BBC News has the details:
Sarah Hainsworth, study author and professor of materials engineering, said: “Richard’s injuries represent a sustained attack or an attack by several assailants with weapons from the later medieval period.
“Wounds to the skull suggest he was not wearing a helmet, and the absence of defensive wounds on his arms and hands indicate he was still armoured at the time of his death.”
Guy Rutty, from the East Midlands pathology unit, said the two fatal injuries to the skull were likely to have been caused by a sword, a staff weapon such as halberd or bill, or the tip of an edged weapon.
He said: “Richard’s head injuries are consistent with some near-contemporary accounts of the battle, which suggest Richard abandoned his horse after it became stuck in a mire and was killed while fighting his enemies.”
