The Welsh Revolt, 1400–1415
On
16 September 1400, Owain acted, and was proclaimed Prince of Wales by a small band of followers which included his eldest son, his brothers-in-law, and the Dean of St. Asaph. This was a revolutionary statement in itself. Owain’s men quickly spread through north-east Wales. By
September 19, the De Grey stronghold of
Ruthin Castle was attacked and almost destroyed.
Denbigh, Rhuddlan, Flint, Hawarden, and
Holt followed quickly afterward. On
22 September the town of
Oswestry was so badly damaged by Owain's raid that it had to be re-chartered. By the 24th Owain was moving south attacking Powis Castle and sacking
Welshpool. Simultaneously, the Tudor brothers from
Anglesey launched a
guerrilla war against the English. The Tudors were a prominent Anglesey family who were closely associated with King Richard.
Gwilym Tudur and
Rhys ap Tudur had been Captains of Welsh archers in Richard's campaigns in Ireland. They quickly swore allegiance to their cousin, Owain Glyndŵr.
King Henry IV, on his way north to invade Scotland, turned his army around and by
26 September he was in
Shrewsbury ready to invade Wales. In a lightning campaign, Henry led his army around North Wales. He was harassed constantly by bad weather and the attacks of Welsh guerrillas. By
October 15, he was back in Shrewsbury with little to show for his efforts.
In 1401, the revolt began to spread. The whole of northern and central Wales went over to Owain. Multiple attacks were recorded on English towns, castles, and manors throughout the North. Even in the south in
Brecon and
Gwent reports began to come in of banditry and lawlessness by groups calling themselves the
Plant Owain – the Children of Owain. King Henry IV appointed
Henry Percy – the famous ‘Hotspur’, legendary warrior son of the powerful
Earl of Northumberland – to bring the country to order. Hotspur issued an amnesty in March which applied to all rebels with the exception of Owain and his cousins, Rhys and Gwilym, sons of
Tudur ap Gronw of Penmynydd, (forefather of
King Henry VII). Most of the country was mightily relieved and agreed to pay all the usual taxes, but the Tudors knew that they needed a bargaining chip if they were to lift the dire threat hanging over them. They coolly decided to capture
Edward I’s great castle at
Conwy. Although the garrison amounted to just fifteen men-at-arms and sixty archers, it was well stocked and easily reinforced from the sea; and in any case, the Tudors only had forty men. They needed a cunning plan. On Good Friday, which also happened to be
1 April – All Fool’s Day – all but five of the garrison were in the little church in the town when a carpenter appeared at the castle gate, who according to
Adam of Usk’s Chronicon, ‘feigned to come for his accustomed work’. Once inside, the Welsh chippy attacked the two guards and threw open the gate to allow the gang to rush in. Although Hotspur arrived from
Denbigh with 120 men-at-arms and 300 archers, he knew it would take a great deal more to get inside so formidable a fortress and, forced to negotiate, he finally gave the Tudors their Pardon.
Owain also scored his first major victory in the field. In June, at
Mynydd Hyddgen on
Pumlumon. Owain and his army of four hundred were camped at the bottom of the Hyddgen Valley when fifteen hundred English and Flemish settlers from
Pembrokeshire charged down on them. Owain rallied his army and fought back, killing 200 and making prisoners of the rest. The situation was sufficiently serious for the King to assemble another punitive expedition. This time he attacked through central Wales. From
Shrewsbury and
Hereford Castle, Henry IV's forces drove through
Powys toward the
Strata Florida Abbey. The
Cistercian house was known to be sympathetic towards Owain and Henry intended to remind them of their loyalties and prevent the revolt from spreading any further south. After terrible weather and constant harassment by the Plant Owain he reached
Strata Florida. Henry was in no mood to be merciful. After a two-day drinking session, his army partially destroyed the abbey and executed monks suspected of pro-Owain loyalties. However, he failed to engage Owain's forces in any large numbers.
Plant Owain harassed him and engaged in hit-and-run tactics on his supply chain but refused to fight in the open. Henry's army was forced to retreat. As he did so the weather turned. The army was nearly washed away in floods and Henry, sleeping in his armour, almost died when his tent was blown down. Wet, starving, and dejected, they returned to
Hereford Castle with nothing to claim for their efforts.
The English saw that if the revolt prospered it would inevitably attract disaffected supporters of the deposed King Richard. They were concerned about the potential for disaffection in
Cheshire and were increasingly worried about the news from North Wales. Hotspur complained that he was not receiving sufficient support from the King and that the repressive policy of Henry was only encouraging revolt. He argued that negotiation and compromise could persuade Owain to end his revolt. In fact, as early as 1401, Hotspur may have been in secret negotiations with Owain and other leaders of the revolt to attempt to negotiate a settlement. The core Lancastrian supporters would have none of this. They struck back with anti-Welsh legislation designed to establish English dominance in Wales. The laws actually codified common practices that had been at work in Wales and along the Marches for many years. The laws included prohibiting any Welshman from buying land in England, from holding any senior public office in Wales, from bearing arms, from holding any castle or defending any house, no Welsh child was to be educated or apprenticed to any trade, no Englishman could be convicted in any suit brought by a Welshman, Welshmen were to be severely penalised when marrying an Englishwoman, any Englishman marrying a Welshwoman was disenfranchised and all public assembly was forbidden. These laws sent a message to any of those who were wavering that the English viewed all the Welsh with equal suspicion. Many Welshmen who had tried to further their careers in English service now felt pushed into the rebellion as the middle ground between Owain and Henry disappeared.
In the same year, 1402, Owain captured his arch enemy, Reynald or
Reginald Grey, 3rd Baron Grey de Ruthyn in an ambush in January at
Ruthin. He was to hold him for a year until he received a substantial ransom from King Henry. Paying back this debt effectively ruined de Grey financially. In June 1402 Owain's forces encountered an army led by Sir
Edmund Mortimer, the uncle of the
Earl of March, at
Bryn Glas in central Wales.
Mortimer's army was badly defeated and Mortimer was captured. It is reported that the Welsh women following Owain’s army, killed the wounded English soldiers and mutilated the bodies of the dead, supposedly in revenge for plundering and rape by the English soldiery the previous year. Glyndŵr offered to release Mortimer for a large ransom but, in sharp contrast to his attitude to de Grey, Henry IV refused to pay. Mortimer could be said to have had a greater claim to the English throne than himself so his speedy release was not an option. In response, Sir Edmund negotiated an alliance with Owain and married one of Owain's daughters,
Catrin.
It is also in 1402, that mention of the
French and
Bretons helping Owain were first heard. The French were certainly hoping to use Wales as they had used Scotland as a base from which to fight the English. French
privateers began to attack English ships in the
Irish Sea and provide weapons to the Welsh. French and Breton
freebooters were also active in Owain's attacks.
