What happens in Chapter 15 of Moby-Dick?
The second day of the Pequod's hunt for Moby Dick begins with the crew already on edge after the violence and loss from the first day. Ahab, having had his ivory leg shattered in that encounter, has a new one fashioned from the Pequod's spare spars and takes his position at the helm with a fierce, almost otherworldly intensity. The white whale surfaces again, and the three boats are lowered. This time, the lines become hopelessly tangled: Ahab's boat is caught in a chaotic whirl of rope and wreckage as Moby Dick turns and charges. Fedallah, Ahab's Parsee shadow, ends up ensnared by the fouled harpoon lines—pulled underwater and drowned, his body only a dark shape wrapped around the whale. Ahab survives but loses his new ivory leg completely. Starbuck urges again for the chase to be called off, referencing Fedallah's prophecy that Ahab would see him once more before his death. Ahab, realizing that the prophecy is already partly fulfilled, refuses to turn back—he interprets it as a sign that he cannot die today. The crew, weary and rattled, is told to rest. Ahab keeps the night watch by himself, gazing into the dark water.
Analysis
Melville structures the second day as a tightening of the tragic mechanism he initiated on the first. While Day One established the whale's power, Day Two dismantles Ahab's proxies: his false leg is destroyed once more, and Fedallah—his occult double, reflecting his dark will—is consumed by the very creature Ahab hunts. The tangled harpoon lines serve as the chapter's central image: rope as fate, complicity, and the literal binding of one man's doom to another's. Melville captures the chaos of the chase through long, syntactically complex sentences that mirror the physical entanglement on the page.
Starbuck's intervention serves as the chapter's moral fulcrum, and Melville gives it weight by having Ahab listen and then twist the prophecy's logic into a justification for moving forward. This is Ahab at his most intellectually dangerous: not ignoring reason but colonizing it. The Parsee's corpse tied to the whale's flank becomes a grotesque figurehead, a memento mori that Moby Dick now carries into the third day. Here, Melville's tonal register shifts from epic grandeur to something colder—the sublime dissipates, leaving only dread. Ahab's solitary night watch, the chapter's quiet closing image, removes the crew entirely and presents a man who has outlasted his own mythology and is yet unaware of it.
Key quotes from Chapter 15
“Aye, aye! and I'll chase him round Good Hope, and round the Horn, and round the Norway Maelstrom, and round perdition's flames before I give him up.”
Ahab's declaration, repeated with variation across the novel, here takes on retrospective irony as Fedallah's death confirms the prophecy is in motion.
“The harpoon was darted; the stricken whale flew forward; with igniting velocity the line ran through the groove;—ran foul. Ahab stooped to clear it; he did clear it; but the flying turn caught him round the neck, and voicelessly as Turkish mutes bowstring their victim, he was shot out of the boat.”
Melville's account of Ahab being hurled from the boat by the line captures the mechanical indifference of fate—the whale need not even intend his destruction.
“I see my object; I will have it; and what is more, I will have it before long.”
Ahab's terse assertion to Starbuck after losing his second ivory leg, its brevity a measure of how far beyond argument he has moved.
