The Norman war cry "Ut! Ut! Ut! (Out! Out! Out!)" interrupted Elmer's thoughts. Again and again the Norman arrows fell against the English shield wall. Again and again the Norman horses charged up the hill, but the English drove them off with their great axes. Nothing could break the strong shield wall.
Now the Norman soldiers were getting nearer. The Anglo-Saxons waited until they were close. Then they brought out their secret weapon — the slingshot. The right side of the Norman army began to go back. Elmer's heart jumped with joy when they turned and ran! Many of the Anglo-Saxons ran after them. They wanted to chase the Normans back into the sea.
But at the bottom of the hill the rest of the huge, well-trained Norman army was waiting. It was a trap. They attacked the Anglo-Saxons who had run down the hill and killed them all.
After that things began to get worse for the Anglo-Saxons. They lost courage. The Norman archers began to shoot their arrows high into the air. The arrows fell at the back of the English army. One of the arrows killed King Harold. It hit him in the eye.
He died and with him Anglo-Saxon Britain died too. Britain now belonged to William of Normandy.
