Emboldened by success, they formed organized companies of buccaneers and extended their depredations over the whole north Atlantic. Our southern commerce was particularly exposed. The accounts of piracy continually reaching our cities on the Atlantic coast, were accompanied with details of wanton cruelties inflicted on American seamen. The pirate craft were swift sailing schooners of from fifty to ninety tons burthen manned by crews of from twenty-five to one hundred men who knew every cove, crevice, nook and sinuous passage in the West India Archipelago. Watching like hawks for their prey, they would swoop down on the helpless quarry—British and American merchantmen—and rob, beat, burn and kill. The squadron fitted out to exterminate these heroes of our yellow-covered novels consisted of the frigates, _Macedonian_ and _Congress_, the sloops _Adams_ and _Peacock_, with five brigs, the steam galliot _Sea-gull_, and several schooners; among which was Lieutenant Perry’s twelve-gun vessel the _Shark_. The whole was under the command of Commodore David Porter, the father of the present illustrious Admiral of the American navy. The duty of ferreting out these pests was a laborious one in a trying climate. The commodore divided the whole West Indian coast into sections, each of which was thoroughly scoured by the cruisers and barges. The boat service was continuous, relieved by occasional hand-to-hand fights. Often the tasks were perplexing. Though belted and decorated with the universal knife, the quiet farmers in the fields, or salt makers on the coast, seemed innocent enough. As soon as inquiries were answered, and the visiting boat’s crew out of sight, they hied to a secluded cove. On the deck of a swift sailing light-draft barque or even open boat, these same men would stand transformed into blood-thirsty pirates, under black flags inscribed with the symbols of skull and bones, axe and hour glass. To the dangers of intricate navigation in unsurveyed and rarely visited channels, for even the Florida Keys were then unknown land, and their water ways unexplored labyrinths, and the fatigue of constant service at the oars, was added keen jealousy of the United States, felt by the Cubans, and shown by the Spanish authorities in many annoying ways. The acquisition of Cuba had even then been hinted at by Southern fire-eaters bent on keeping the area of African slavery intact, and even of extending it in order to balance the increasing area of freedom. This feeling, then confined to a section of a sectional party, and not yet shaped, as it afterwards was, into a settled policy and determination, roused the defiant jealousy of the Spaniards in authority, even though they might be personally anxious to see piracy exterminated. The Mexican war, waged in slavery’s behalf in the next generation, showed how well-grounded this jealousy was.
