King Richard III suffered before he died...his feet went missing, he took a severe beating at Bosworth battlefield, and suffered from terrible backache all his adult life. The missing feet, however, are a completely different story.
But that's not all. The king suffered greatly before dying, and his dignity suffered afterwards. Richard III's wounds were on all sides, but mostly on the back, suggesting he was surrounded at death and fought hard: as one contemporary report put it, “to his last breath he held himself nobly in a defending manner.”
Some of the wounds he received after death; they could not have been received through armor. Contemporary reports said the 32-year-old king was stripped of armor and clothes. Regardless of what kind of king Richard III was, he was brave enough to face his end in battle — the last English king to do so.
