How privateers became pirates is well shown by a case that occurred in the latter half of the seventeenth century. A vessel went cruising from the Carolinas, and after being out for eighteen months had gained so few prizes that the crew began to complain. After discussing the situation, they resolved to try the South Sea, where they hoped to find the Spaniards less prepared. Meeting with very bad weather at the entrance of the Strait of Magellan, they were, however, obliged to turn back, and then the majority decided to become pirates. Eight men who refused to agree were marooned on the island of Fernando Po, their late comrades leaving them a small boat in which they expected to be able to get to some English colony.
The vessel left, and commenced her piratical work at once by capturing a Portuguese ship larger than herself, the crew being brought and landed on the same island. In the night the Portuguese made off, taking with them the Englishmen's boat as well as their own, leaving the eight privateers to do the best they could. However, they were not easily daunted, and at once began to cut down trees and build a sloop of four tons, which they finished in six weeks, meanwhile living on sea fowl and their eggs, which were plentiful. Finally they sailed for Tobago, but missing that island got to Tortuga, where they arrived almost perishing with hunger and thirst, having had nothing to eat or drink for six days. Even then they were not discouraged, but after resting awhile, set sail in the same boat for New England, passing along the Spanish islands, often unable to land for water on account of the enemy, and lying under cover of the mangroves, to be almost devoured by mosquitoes. Even with all this care they were taken at last, stripped, thrust down in the hold of a Spanish _guarda-costa_, and finally kept as slaves in the island of Cuba.
In the early years of the seventeenth century few of the adventurers had any commissions, but as the mother countries began to establish settlements, letters of marque were granted when there was a war. The corsairs and pirates then became privateers, only to go back to their old trade when peace was nominally restored. Some played fast and loose with these commissions, sometimes having both French and English at the same time, either to be used according to circumstances. The French Governors went so far as to sell these documents signed and sealed, but without names, so that they passed from hand to hand ready to be filled up when the pirate wished to escape the yard-arm. The young colonies were too weak to incur their displeasure--in fact they were glad to encourage their visits, as the settlers could always pick up good bargains when they sold their booty. Yet, with all that, there was a dread of them, even among their own countrymen, which prevented that feeling of safety which best consists with the progress of a colony.
