Sumpter does it again!
I won't go into Mad Jack's biography, other than to say that John Percival was reputed to have commanded Victory's fore top at Trafalgar, not the ship. For Constitution buffs, Percival was a driving force within the Navy to save "Old Ironsides" and as a result, was given command of her on her subsequent circumnavigation (which included America's first military involvement in Viet Nam!)
I suggest that forum readers google "john percival" or "mad jack percival" for some fun reading.
A novelist would have a hard time inventing a character like Mad Jack and making him believable. Imagine a scene where missionaries have convinced the Hawaiian royalty to not allow "the trade" and the first US Navy vessel in the Hawaiian Islands arrives.
"Mad Jack Percival demanded an audience with Prime Minister Kalanimoku and the Dowager Queen (and regent) Kaahumanu. In his message, Percival asserted that denying women to his crew was an insult to the American flag." ( google "the battle of honolulu" to see what happened)
Both Herman Mellville and James Mitchner created characters in their novels based on Mad Jack.
Mad Jack Percival Day is celebrated at Pearl Harbor on the anniversary of Dolphin's departure from the Hawaiian Islands.
Percival is also commemorated in a folk song "The Balllad of Mad Jack" performed by "Schooner Fare" and a painting of Dolphin in Hawaii by marine artist Raymond Massey (http://www.shipstoregalleries.com/fineart/artists/massey/orig/dolphin_honolulu_o.html)
Sumpter, you're up again.
