Not infrequently it was difficult to separate privateering from piracy. John Quelch, who was hanged in Boston for piracy, in 1704, preyed upon Portuguese commerce as he supposed in safety and not until he returned to Marblehead did he learn of the treaty of peace that made him a pirate. In 1653, Thomas Harding captured a rich prize sailing from Barbadoes and in consequence was tried in Boston for piracy, but saved his neck when he was able to prove that the vessel was Dutch and not Spanish. In 1692, the Governor and Council of Connecticut were informed that “a catch and 2 small sloops, with about 30 or 40 privateers or rather pirates,” were anchored off East Hampton, Long Island, and had sold a ketch to Mr. Hutchinson of Boston and bought a sloop of Captain Hubbard, also of Boston. Newport, R. I., sent out many privateers. In 1702 it was reported that nearly all of the able-bodied men on the Island were away privateering. The town also profited frequently from the visits of known pirates, as in 1688, when Peterson, in a “barkalonga” of ten guns and seventy men, refitted at Newport and no bill could be obtained against him from the grand jury as they were neighbors and friends of many of the men on board. Two Salem ketches also traded with him and a master of one brought into “Martin’s Vineyard,” a prize that Peterson “the pirate, had taken in the West Indies.”[12] Andrew Belcher, a well-known Boston merchant and master of the ship “Swan,” paid Peterson £57, in money and provisions, for hides and elephants’ teeth taken from his plunder. The ill-defined connection between privateering and piracy was fully recognized in those days and characterized publicly by the clergy. In 1704 when Rev. Cotton Mather preached his “Brief Discourse occasioned by a Tragical Spectacle in a Number of Miserables under Sentence of Death for Piracy,” he remarked that “the Privateering Stroke so easily degenerates into the Piratical; and the Privateering Trade is usually carried on with an Unchristian Temper, and proves an Inlet unto so much Debauchery and Iniquity.” The Treaty of Aix-la-Chapelle, by which peace was made between England and Spain, was signed in 1668, but the colonial authorities were so little concerned by the depredations of the English privateers on Spanish commerce in the West Indies that their commissions were not revoked until 1672 and even then, for a time, the doings of the adventurous, privately armed vessels were not scrutinized too closely.
