JAUREYBO I. (how-ray'-e-bo), Caribbean cacique, born in Guadeloupe in the last half of the 15th century; died at sea in 1514. From the year 1511, when the natives of Porto Rico asked the Caribs of the neighboring islands to help them in their desperate struggle for freedom against the Spanish invaders, the Caribs made many incursions into that country. From 1511 to 1514 their most formidable leader was Jaureybo, who harassed the conquerors by his numerous invasions. His last exploit, which was carried out to revenge the death of his brother Cazimes, occurred about the middle of the year 1514. He landed, with 200 men, at the mouth of Loiza river, and attacked the neighboring farms, setting the buildings on fire and killing the inhabitants. One of the conquerors, Captain Sancho de Aragon, marched with a few men that had hastily been assembled against the invaders, but was totally defeated. Jaureybo withdrew his forces, prisoners, and plunder to the shore, and set out on his return to the Lesser Antilles. Don Cristobal de Mendoza, governor of Porto Rico, on hearing the news of Jaureybo's deed, pursued him with three ships manned by fifty men, and met the Caribbean craft at sunset near the island of Visques. Jaureybo, who might have escaped toward one of the islands near by, protected by the darkness, decided to resist. He led his canoes toward the ships, and did his best to board them, but, after a desperate struggle and the destruction of his craft, was killed.
