Even if he knew it by heart, a man in my disturbed, befuddled condition couldn’t have quoted a syllable of his own country’s history.

“Well?” Captain Nemo went on. “Did you hear my question? Do you know the history of Spain?”

“Very little of it,” I replied.

“The most learned men,” the captain said, “still have much to learn. Have a seat,” he added, “and I’ll tell you about an unusual episode in this body of history.”

The captain stretched out on a couch, and I mechanically took a seat near him, but half in the shadows.

“Professor,” he said, “listen carefully. This piece of history concerns you in one definite respect, because it will answer a question you’ve no doubt been unable to resolve.”

“I’m listening, captain,” I said, not knowing what my partner in this dialogue was driving at, and wondering if this incident related to our escape plans.

“Professor,” Captain Nemo went on, “if you’re amenable, we’ll go back in time to 1702. You’re aware of the fact that in those days your King Louis XIV thought an imperial gesture would suffice to humble the Pyrenees in the dust, so he inflicted his grandson, the Duke of Anjou, on the Spaniards. Reigning more or less poorly under the name King Philip V, this aristocrat had to deal with mighty opponents abroad.

“In essence, the year before, the royal houses of Holland, Austria, and England had signed a treaty of alliance at The Hague, aiming to wrest the Spanish crown from King Philip V and to place it on the head of an archduke whom they prematurely dubbed King Charles III.

“Spain had to withstand these allies. But the country had practically no army or navy. Yet it wasn’t short of money, provided that its galleons, laden with gold and silver from America, could enter its ports. Now then, late in 1702 Spain was expecting a rich convoy, which France ventured to escort with a fleet of twenty-three vessels under the command of Admiral de Chateau-Renault, because by that time the allied navies were roving the Atlantic.
