On 14 October 1066, on a ridge near Hastings, a Norman duke gambled everything he had on a single day of battle, and by nightfall he had won a kingdom.
William the Conqueror, Duke of Normandy, had crossed the Channel to claim the English throne. Against him stood King Harold Godwinson and the Anglo-Saxon shield wall, and for most of the day the two armies were locked in a brutal, even struggle.

In one day at Hastings, he won a kingdom and remade a nation.
By combining archers, infantry and heavy cavalry, and luring the English out of position with feigned retreats1, William finally broke the shield wall and killed Harold. The Norman Conquest that followed would reshape England's language, laws and ruling class for centuries.
How William won a kingdom
William's success rested on nerve, combined arms and a ruthless grip on what he had taken.
- Stake everything on one battle. He gambled an entire invasion on a single day at Hastings, knowing defeat would leave him stranded and doomed.
- Combined arms. He coordinated archers, infantry and heavy cavalry, a flexibility that Harold's static shield wall could not answer.
- The feigned retreat. His cavalry pretended to flee, drew parts of the English line down the hill after them, then turned and cut them down.
- Hold what you take. He secured England with a network of castles, from the Tower of London outward, that pinned down a hostile country.
- Survey and control. The Domesday Book of 1086 recorded who held what across England, so he could tax and rule his conquest to the last hide of land.

1066 and the Battle of Hastings
The death of England's king in 1066 left a disputed throne, and William was one of the claimants. He landed on the south coast and met Harold1's army near Hastings. The Anglo-Saxon shield wall held for hours, until William's feigned retreats and relentless cavalry finally broke it and Harold was killed, reportedly by an arrow.

Remaking England
Winning the battle was only the start. William crushed rebellions, most brutally in the harrying of the north3, and covered the country in castles. He replaced the English aristocracy with Norman lords2, and his Domesday survey mapped the kingdom in astonishing detail. Norman French reshaped the English language, and the country he seized in a day was changed for good.
