Backstory
Treasure Island contains numerous references to fictional past events, gradually revealed throughout, that shed light upon the events of the main plot.
These refer to the pirate Captain J. Flint, "the bloodthirstiest buccaneer that ever lived", who is dead before "Treasure Island" begins. Flint was captain of the Walrus, with a long career chiefly in the West Indies and along the coasts of the southern American colonies. His crew included a number of characters who also appear in the main story: Flint's first mate, William (Billy) Bones; his quartermaster John Silver; his gunner Israel Hands; and among his other sailors: George Merry, Tom Morgan, Pew, "Black Dog" and Allardyce (who becomes Flint's "pointer" toward the treasure). Many other former members of Flint's crew were on the Hispaniola, though it is not always possible to identify which were Flint's men and which later agreed to join the mutiny — such as the boatswain Job Anderson and a mutineer "John", killed at the rifled treasure cache. Flint and his crew were successful, ruthless, feared ("the roughest crew afloat") and rich, provided they could keep their hands on the money they stole. The bulk of the treasure Flint made by his piracy — £700,000 worth of gold, silver bars and a cache of armaments — was buried on a remote Caribbean island. Flint brought the treasure ashore from the Walrus with six of his sailors, and built a stockade on the island for defence. When they had buried the treasure, Flint returned to the Walrus alone -—having murdered the other six. A map to the location of the treasure he kept to himself until his dying moments.
The whereabouts of Flint's money and his crew are obscure immediately thereafter, but they ended up in the town of Savannah, Province of Georgia. Flint was ill, and his sickness was not helped by his immoderate consumption of rum. On his sickbed, he sang the sea shanty "Fifteen Men" and ceaselessly called for more rum, with his face turning blue. His last living words were "Darby M'Graw! Darby M'Graw!", and then, following some profanity, "Fetch aft the rum, Darby!" Just before he died, he passed on the treasure map to the mate of the Walrus, Billy Bones (or so Bones always maintained). After Flint's death, the crew split up, most of them returning to England. They disposed of their shares of the unburied treasure diversely. John Silver held on to £2,000, putting it away safe in banks, and became a waterfront tavern keeper in Bristol, England. Pew spent £1,200 in a single year and for the next two years afterwards begged and starved. Ben Gunn returned to the treasure island with crew mates to try to find the treasure without the map, and as his efforts failed, he was marooned on the island and left. Bones, knowing himself to be a marked man for his possession of the map, looked for refuge in a remote part of England. His travels took him to the rural West Country seaside village of Black Hill Cove and the inn of the 'Admiral Benbow'.
