English: at least 2,000 infantry and 20 cavalry (true extent unknown). Welsh: sources suggest an initial force of 7,000, though the reliability of this figure is questioned by Llinos Beverley Smith.
The Battle of Orewin Bridge (also known as the Battle of Irfon Bridge or the Battle of Builth) was a confrontation between an English force guided by Roger Lestrange and a Welsh force led by Prince Llywelyn ap Gruffudd. It was fought on 11 December 1282 near Builth Wells in mid-Wales. It was a decisive defeat for the Welsh and Llywelyn ap Gruffudd was killed, leading to the final defeat of the Welsh rebels by the armies of Edward I of England some months later.
The exact details of the confrontation, including the geographic setting and its scale, are heavily contested, both among contemporary chronicles and later scholars.
On 10 December 1277, the Treaty of Aberconwy was signed between Wales and England following an English invasion in the same year. It forced Llywelyn to pay an indemnity of 50,000 marks, allow Edward I to build castles at key points, and marry the English noblewoman Eleanor de Montfort. The treaty was deeply unpopular in Wales, leading to a general revolt throughout much of Wales five years later. Both Llywelyn and Edward I mobilized their armies to march on the other's territory while also opening negotiations. Edward suffered a setback at the Battle of Menai in November but remained intent on conquering Wales. Meanwhile, Llywelyn led a campaign throughout the southern districts of Wales. When English commander Roger Lestrange received news of Llywelyn's movements in Wales, he assembled an army to intercept him in the southern districts. His force numbered at least 2,000 infantry and 20 cavalry, but the true extent of his force is unknown.
On 11 December, Llywelyn moved south out of Gwerthrynion and into Builth. David Stephenson notes the role of the brothers Edmund, 2nd Baron Mortimer of Wigmore and Roger, 1st Baron Mortimer of Chirk in this action. They likely lured Llywelyn in on false promises of homage, though there is no definite proof of this. Their father, Roger, 1st Baron Mortimer of Wigmore, had recently died and his command has been handed over to Roger Lestrange. It is unlikely that Lestrange, in overall command, was present at Orewin Bridge.
Emma Cavell argues that noble wives likely played an important behind-the-scenes role in the lead-up to the confrontation. Women such as Maud Mortimer or Hawise Lestrange were part of the network of spies relied by upon men in tracking the movements of Llywelyn. Their authority as women came from key social networks they held as aristocratic ladies.
The details surrounding Llywelyn's death have been examined by a number of historians over the decades. For example, John Edward Morris, John Edward Lloyd, and David Stephenson primarily relied on the chronicle of Walter of Guisborough, also known as Walter of Hemingburgh.
The site of Battle of Orewin Bridge (1282) lies on Ludlow Rocks (Undifferentiated), bedrock that formed in the Ludlow. The rock here is mudstone, siltstone and sandstone.
The most striking and contested detail surrounding the battle is the killing of Llywelyn himself. According to Walter of Guisborough, an English soldier named Stephen de Frankton struck Llywelyn down without recognising him as he went to investigate sounds from the direction of the ford. Only after the blow was delivered did Stephen realise whom he had felled, and he returned specifically to finish the killing. The Hagnaby Chronicle offers a starker version still: Llywelyn fought in the main battle, was eventually left alone on the field with only a single servant, fled towards the woods, called out his true identity to his pursuers, and was executed regardless. Whichever account is closer to the truth, both agree that the last native Prince of Wales died on 11 December 1282, far from his stronghold in Gwynedd, in circumstances that bore the hallmarks of betrayal.
