Harold Godwinson, Earl of Wessex, was shipwrecked off the coast of Ponthieu. On hearing of the shipwreck, William, Duke of Normandy ordered that Harold be brought to him. Some sources claim that Harold was kept under house arrest but it may have been that his ship was badly damaged and needed extensive repairs or he may have remained in Normandy to secure the release of his brother and nephew who had been taken as hostages. It is known that Harold willingly rode into battle with William and helped to defeat Conan II of Brittany. William knighted Harold for his part in the battle. Afterwards, Harold returned to England with his nephew Haakon. The Normans later claimed that before leaving Harold  swore an oath to support William’s claim to the throne of England after the death of Edward. The oath is not recorded in any Anglo-Saxon sources.

King Edward the Confessor died

1066 (late January)
Council of Lillebonne
This was a meeting of Duke William’s most trusted advisers. William FitzOsbern was one of those that spoke in support of invading England. The council decided to support William’s proposed invasion of England and began making plans.
1066 (20th May)
William of Normandy made a case against Harold and presented it to the Pope. He was successful and gained papal backing for his invasion. The Pope sent him a banner to carry into battle.

1066 (18th June)
William’s daughter, Cecilia entered the abbey of the Holy Trinity in Caen as a novice
1066 (Summer)
Throughout the Summer William assembled a fleet of ships to carry his army across the Channel to England. William’s wife, Matilda of Flanders, paid for a ship to transport William, the Mora.
1066 (4th August)
William’s fleet of around 1,000 ships was ready to sail but he delayed sailing, possibly due to unfavourable wind direction and possibly because he was waiting for harvest season in the hopes that some of the men stationed along the South coast would go home. While waiting to sail William had to provide food and provisions for up to 14,000 men and 3,000 horses.
1066 (early September)
William, decided not to wait for favourable weather and put his fleet to sea. The ships were unable to withstand the powerful stormy weather and those that survived were forced to put in to port at St Valery-sur-Somme.
1066 (28th September)
William, Duke of Normandy sailed overnight and landed at Pevensey on the South coast of England in the morning. He was surprised to find no army waiting for him. It is said that he stumbled as he got out of his boat onto the shore and there was some concern that it could be a bad omen.
1066 (30th September)
The Duke decided to move the Norman army to Hastings as there was insufficient food in Pevensey to feed the army for more than a few days. Hastings also offered better defence and a more direct route to London.
1066 (early October)
William remained in Hastings confident that Harold would march South and challenge his presence. Staying put also had the advantage that William’s men would be rested before any battle whereas Harold’s men had marched north, fought a battle then marched south again.
1066 (13th October)
William’s scouts reported that the Saxon army had arrived and were camped on Caldbec Hill. William told his men to be ready in case of a night attack.
1066 (14th October)

Battle of Hastings
Early in the morning William marched north to meet the Saxons. Harold knew he did not have enough men to defend Caldbec Hill so moved to Senlac Hill where his army formed a shield wall.

William arrived and set up his forces at the bottom of the hill. He had three groups – Normans, Flemings and Bretons, both cavalry and infantry. William opened the battle with a barrage of arrows which, because of the hill flew over the heads of the Saxons. Next William sent in his infantrymen but they were unable to break through the shield wall. A group of Breton infantrymen turned and ran down the hill. The Saxons that had been withstanding that group broke the shield wall and ran down after them. William ordered that they become the focus of the next attack and although some managed to return to their line most were cut down. It is thought that Harold’s two brothers lost their lives at this point.

Having seen how the Bretons fleeing down the hill broke the shield wall, William changed tactic and ordered his men to do the same thing. Although the shield wall did not break so spectacularly again it did begin to weaken. With the light beginning to fade William ordered his archers to fire again but to angle them higher so that they hit the men just behind the shield wall. It is thought that one of these arrows went through the eye slit of Harold’s helmet and struck him in the eye or near to the eye. While he was reeling from the attack it is believed that he was cut down and killed.With Harold dead and most of the leading nobles also dead many of the remaining men fled the battlefield. Those that remained were soon cut down. William was victorious.

1066 (15th October)
William surveyed the battlefield and instructed that the dead be buried.
