These semi-pirates, whom the French governor dared not openly support yet feared to disavow, were a constant source of trouble to the Governor of Jamaica. They did not scruple to attack English traders and fishing sloops, and when pursued took refuge in Petit Goave, the port in the _cul-de-sac_ at the west end of Hispaniola which had long been a sanctuary of the freebooters, and which paid little respect to the authority of the royal governor.[455] In Jamaica they believed that the corsairs acted under regular commissions from the French authorities, and Sir Thomas Lynch sent repeated complaints to de Pouancay and to his successor. He also wrote to England begging the Council to ascertain from the French ambassador whether these governors had authority to issue commissions of war, so that his frigates might be able to distinguish between the pirate and the lawful privateer.[456] Except at Petit Goave, however, the French were really desirous of preserving peace with Jamaica, and did what they could to satisfy the demands of the English without unduly irritating the buccaneers. They were in the same position as Lynch in 1671, who, while anxious to do justice to the Spaniards, dared not immediately alienate the freebooters who plundered them, and who might, if driven away, turn their arms against Jamaica. Vanhorn himself, it seems, when he left Hispaniola to join Laurens in the Gulf of Honduras, had been sent out by de Pouancay really to pursue "La Trompeuse" and other pirates, and his lieutenant, de Grammont, delivered letters to Governor Lynch to that effect; but once out of sight he steered directly for Central America, where he anticipated a more profitable game than pirate-hunting.[457]
