An army raised by Archbishop Thurstan of York around a cart of consecrated banners broke David I of Scotland’s invasion on Cowton Moor near Northallerton on 22 August 1138 — and then lost the peace, because David kept Carlisle and his son gained Northumberland within eight months.
The Battle of the Standard, fought on 22 August 1138 on Cowton Moor about two miles north of Northallerton, was the largest clash between English and Scottish armies since the Norman Conquest, and it is named after a piece of equipment rather than a place. The English centre was a ship’s mast lashed upright to a four-wheeled cart, with a silver pyx holding the consecrated host at its head and the banners of the minsters of York, Beverley and Ripon hanging below. Richard, prior of Hexham, writing within a few years of the battle, preserved the verse that explains the name: dicitur a stando standardum, quod stetit illic — it is called a standard from standing, because it stood there.
The fighting lasted perhaps three hours and ended in a rout. The campaign did not. David I of Scotland regrouped at Carlisle with his army beaten but his position intact, kept Cumberland, and in April 1139 secured the Second Treaty of Durham, which handed his son Henry the earldom of Northumberland. The Standard was an English tactical victory and a Scottish strategic success, which is why it has never fitted comfortably into either country’s account of itself.
David I had sworn in 1127, with the rest of Henry I’s magnates, to accept the king’s daughter Matilda as his heir. When Henry died in December 1135 and Stephen of England took the throne instead, David invaded — for the oath, and for Northumberland. The claim was his son’s: Henry’s mother Maud was the daughter of Waltheof, the last English earl of Northumbria, and David had wanted the earldom since Henry I’s reign. The first campaign took Carlisle, Wark, Alnwick, Norham and Newcastle within weeks, and the First Treaty of Durham of February 1136 bought him off with Carlisle, Doncaster and the honour of Huntingdon for his son — everything except the earldom he had come for.
He came back for it twice in 1138, in January and in April, and then in the summer with the whole strength of the kingdom. The timing was deliberate: Robert of Gloucester had renounced his allegiance to Stephen that spring and the empress’s war was beginning, so the king had the south to hold and nothing to spare for Yorkshire. Richard of Hexham’s account of the Scottish advance — churches burned, captives driven north into slavery, children killed — is the most quoted passage on the campaign and the most carefully handled, because Richard was a canon of Hexham writing about the army that had plundered his own church, and his purpose was to explain why God had given the victory to the other side.
Thurstan, archbishop of York, was about seventy and too ill to take the field, but the army was his. He preached resistance to the Scots as work done for God, sent the parish clergy north with their crosses and banners, and had the device that named the battle raised on the moor: the mast of a ship, mounted on a four-wheeled cart, crowned with a silver pyx containing the consecrated host, with the banners of Saint Peter of York, Saint John of Beverley and Saint Wilfrid of Ripon hanging from a crosspiece. Henry of Huntingdon records that Ralph Nowell, the titular bishop of Orkney, addressed the army in the archbishop’s name and promised absolution to the fallen.
The cart was a borrowed idea. Italian communes fought around a carroccio — Milan’s stood at the centre of the Lombard League’s line at the Battle of Legnano in 1176 — and the English version worked the same way as a rallying point visible across a moor, with one difference that mattered to everyone present. The pyx at the masthead made the army’s centre an altar. Men who could not read a banner understood that they were standing in the presence of the sacrament, and that the men opposite had burned churches to get there. It was the cheapest and most effective thing Thurstan did.
David wanted his mailed knights in front, where armour would tell against the English spears. The Galwegians claimed the first line as their customary right and would not give it up. Ailred of Rievaulx reports the argument: a Scottish mormaer — Malise, earl of Strathearn, on the usual modern identification, though Ailred does not name him — demanded to know why the king listened to foreigners when no man in mail would go further that day than one who wore none, and Alan de Percy, a Norman in David’s service, told him it was a great word and one he could not make good. David gave way. Ailred wrote his account about 1153 for an audience that included David’s own court, and the speeches in it are compositions rather than transcripts; what they preserve is the fault line in the Scottish army, which is corroborated by what happened next.
The Scots formed in four lines: the Galwegians, then Prince Henry with the knights, the archers and the men of Cumbria and Teviotdale, then the men of Lothian with islanders and men of Lorne, and last the king with the men of Scotia and Moray and his household. The English stood in one dense body on the ridge, men-at-arms dismounted among the spearmen with archers between them and the horses held to the rear. That arrangement — knights on foot, stiffened with bowmen, waiting to be attacked — is the earliest well-recorded English use of the formation that would win the Battle of Dupplin Moor in 1332 and the Battle of Halidon Hill in 1333, and nobody at Northallerton knew they had invented anything.
The Galwegians attacked at first light with a triple war-shout and struck hard enough to force the front rank of spearmen back before the men-at-arms closed the gap. Then the archery began, and it decided the battle within the hour. Ailred’s image of what it did to unarmoured men has outlived every other sentence written about the day: like a hedgehog with its quills, so you would see a Galwegian bristling all round with arrows, and still brandishing his sword and rushing forward in blind fury to strike a foe. When Domnall and Ulgric fell, the column broke and ran back through the lines behind it.
Prince Henry saved the Scottish honour and nothing else. He charged with his knights, broke clean through the English left and scattered the horse-holders in the rear, then found no second line following him and had to cut his way out. On the other flank the men of Lothian gave way when their lord was killed by an arrow. David’s household formed around him and tried to hold the field; his companions put him on a horse and took him off it. The English did not pursue far — they were infantry, and their commanders knew what a broken army does to loose pursuers. Henry reached Carlisle on foot with a single knight beside him, and the survivors came in over the following days.
English losses were very light: Richard of Hexham names one knight killed. Scottish losses are impossible to fix. Richard says that more than ten thousand men were missing when David counted the survivors, and John of Worcester gives nearly ten thousand dead with about fifty of the king’s picked men taken prisoner. Both are figures from the winning side, arrived at by a method nobody records, and they should be read as a way of saying that the army was wrecked rather than as a count.
One detail does read like a count, and it is the most telling in the sources: of the roughly two hundred mailed knights in David’s army, nineteen came away still wearing their hauberks. The rest had thrown away the most expensive object they owned to run faster, or lost it to a scavenger on the moor. That single number says more about the state of the Scottish army on the evening of 22 August than the ten thousand does — and it is also a reminder that the men who fought here were not an army in any later sense, but a kingdom’s worth of lordships, each of which went home when its lord did.
