In my history blog, I came across a picture of the Great White Fleet in Venezuela. It was either that fleet that made its first stop in that country, or a naval squadron sent to show the flag.
Found out it was commanded by Rear Admiral Robley "Fighting Bob" Evans commanded it.
As a lieutenant, Evans had participated in the Naval Column attack on Fort Fisher and had been wounded four times on Jan. 15, 1865. Back on board ship, it was determined by the surgeon that his foot would have to come off, at which point he threatened to shoot anyone he caught trying to amputate his foot.
Outcome: the foot stayed on and no one got shot.
