Part 2, Chapter 21 of 46 · 12 min to read the chapter

In Chapter 21, Captain Nemo confronts an unidentified warship, prevents his prisoners from escaping, and sinks the vessel by striking beneath its armor. His claim that the enemy destroys his family gives his revenge a personal cause, while the narrator witnesses the crew’s deaths and Nemo’s tears before a family portrait.

What happens

  1. A warship approaches and fires on the Nautilus, while Ned Land hopes to reach it and escape.
  2. Nemo knocks Ned down for signaling, raises a black flag, and declares his intention to sink the ship.

  4. The narrator, Ned, and Conseil plan to escape, but the closed hatch and the submarine’s dive trap them.
