As the narrative draws to a close, the focus shifts from the intensity of combat to the arduous task of securing the "vast treasure." The narrator describes the process of filling "canvas sacks" with gold, a repetitive yet rewarding endeavor. This period was marked by a sense of awe as the crew cataloged a global collection of wealth. The narrator marvels at the diversity of the loot, noting "Spanish doubloons," "Venetian ducats," and even "square coins with holes in the middle from far away China." Describing the tactile sensation of the wealth, the narrator remarks on "sifting through them," letting the coins fall "like autumn leaves through my fingers." This imagery underscores the sheer magnitude of the treasure that had driven their conflict.
Security remained a constant concern due to the "three remaining pirates" who haunted the island. The crew’s approach to these mutineers was pragmatic and severe. Silver, despite his attempts to maintain a civil demeanor, was treated with deep suspicion, "kept at a distance, like a dog leashed to a post." Recognizing that the mutineers could not be trusted and that bringing them home for trial was futile, the crew decided to "maroon the mutineers." They provided the outcasts with "a good stock of sail, as well as tools, food, and other supplies" before departing. The final interactions were tense; as the crew sailed away, the mutineers could be seen in the shallows, "begging us to take them along." The encounter ended in a final act of hostility when the mutineers "fired on us," narrowly missing Silver.
Leaving behind the "craggy peaks" of Treasure Island brought the narrator "a great joy." However, the journey home was not without its final complication. Upon reaching Spanish America, the crew discovered that Long John Silver had orchestrated one final maneuver. Ben Gunn, left alone on deck, reported that "Silver had taken a small craft and some sacks of treasure and had made off." Rather than causing distress, this revelation brought a sense of relief to the crew, as they knew he was "gone for good." This departure serves as the final chapter in Silver’s complex role as both mentor and villain, leaving him to likely reunite with his "parrot, Captain Flint."
The concluding reflections reveal the divergent paths taken by the survivors. The distribution of the wealth led to varied outcomes: Gray invested his share in education and maritime ownership, while Ben Gunn squandered his "one thousand pounds within three weeks." The captain opted for retirement, leaving the life of adventure behind. For the narrator, the experience left a permanent psychological scar. Despite the allure of the remaining gold, the narrator asserts, "I shall never return." The haunting memories of the "booming surf" and the shrill, repeated cries of "Pieces of eight, pieces of eight" from Captain Flint serve as a somber reminder that some treasures are not worth the price of the trauma they inflict.
