Modern medicine probably could not save Nelson at Trafalgar

Could modern medical care have saved Nelson from the wound he received at Trafalgar?

Probably not. The combination of arterial haemorrhage, spinal destruction, and extensive musket-ball trauma was effectively unsurvivable.

The medical answer is clear: modern treatment could reduce Nelson's pain but probably could not reverse his injuries. The musket ball caused major bleeding and destructive spinal trauma, leaving little realistic prospect of survival and a high likelihood of paralysis even under exceptional trauma care. Naval surgeons of Nelson's era still achieved surprisingly good survival among fit young sailors whose wounds were otherwise survivable.
