a "sink or nest of infamous rascals". Until Rogers obtained his commission, the islands had been nominally governed by absentee Lords Proprietor, who did little except appoint a new, powerless governor when the position fell vacant. Under the agreement that underlay Rogers' commission, the Lords Proprietor leased their rights for a token sum to Rogers' company for twenty-one years. On 5 September 1717, a proclamation was issued announcing clemency for all piratical offences, provided that those seeking what became known as the "King's Pardon" surrendered not later than 5 September 1718. Colonial governors and deputy governors were authorised to grant the pardon. Rogers was officially appointed "Captain General and Governor in Chief" by George I on 6 January 1718. He did not leave immediately for his new bailiwick, but spent several months preparing the expedition, which included seven ships, 100 soldiers, 130 colonists, and supplies ranging from food for the expedition members and ships' crews to religious pamphlets to give to the pirates, whom Rogers believed would respond to spiritual teachings. On 22 April 1718, the expedition, accompanied by three Royal Navy vessels, sailed out of the Thames. First term The expedition arrived on 24 July 1718, surprising and trapping a ship commanded by pirate Charles Vane. After negotiations failed, Vane used a captured French vessel as a fireship in an attempt to ram the naval vessels. The attempt failed, but the naval vessels were forced out of the west end of Nassau harbour, giving Vane's crew an opportunity to raid the town and secure the best local pilot. Vane and his men then escaped in a small sloop via the harbour's narrow east entrance. The pirates had evaded the trap, but Nassau and New Providence Island were in Rogers' hands. At the time, the island's population consisted of about two hundred former pirates and several hundred fugitives who had escaped from nearby Spanish colonies. Rogers organised a government, granted the King's Pardon to those former pirates on the island who had not yet accepted it, and started to rebuild the island's fortifications, which had fallen into decrepitude under pirate domination. Less than a month into his residence on New Providence, Rogers was faced with a double threat: Vane wrote, threatening to join with Edward Teach (better known as Blackbeard) to retake the island, and Rogers learned that the Spanish also planned to drive the British out of the Bahamas.
