Ah, the duelling surgeon anecdote! One of my favorites. Gangrene and infections probably DID kill more men than the pistol bullets, so at least he'd determined to avoid THAT risk...
My favorite, though, was the fellow who'd lost a leg in the army and who, when challenged, sent his surgeon with complete instrument kit to his opponent along with the generous offer to let him choose which of HIS legs the surgeon would amputate---since the rules of duelling required that they fight "on an equal footing"...
