providing a substitute.
Beyond the feudal cavalry, the monarch could call upon the shire levies or fyrd, an Anglo-Saxon legacy compelling all free men to bear arms for local defence. While a potential source of massed infantry, the fyrd was poorly equipped, largely untrained, and legally bound to serve only within its own county, except in the gravest of national emergencies.
The result was an army ill-suited to the kind of warfare Edward planned. To conquer Wales, a land of mountains and fortresses, and to subdue Scotland, a vast and hostile kingdom, would require armies that could remain in the field for months, even years. It would demand huge numbers of specialised infantry, particularly archers, and a logistical train of unprecedented scale and complexity. The old feudal system could not provide this. A new model was needed, and the Welsh wars would be its first, brutal test.
The Welsh Crucible: Strategy, Logistics, and Manpower (1277-1283)
Edward’s campaigns against Llywelyn ap Gruffudd, Prince of Wales, in 1277 and 1282-83, were masterpieces of strategic and administrative planning that fundamentally reshaped the English military. Edward, a veteran of the brutal civil wars of his father’s reign and a seasoned crusader, understood that victory in the rugged terrain of Gwynedd would depend less on glorious cavalry charges and more on logistics, engineering, and overwhelming numbers.
His first innovation was logistical. Edward’s administration, particularly the clerks of the royal Wardrobe, which evolved into a de facto ministry of war, organised a vast supply chain. Sheriffs across England were commanded to purchase huge quantities of grain, oats, cheese, and wine—a process known as purveyance. The fertile plains of Lincolnshire were a key source for these supplies, which were transported via coastal shipping to depots established along the North Wales coast at Chester and Flint. This allowed English armies to operate deep within hostile territory, independent of local foraging, slowly strangling Welsh resistance.
The second innovation lay in manpower. While Edward did issue the traditional feudal summons in 1277, its response was lukewarm. Crucially, he augmented it with a far more effective system: paid service. He entered into formal contracts, or indentures, with his leading magnates and knights. These agreements specified the number of men they would bring, the rate of pay, and the duration of service. This created a reliable, professional core of heavy cavalry—the men-at-arms—who served not for a fleeting forty days but for as long as the king’s wages were forthcoming.
Even more revolutionary was the recruitment of infantry. Edward and his officials revived and systematised the ‘commission of array’. Commissioners, typically trusted local knights, were sent to every county with orders to select—or ‘array’—a specified number of able-bodied foot soldiers. Crucially, these men were to be paid. A foot archer typically received 2 pence a day, a significant sum for a peasant labourer.
The Welsh wars saw the first large-scale, centrally paid English infantry armies. In the 1282 campaign, records show Edward raising over 20,000 infantrymen. They were a diverse force. Thousands of archers were recruited from the Welsh Marches and the royal forests. Woodcutters and pioneers were levied to clear paths through the dense Welsh forests, and miners from the Forest of Dean were brought in to undermine the walls of Welsh castles.
This new army was deployed in a methodical, multi-pronged advance, supported by the third pillar of Edward’s strategy: engineering. Under the direction of the Savoyard genius Master James of St. George, a chain of colossal stone castles—the ‘Iron Ring’—was constructed at strategic points like Flint, Rhuddlan, Conwy, and Caernarfon. These were not mere military outposts; they were statements of permanent conquest, designed to be held by professional, paid garrisons year-round. They were royal administrative centres and colonial settlements, symbols of an English authority that was there to stay. The Welsh wars thus necessitated the creation of a standing army in microcosm, forcing the Crown to develop the administrative and financial structures to pay, feed, and control soldiers on a permanent basis.
The Lincolnshire Contribution: From the Wapentakes to War
For the lords and common men of Lincolnshire, the king’s great wars were not distant events. The county was deeply enmeshed in the national military effort, providing men, money, and materials on a scale that transformed the relationship between the locality and the state.
The most powerful magnate in the region was Henry de Lacy, 3rd Earl of Lincoln. A close friend and utterly loyal commander of Edward I, de Lacy was a central figure in the Welsh conflict, leading a major contingent of the army in 1282. His power base at Lincoln Castle and his vast estates across the county made him the king’s key agent in the region. When royal commissioners of array arrived in Lincolnshire, they would have worked with de Lacy’s bailiffs to select the required men from his manors—which included lands near Brattleby.
The surviving records, particularly the Calendars of Patent and Close Rolls, allow us to glimpse this process in action. In May 1282, for example, a commission was issued to two knights, Walter de la Lynde and Walter de Stirchesle, to "choose 1,000 footmen" from the counties of Lincolnshire and Rutland. These men were ordered to muster at Lincoln on a specific date, before marching to the assembly point for the Welsh campaign at Chester. For a man from a small village like Brattleby, which according to Domesday Book was a modest settlement in the Lawress Wapentake, to be chosen by the commissioners would have been a life-altering event. It meant leaving the familiar rhythms of the agricultural year for the brutal, unfamiliar world of a military campaign hundreds of miles away.
Their service was not free. The community was often expected to pay for their arms and their travel to the muster point, a burden that frequently fell on the local hundred or wapentake. The financial strain was immense. Edward’s relentless demands for taxation to fund his wars were a constant source of friction. The wool trade, in which Lincolnshire was a leading player, was a primary target. The infamous ‘Maltolt’ of 1297, a punitive tax of 40 shillings on each sack of wool exported, hit the county’s monastic houses and secular landlords hard, prompting widespread resistance that forced Edward to reconfirm Magna Carta.
Lincoln itself served as a crucial hub. Its strategic position, linked by the River Witham to the coast and by the Roman-era Fossdyke to the Trent, made it an important centre for collecting and dispatching supplies. The city’s looms produced cloth for uniforms, and its merchants and guilds were frequently pressed for loans. Earlier in the century, the city had been the site of a decisive battle in 1217 that had secured the Plantagenet throne for Edward’s grandfather, Henry III. Now, under Edward, it was less a battlefield and more a vital cog in a national war machine, its resources systematically harnessed for campaigns on the kingdom’s frontiers.
The Scottish Anvil: Tactical Integration and the Longbow’s Ascendancy
If the Welsh wars created the administrative framework for a professional army, the long and gruelling Scottish wars (1296-1307) perfected its tactical employment. The challenge in Scotland was different. It was a larger kingdom with a proud martial tradition, capable of fielding its own formidable armies. The Scottish infantry, drawn up in dense circles of spearmen known as ‘schiltrons’, proved a difficult nut for English heavy cavalry to crack.
Edward’s response was to refine the ‘combined arms’ approach he had trialled in Wales. The classic demonstration of this new tactical doctrine came at the Battle of Falkirk on 22 July 1298. Having been provoked by William Wallace’s victory at Stirling Bridge the previous year, Edward invaded Scotland at the head of a massive army, including a huge contingent of infantry levied through commissions of array from across England and Wales. Records show orders being issued for some 12,500 infantry, including a significant force of archers from Cheshire and Lancashire. Henry de Lacy, Earl of Lincoln, once again commanded one of the main divisions, or ‘battles’, of the English army.
At Falkirk, the English cavalry, eager for glory, charged the Scottish schiltrons but were repulsed by the hedge of spears, suffering heavy losses. It was a tactical impasse. Had this been a traditional feudal army, morale might have collapsed. But Edward had another weapon. He is said to have cursed the impatience of his knights, before calmly ordering his infantry forward. He deployed his archers, particularly the Welsh longbowmen, in the gaps between his cavalry formations.
What followed was a revolution in medieval warfare. The archers unleashed a devastating storm of arrows—a ‘rain of death’ as one chronicler described it—into the tightly packed, static Scottish ranks. The schiltrons, with no answer to this sustained, long-range assault, began to waver and break. The arrows tore great gaps in their formations, and only then did Edward release his men-at-arms. The cavalry now charged into the disordered and demoralised spearmen, shattering them completely.
Falkirk was a brutal but vital lesson. It demonstrated that heavily armoured knights were no longer the sole arbiters of the battlefield. Victory now depended on the careful coordination of cavalry and infantry, with the longbow acting as the can-opener that broke enemy formations before the cavalry delivered the killing blow. This became the classic English battle tactic, one that would be repeated with even more devastating effect at Crécy and Agincourt. The humble foot soldier, the anonymous man from Lincolnshire or Cheshire paid his 2 pence a day, had become the kingdom’s primary war-winner.
The Anatomy of Edward’s New Model Army
By the end of his reign in 1307, Edward I had fundamentally and irrevocably professionalised the English military. The army he bequeathed to his son was a radically different entity from the one he had inherited. Its key components were clear:
1. A Professional Core: The heart of the army was no longer the reluctant feudal levy, but a paid, contracted force of men-at-arms. These were full-time soldiers, forming the king’s household retinue and the retinues of his great magnates, serving year-round for wages under formal indenture.
2. Massed Paid Infantry: The system of commissions of array allowed the crown to raise tens of thousands of paid foot soldiers for specific campaigns. While not a permanent standing army, the system for raising and paying them was permanent and highly organised.
3. The Dominance of the Longbow: The Welsh and Scottish wars established the longbow as the supreme infantry weapon. Edward’s administration actively encouraged archery practice, and the longbowman became a specialised and highly valued type of soldier.
4. Centralised Administration: The royal Wardrobe had become a sophisticated and bureaucratic war office, with its own clerks and officials responsible for pay, supply, and equipment. The survival of detailed Wardrobe accounts and pay rolls from this period is a testament to their meticulous record-keeping.
5. A Strategy of Conquest: Edward’s strategy was not one of raiding and plunder, but of permanent occupation, exemplified by the Welsh castles and the network of English-held fortifications in southern Scotland. This required garrisons and a logistical system capable of sustaining a year-round military presence.
This transformation was not without cost. The financial strain it placed on the realm was immense, leading to constitutional crises and bitter disputes with his barons and the Church. The human cost, for the thousands of English, Welsh, and Irish infantry who fought and died in these campaigns, was incalculable. Yet the result was undeniable. Edward I had taken an archaic, obligation-based military system and reforged it on the anvil of war. He created a national, state-funded, and professionally organised army that would dominate the battlefields of Western Europe for the next century, securing England’s reputation as a major military power. The road to Crécy began in the mountains of Gwynedd and the lowlands of Scotland, and it was paved by the administrative genius and ruthless will of Edward Plantagenet.
