The wounds inflicted in battle, and post-battle ‘humiliation injuries’ inflicted on King Richard III highlight the manner of his death, the last English king to die in battle:

“Ten peri-mortem wounds have been identified on the remains, eight on the skull and
two on the post-cranial skeleton. Two large wounds underneath the back of the skull,
consistent with a halberd and a sword blow, are likely to have been fatal. A third, smaller,
penetrating wound to the top of the skull is more enigmatic, but may have been caused by a sharp blow from a pointed weapon, such as a dagger, on the crown of the head.

“Other wounds were more superficial and none of the skull injuries could have been inflicted on someone wearing a helmet of the type favoured in the late fifteenth century. Two wounds, a cut on a right rib and a cut to the right pelvis typical of a thrust through the right buttock, are again unlikely to have been inflicted on someone wearing armour. These, along with two wounds to the face, may be ‘humiliation injuries’ delivered after death.”
