The size of the returning Norwegian fleet, according to later tradition, was dramatically smaller than the fleet that had arrived because so many warriors never returned.
Harold had destroyed one threat to his crown.
In another political universe, Stamford Bridge might have secured his reign.
He had responded with extraordinary speed.
He had defeated one of Europe's most experienced warrior kings.
His rebellious brother was dead.
The north had been saved.
Then news arrived from the south.
William had crossed the Channel.
The timing could hardly have been worse.
William Had Finally Received the Wind He Needed
While Harold marched north and fought Hardrada, William's invasion force waited.
The Norman fleet had moved along the French coast, eventually gathering around Saint-Valery-sur-Somme.
Favorable winds were essential.
When conditions changed, William crossed.
On September 28, 1066, only three days after Stamford Bridge, the Norman army landed at Pevensey on England's southern coast.
Harold had spent months waiting for exactly this invasion.
William arrived when the king and much of the English field army were hundreds of miles away recovering from another major battle.
If William had been able to choose the timing intentionally, he could scarcely have selected a better moment.
This is why Harold's reign feels almost cruelly compressed.
Every correct response created another vulnerability.
Had he ignored Hardrada, the north might have fallen.
By defeating Hardrada, he left the south temporarily open.
Harold now had to do something almost unbelievable again.
He had to march back.
William Built a Base Instead of Racing Inland
William did not immediately sprint toward London.
He established a secure position in Sussex.
Norman forces built fortifications, including castle structures at Pevensey and Hastings.
These early castles represented a military method the Normans would later expand across England.
A castle allowed a comparatively small force to control an area, protect supplies, and dominate surrounding routes.
William also needed Harold to come south.
The Norman army was strongest if concentrated.
Moving deep into England before establishing secure logistics could create danger.
So William devastated parts of the surrounding region.
This was not random.
Sussex lay within Harold's own power base.
By ravaging territory associated with the king, William placed political and personal pressure on him.
A ruler cannot easily ignore an invading army burning his land.
William could wait.
Harold felt compelled to move.
Harold Returned South at Extraordinary Speed
The English army had just fought Stamford Bridge.
Many men had marched hundreds of miles north.
Now they turned south.
Some troops remained behind.
Others joined Harold during the march.
How exhausted were the men who reached London and then Sussex?
Almost certainly very tired, though historians debate how much this should dominate explanations of Hastings.
Medieval warriors could march hard.
Harold may have gathered fresher troops along the route.
Still, the sequence was severe.
March north.
Fight a major battle.
March south.
Prepare to fight another major battle less than three weeks later.
Harold reached London.
He had options.
Some later accounts imply that advisers urged him to wait for more men.
Perhaps reinforcements from across the kingdom could have gathered.
Perhaps William could have been isolated.
Perhaps scorched-earth tactics could have weakened Norman supplies.
The evidence is uncertain.
What is clear is that Harold chose to confront William relatively quickly.
Why?
Confidence after Stamford Bridge may have played a role.
Political pressure mattered.
Allowing William to devastate Wessex indefinitely could damage Harold's authority.
He may also have hoped to surprise the Normans as he had surprised Hardrada.
This time, surprise failed.
The Two Armies Approached Hastings
The battle occurred on October 14, 1066.
The site was several miles from Hastings itself, near what would later become the town of Battle.
Harold positioned his army on high ground.
This was intelligent.
The English style of fighting favored a strong defensive formation.
The front rank locked shields.
Housecarls and fyrdmen stood together in a dense line.
Axes, spears, swords, and shields created a wall difficult for cavalry to penetrate.
The English did not have the same cavalry arm as the Normans.
William's army combined infantry, archers, and mounted knights.
This tactical diversity offered options.
The English possessed terrain and cohesion.
The Normans possessed combined arms and greater maneuverability.
The battle would become a test of whether Harold's shield wall could remain intact.
For hours, it did.
The English Shield Wall Was Formidable
Modern audiences sometimes imagine medieval battles as chaotic groups of men fighting individually.
Organized formations mattered enormously.
A shield wall works through cooperation.
Each man's protection overlaps with the next.
A single warrior stepping forward recklessly creates a gap.
A gap invites penetration.
Discipline therefore matters as much as strength.
Harold placed his standard and command position near the ridge.
His housecarls formed the professional core.
Some wore mail.
Many used the devastating long-handled Danish axe.
In close combat, such weapons could kill men and horses with terrifying force.
Norman knights charging uphill faced a disciplined line.
The English position had another advantage.
William had to attack.
Harold could remain.
The Norman duke had crossed the Channel to take a kingdom.
He could not simply wait forever beneath the ridge.
The Normans Attacked in Divisions
William's army appears to have been organized into regional groupings.
Normans formed the center.
Bretons fought on one wing.
Franco-Flemish or other allied contingents occupied another.
Archers opened parts of the battle.
Infantry advanced.
Cavalry followed.
The details vary among sources, but the general pattern involved repeated Norman attacks against the English position.
The shield wall held.
Norman losses mounted.
At one stage, the Breton wing broke or retreated.
A rumor spread that William had been killed.
This could have destroyed the invasion.
An army fighting for a claimant who suddenly dies can collapse rapidly.
William reportedly responded by showing his face and rallying the troops.
Later chroniclers present him lifting or removing his helmet and shouting that he was alive.
The exact words are unknowable.
The effect was real.
The Norman army did not disintegrate.
William restored control.
The battle continued.
Some Englishmen Broke Formation to Pursue
When part of the Norman army retreated, English warriors followed downhill.
This was dangerous.
The shield wall's strength existed in unity.
Men chasing a retreating enemy lost that protection.
Norman cavalry could turn and attack isolated pursuers.
Later accounts describe William exploiting this behavior deliberately through feigned retreats.
Historians debate how systematic the tactic was and whether every apparent retreat was planned.
At least some Norman forces clearly learned that English pursuit could break portions of the line.
Repeated attacks gradually reduced Harold's manpower.
The shield wall still resisted.
But a formation can remain visually intact while becoming thinner and more tired.
The battle lasted much of the day.
This mattered.
William did not need one dramatic charge if repeated pressure could eventually erode the defense.
Harold needed his men to remain disciplined until night.
Every hour brought darkness closer.
If the English survived until nightfall with their line intact, William's situation could become much more difficult.
The Norman duke was therefore fighting the clock as much as Harold had been fighting clocks all year.
Archery Became Part of the Late Battle
The Bayeux Tapestry and later accounts associate arrows with the final stage.
Norman archers may have adjusted their trajectories to send missiles higher into the English position.
Exactly how decisive this was is uncertain.
The famous story claims that Harold was struck in the eye by an arrow.
For generations, schoolbooks repeated the image almost as unquestioned fact.
