The Most devastating Weapon in Medieval History! - Battle of Crug Mawr 1136 — Transcript
Full transcript
- 0:09It is the autumn of 1136, and for decades, Norman lords and their Welsh allies had expanded
- 0:15their control across the region, seizing lands, constructing castles, and steadily pushing native
- 0:21Welsh rulers into smaller territories. But in 1136, that expansion began to unravel. A rebellion
- 0:30had erupted across southern Wales. Norman castles were being attacked, soldiers ambushed, and Welsh
- 0:36princes who had once fought among themselves were beginning to unite against a common enemy.
- 0:43In response, a large Norman Flemish force was assembled and dispatched from South Wales to
- 0:49suppress the rebellion. The army was commanded by Robert Fitz Martin. Robert Fitz Stevens, Maurice
- 0:55Fitzgerald, and Steven, Constable of Cardigan. Medieval sources do not provide a reliable figure
- 1:02for the army's strength, and later estimates vary considerably, so claims of 10,000 to 12,000 men
- 1:10should be treated with caution. The force likely consisted primarily of infantry supported by
- 1:16Norman knights and mounted warriors. The Welsh forces, meanwhile, had gathered to meet this
- 1:23advancing army northeast of Cardigan. The precise location of the coming battle remains uncertain,
- 1:29but historians have traditionally associated it with a prominent ridge or hill near a farm known
- 1:35as Krug Mau, meaning great hill. The Welsh army was led by Owen Gwyneth and his brother Cadwalader
- 1:44Abg Griffith alongside Griffith Apprisath and other Welsh leaders who had joined the rebellion.
- 1:52Their army was probably smaller than the Norman Flemish force, although the exact numbers
- 1:57are unknown. The Welsh also lacked the heavily armored cavalry for which the Normans were famous.
- 2:04Instead, they relied heavily on their skilled Welsh longbowmen. Welsh archers had already earned
- 2:11a formidable reputation for their ability to fight from difficult terrain and deliver effective
- 2:16missile fire. Their importance would become increasingly apparent as the battle unfolded.
- 2:23The Normans, confident in the strength of their disciplined heavy infantry and heavily armed
- 2:29cavalry, stood patiently and allowed the enemy to come to them. They expected to crush what they
- 2:36regarded as a poorly equipped Welsh rebellion. But what they had in numbers and superior cavalry,
- 2:43they lacked in ranged troops. As reports suggest, they fielded no ranged units of any kind. The
- 2:51Welsh army finally faced the Norman Flemish force near Cardigan sometime in late September
- 2:58or October 1136. Both sides understood what was at stake. For the Welsh, victory could break Norman
- 3:08control over much of Western Wales and give the rebellion new momentum. For the Normans,
- 3:15defeat could jeopardize their entire position in Western Wales, threatening the castles, lands,
- 3:22and influence they had spent decades establishing. Neither side could afford to retreat. The Welsh
- 3:31prepared to defend their homeland. The Normans prepared to crush the rebellion. Then, according
- 3:39to the surviving accounts, the Welsh opened the battle. Welsh archers moved within effective
- 3:47range of the Norman army and began unleashing volleys of arrows against the stationary enemy.
- 4:02As previously noted, the Normans appear to have had little comparable missile capability with
- 4:09which to answer. Instead, their infantry had to endure the barrage. The front ranks
- 4:17tightened their formations and raised their almond shaped kite shields above their heads,
- 4:23attempting to protect themselves from the storm of arrows falling upon them.
- 4:41For the Norman soldiers, it may have seemed like something they simply had to endure. A
- 4:47brief storm, a temporary inconvenience. They expected their armor and shields to protect
- 4:55them until they could close with the Welsh and bring their superior close combat forces into
- 5:01action. But they were about to discover that the Welsh had no intention of allowing them to
- 5:07advance unchallenged. The arrows kept coming. Volley after volley crashed into the Norman
- 5:16formation. And what the Normans may have expected to be a passing storm was becoming something far
- 5:23more dangerous. The battle had only just begun. Norman casualties began to mount. Arrows were
- 5:33finding their way through slits, cracks, and any minor openings, resulting in sheer devastation.
- 5:40There is no detailed eyewitness account describing every movement on the battlefield,
- 5:45and the surviving sources leave much of the battle's sequence unclear. However, modern
- 5:51reconstructions suggest that the Norman cavalry eventually entered the fighting. It was clear that
- 5:58the Welsh archers had become too much of a threat. Robert Fitz Martin and Norman commanders appear
- 6:05to have committed their mounted forces, likely hoping to break the Welsh formation and bring
- 6:10the battle to a swift conclusion. Perhaps the Normans believed their cavalry could simply ride
- 6:17them down. The Norman cavalry began to advance. Among them were the elite of the Norman army,
- 6:25the mounted knights. Heavily armed and trained for mounted combat, Norman knights had earned a
- 6:31formidable reputation across Western Europe. Their combination of armor, horses, discipline, and
- 6:38shock tactics made them one of the most powerful military forces of the age. Their effectiveness
- 6:45had already been demonstrated repeatedly. At Hastings in 1066, Norman cavalry had played
- 6:52a crucial role in defeating the Anglo-Saxon army. During the first crusade, Norman and other Western
- 7:00European cavalry had again demonstrated their value in battles such as Doraleam in 1097. To
- 7:08the Norman commanders, the solution may have seemed straightforward. Close the distance.
- 7:14Break through the Welsh ranks. overrun the archers, then destroy the rest of the army.
- 7:43The Welsh front ranks closed together, presenting a formidable wall of shields
- 7:48and spears to the advancing cavalry. As the Norman horsemen crashed into the Welsh formation,
- 7:55the impact was tremendous. Men were knocked from their feet,
- 7:59formations were disrupted, and the Welsh front line was put under immense pressure.
- 8:18But it did not break. The Welsh warriors fought desperately to hold their ground. They knew what
- 8:25was at stake. Their lands, their homes, and the future of their resistance were all on
- 8:31the line. They had no intention of giving way. The Norman cavalry pressed the attack, relying on the
- 8:39tremendous shock of their mounted charges to break through the Welsh formation. But Norman cavalry
- 8:46were most dangerous when they had momentum. Against a dense formation of determined infantry,
- 8:52supported by long spears and protected by shields, the situation became far more difficult.
- 8:59The Marcel held their ground as the Norman horses pushed into the formation. Welsh infantry attacked
- 9:07from below, striking at the riders and their mounts whenever an opportunity presented itself.
- 9:13Some Norman horsemen were pulled from their saddles. The cavalry's initial momentum had faded
- 9:20and then gradually the momentum of the battle began to shift. The Welsh formation remained
- 9:26intact with the Welsh troops pressing forward together, forcing the Normans to give ground. What
- 9:34had begun as a Norman attempt to break the Welsh line was turning into a dangerous struggle for
- 9:40survival. By this point, the Norman cavalry saw no way through, and after sustaining casualties,
- 9:48they broke off the attack. Witnessing the collapse of their heavy knights and cavalry, the Norman
- 9:55infantry followed. The Welsh had taken what initially appeared to be an unfavorable situation
- 10:01and turned it into a stunning victory. The Norman retreat quickly descended into disaster. As the
- 10:08defeated army fled toward Cardigan and the river Ty, the Welsh pursued them relentlessly. Many were
- 10:15killed during the route, while others drowned attempting to cross the river.
- 10:21The exact casualties at Krug Mauo remain uncertain. Medieval sources give widely varying
- 10:27figures, many of which were likely exaggerated. What is clear is that Norman losses were severe
- 10:35and the Norman Flemish army had been decisively defeated. The consequences were significant.
- 10:42The victory strengthened the reputation of Owen Gwyneth and allowed Gwyneth to
- 10:47extend its influence farther into western Wales as Norman authority in the region weakened. However,
- 10:55the victory was not solely Gwyneth's. Griffith Appris and the forces of Deheubarth had played
- 11:01an important role in the campaign. Nevertheless, Krug Mau shifted the balance of power toward
- 11:08Gwyneth. The battle had demonstrated that the Normans could be defeated in the open field,
- 11:14checking their expansion across Wales. From the chaos of the rebellion, Gwyneth emerged as the
- 11:21strongest Welsh power, resisting Norman rule. The struggle for Wales would continue for generations,
- 11:28eventually ending with Edward I's conquest. But in 1136, the outcome was far from certain.
