1066 (August)
William’s fleet 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.
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.
1066 (30th September)
William decided to move the Norman army to Hastings as it 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. 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. 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)

1067 (after 7th December) or 1068 (during)
