Richard Caton Woodville’s The Battle of Towton.

A Battle of the Somme on British soil? It happened on Palm Sunday, 1461: a day of fierce fighting in the mud that felled a generation, leaving a longer litany of the dead than any other engagement in the islands’ history – reputed in some contemporary reports to be between 19,000 – the same number killed or missing in France on July 1 1916 – and a staggering 38,000.

The battle of Towton, fought near a tiny village standing on the old road between Leeds and York, on the brink of the North York Moors, is far less known than many other medieval clashes such as Hastings or Bosworth. Many will never have heard of it.

But here, in a blizzard on an icy cold March 29 1461, the forces of the warring factions of Lancaster and York met in a planned pitched battle that soon descended into a mayhem known as the Bloody Meadow. It ran into dusk, and through the fields and byways far from the battlefield. To the few on either side that carried their weapon to the day’s end, the result was by no means clear. But York in fact prevailed and within a month (almost to the day), the towering figure of Duke Edward, who stood nearly six-feet-five-inches tall, had reached London and seized the English crown as Edward IV. The Lancastrian king, Henry VI, fled into exile.

Towton was not merely a bloody moment in military history. It was also a turning-point in the long struggle for the throne between these two dynasties whose rivalry has provided – since the 16th century – a compelling overture to the grand opera of the Tudor legend, from Shakespeare to the White Queen. But this summer, as national attention focuses on the 100th anniversary of The Battle of the Somme, we might also take the opportunity to recall a day in our history when total war tore up a landscape that was much closer to home.

An English Doomsday

First, the historian’s caveats. While we know a remarkable amount about this bloody day in Yorkshire more than 550 years ago, we do not have the benefits granted to historians of World War I. Towton left behind no battle plans, memoranda, maps, aerial photographs, nor – above all other in value – first-hand accounts of those who were there. We cannot be certain of the size of the forces on either side, nor of the numbers of their dead.

A death toll of 28,000 was reported as early as April 1461 in one of the circulating newssheets that were not uncommon in the 15th century – and was taken up by a number of the chroniclers writing in the months and years following. This was soon scaled up to nearly 40,000 – about 1% of England’s entire male population – by others, a figure which also came to be cemented in the accounts of some chroniclers.

This shift points to the absence of any authoritative recollection of the battle – but almost certainly the numbers were larger than were usually seen, even in the period’s biggest clashes. Recently, historians have curbed the claims but the latest estimate suggests that 40,000 men took to the field, and that casualties may have been closer to 10,000.

But as with the Somme, it is not just the roll-call, or death-toll, that matters, but also the scar which the battle cut across the collective psychology. Towton became a byword for the horrors of the battlefield. Just as July 1 1916 has become the template for the cultural representation of the 1914-18 war, so Towton pressed itself into the popular image of war in the 15th and 16th centuries.

When Sir Thomas Malory re-imagined King Arthur for the rising generation of literate layfolk at the beginning of the Tudor age, it was at Towton – or at least a battlefield very much like it – that he set the final fight-to-the-death between Arthur and Mordred (Morte d’Arthur, Book XXI, Chapter 4). Writing less than ten years after the Yorkist victory, Malory’s Arthurian battleground raged, like Towton, from first light until evening, and laid waste a generation:

… and thus they fought all the long day, and never stinted till the noble knights were laid to the cold earth and ever they fought still till it was near night, and by that time there was there an hundred thousand laid dead upon the ground.

Lions and lambs

In his history plays, Shakespeare also presents Towton as an expression of all the terrible pain of the years of struggle that lasted over a century, from Richard II to Henry VIII. He describes it in Henry VI, Part 3, Act 2, Scene 5:

O piteous spectacle! O bloody times! While lions war and battle for their dens, poor harmless lambs abide their enmity. Weep, wretched man, I’ll aid thee tear for tear.

Both the Somme and Towton saw a generation fall. But while it was a young, volunteer army of “Pals” that was annihilated in 1916, osteo-analysis suggests that Towton was fought by grizzled older veterans. But in the small society of the 15th century, this was no less of a demographic shock. Most would have protected and provided for households. Their loss on such a scale would have been devastating for communities. And the slaughter went on and on. The Lancastrians were not only defeated, they were hunted down with a determination to see them, if not wiped out, then diminished to the point of no return.

For its time, this was also warfare on an unprecedented scale. There was no be no surrender, no prisoners. The armies were strafed with vast volleys of arrows, and new and, in a certain sense, industrial technologies were deployed, just as they were at the Somme. Recent archaeology confirmed the presence of handguns on the battlefield, evidently devastating if not quite in the same league as the German’s Maschinengewehr 08 in 1916.

These firearm fragments are among the earliest known to have been in used in northern European warfare and perhaps the very first witnessed in England. Primitive in their casting, they presented as great a threat to the man that fired them as to their target. Surely these new arrivals would have added considerably to the horror.

Fragments of the past

Towton is a rare example in England of a site largely spared from major development, and vital clues to its violent past remain. In the past 20 years, archaeological excavations have not only extended our understanding of the events of that day but of medieval English society in general.

The same is true of the Somme. That battlefield has a global significance as a place of commemoration and reconciliation, especially as Word War I passes out of even secondhand memory. But it also has significance as a site for “live” research. Its ploughed fields and pastures are still offering up new discoveries which likewise can carry us back not only to the last moments of those lost regiments but also to the lost world they left behind them, of Late Victorian and Edwardian Britain.

It is essential that these battlefields continue to hold our attention. For not only do they deepen our understanding of the experience and mechanics of war, they can also broaden our understanding of the societies from which such terrible conflict springs.
