1650, to oust the French and Hollanders from San Martin. The Spaniards
destroyed a fort that had been constructed there, but as soon as they
returned to this island the pirates reoccupied their nest. In 1657 an
Englishman named Cook came with a sufficient force and San Martin
became an English possession.

About 1665 the French Governor of Tortuga, Beltrán Ogeron, planned the
conquest of Puerto Rico. He appeared off the coast with 3 ships, but
one of the hurricanes so frequent in these latitudes came to the
island's rescue. The ships were stranded, and the surviving Frenchmen
made prisoners. Among them was Ogeron himself, but his men shielded
him by saying that he was drowned. On the march to the capital he and
his ship's surgeon managed to escape, and, after killing the owner of
a fishing-smack, returned to Tortuga, where he immediately commenced
preparations for another invasion of Puerto Rico. When he came back he
was so well received by the armed peasantry (jíbaros) that he was
forced to reembark.

From this time to 1679 several expeditions were fitted out in San Juan
to drive the filibusters from one or another of the islands in the
neighborhood. In 1780 a fleet was equipped with the object of
definitely destroying all the pirates' nests. The greater part of the
garrison, all the Puerto Ricans most distinguished for bravery,
intelligence, and experience, took part in the expedition. The fleet
was accompanied by the Spanish battle-ship Carlos V, which carried 50
cannon and 500 men. Of this expedition not a soul returned. It was
totally destroyed by a hurricane, and the island was once more plunged
in mourning, ruin, and poverty, from which it did not emerge till
nearly a century later.
