According to the ships surgeon, Nelson sustained a
"Compound fracture of the right arm by a musket ball passing through a little above the elbow; an artery divided; the arm was immediately amputated."
Eight years later Nelson received a injury that would prove fatal. At the Battle of Trafalgar, a bullet entered his left shoulder, passed through his spine and lodged two inches below his right shoulder blade.
When Nelson was close to death, he famously asked Vice Admiral Hardy to kiss him. Hardy kissed him on the cheek and Nelson asked who it was
"It is Hardy" he said.
"God bless you Hardy" was Nelson's last response.
