The last of the great privateering voyages for which Drake had set the example was the armament which Lord George Clifford, Earl of Cumberland, sent against Porto Rico in 1598. The ill-starred expeditions of Raleigh to Guiana in 1595 and again in 1617 belong rather to the history of exploration and colonization. Clifford, "courtier, gambler and buccaneer," having run through a great part of his very considerable fortune, had seized the opportunity offered him by the plunder of the Spanish colonies to re-coup himself; and during a period of twelve years, from 1586 to 1598, almost every year fitted out, and often himself commanded, an expedition against the Spaniards. In his last and most ambitious effort, in 1598, he equipped twenty vessels entirely at his own cost, sailed from Plymouth in March, and on 6th June laid siege to the city of San Juan, which he proposed to clear of Spaniards and establish as an English stronghold. Although the place was captured, the expedition proved a fiasco. A violent sickness broke out among the troops, and as Clifford had already sailed away with some of the ships to Flores to lie in wait for the treasure fleet, Sir Thomas Berkeley, who was left in command in Porto Rico, abandoned the island and returned to rejoin the Earl.[50] The English in the sixteenth century, however, had no monopoly of this piratical game. The French did something in their own way, and the Dutch were not far behind. Indeed, the French may claim to have set the example for the Elizabethan freebooters, for in the first half of the sixteenth century privateers flocked to the Spanish Indies from Dieppe, Brest and the towns of the Basque coast. The gleam of the golden lingots of Peru, and the pale lights of the emeralds from the mountains of New Granada, exercised a hypnotic influence not only on ordinary seamen but on merchants and on seigneurs with depleted fortunes. Names like Jean Terrier, Jacques Sore and Francois le Clerc, the latter popularly called "Pie de Palo," or "wooden-leg," by the Spaniards, were as detestable in Spanish ears as those of the great English captains. Even before 1500 French corsairs hovered about Cape St Vincent and among the Azores and the Canaries; and their prowess and audacity were so feared that Columbus, on returning from his third voyage in 1498, declared that he had sailed for the island of Madeira by a new route to avoid meeting a French fleet which was awaiting him near St Vincent.[51] With the establishment of the system of armed convoys, however, and the presence of Spanish fleets on the coast of Europe, the corsairs suffered some painful reverses which impelled them to transfer their operations to American waters. Thereafter Spanish records are full of references to attacks by Frenchmen on Havana, St. Jago de Cuba, San Domingo and towns on the mainland of South and Central America; full of appeals, too, from the colonies to the neglectful authorities in Spain, urging them to send
