Bab el Mandeb

Bab el Mandeb, whose Arabic name translates to "Gate of Tears," is the strategic strait that forms the southern gateway to the Red Sea, connecting it to the Gulf of Aden and the broader Indian Ocean. For the Nautilus, this narrow waterway represents a decisive transition point in its underwater tour, marking the entry into a sea rich with biblical history and unique marine life, a sea that Captain Nemo navigates with the same blend of scientific curiosity and deliberate isolation that defines his entire voyage.

Geography and Strategic Importance

The strait is approximately twenty miles wide and fifty-two kilometers long, a relatively short passage that the Nautilus, launched at full speed, clears in barely an hour. Its waters are a major thoroughfare for global commerce, plied by numerous English and French steamers on routes from Suez to Bombay, Calcutta, Melbourne, Réunion Island, and Mauritius. This heavy traffic forces the Nautilus to remain submerged, avoiding the surface where it might be sighted. The strait's strategic value is underscored by the British fortifications on Perim Island, which strengthen the position of Aden, a key colonial port captured by the British in 1839.

The Nautilus's Passage

The Nautilus enters the Strait of Bab el Mandeb on February 7, 1868, after having cruised in sight of the city of Aden the previous day. Professor Aronnax, who had been convinced that Captain Nemo would turn back from this seemingly landlocked sea, is surprised when the captain instead commits to the passage. The Nautilus wisely stays in midwater, avoiding the many ships that crowd the narrows. The crossing is swift and uneventful, and by noon, the ship is plowing the waves of the Red Sea itself, leaving the Indian Ocean behind.

Narrative and Thematic Significance

The passage through Bab el Mandeb is a pivotal moment in the voyage, as it definitively commits the Nautilus to the Red Sea, a body of water that Captain Nemo describes as having an "abominable reputation" among ancient historians. The captain's decision to enter this sea, despite its dangers and its proximity to populated shores, reveals his willingness to navigate even the most historically treacherous waters. The strait's name, "Gate of Tears," resonates with the novel's themes of loss and separation, foreshadowing the sorrowful events that will later unfold in the Red Sea, including the death of a crewman and the subsequent coral burial. The passage also demonstrates the Nautilus's ability to move freely between the world's oceans, a mobility that is both its greatest strength and the source of its passengers' captivity.
