There were at this time four small States on the southern shores of the Mediterranean Sea called the Barbary Powers, which had for many years derived much profit from the detestable practice of sending out piratical ships to plunder the merchant-vessels of all nations. The European States from time to time made an attempt to put the pirates down, and sometimes a great nation had even paid them money on condition that they should not molest its commerce. There is some ground for thinking that England, of whom the Barbary Powers were most afraid, rather encouraged their depredations than sought to check them, because it was for her advantage, as a trading State, that foreign merchant-fleets should suffer, in order that the field might be left clear to her. However this may be, the English had never put forth their naval strength against the corsairs; yet English merchantmen were mostly spared by them. Before the Revolution the vessels of the Colonies, bearing as they did the English flag, had all the privileges of other English ships; but when the war was over, and the merchantmen of the young American State began to reappear in the Mediterranean with a new and hitherto unknown American flag, the Barbary cruisers pounced upon them as their lawful prey. The first piratical capture was made in 1785, and was a Boston ship, the schooner "Maria." Soon afterward the "Dolphin," of Philadelphia, was seized. These were carried into Algiers, where the ships and their cargoes were confiscated by the Dey, and the crews were held in slavery. It seems strange that there should not have been enough of public spirit in the country to fit out ships at once and send them over to set free the Americans who were enslaved by these Turkish outlaws, or at least to protect from their barbarities other Americans navigating the seas. But no such measures were taken, and the prisoners were left to languish in captivity until their buccaneering captors received a heavy ransom. Agents were indeed sent out, who did much chaffering with the Algerines, mostly through foreign officials; but for a long time this brought about no result, and several of the captives meanwhile died.
