They found remains of around 100 human bodies, of which eight had lesions to their bones. Most of the bodies, but not all, appeared to be young men.
The injuries included skull damage caused by massive blows or arrowheads, and some of the injuries appear to have been fatal.
One humerus (upper arm) bone contained an arrow head embedded more than 22mm into the bone, while a thigh bone fracture suggests a fall from a horse (horse bones were also found at the site).
The archaeologists also found remains of two wooden clubs, one the shape of a baseball bat and made of ash, the second the shape of a croquet mallet and made of sloe wood.
