In 1576 Antwerp was sacked and burned; in 1585 the town was reduced to starvation by the Duke of Parma, and its commerce having been scattered by successive disasters, some of it migrated to Amsterdam, and some sought shelter in the Thames. In London the modern man was protected by the sea, and the crisis of the combat came in 1588, when the Spaniards, having decided to pursue their enemy to his last stronghold, sent the Armada to perish in the Channel. With that supreme effort the vitality of the great imaginative empire began to fail, disintegration set in, and on the ruins of Spain rose the purely economic centralization of Great Britain. Like the Venetians, the British laid the basis of their high fortune by piracy and slaving, and their advantage over Spain lay not in mass, but in a superior energy, which gave them more rapid movement. Drake’s squadron, when he sailed round the world, numbered five ships, the largest measuring only one hundred and twenty tons, the smallest twelve, but with these he succeeded because of their speed. For example, he overtook the Cacafuego, whose ballast was silver, and whose cargo gold and jewels. He never disclosed her value, but the Spanish government afterward proved a loss of a million and a half of ducats, beside the property of private individuals. In like manner the Armada was destroyed by little ships, which sailed round their clumsy enemy, and disabled him before he could strike a blow in self-defence. The Spanish wars were halcyon days for the men of martial blood who had lost their land; they took to the sea by thousands, and ravaged the Spanish colonies with the energy and ferocity of vikings. For nearly a generation they wallowed in gold and silver and gems, and in the plunder of the American towns. Among these men Sir Francis Drake stood foremost, but, after 1560, the southern counties swarmed with pirates; and when, in 1585, Drake sailed on his raid against the West Indies, he led a force of volunteers twenty-five hundred strong. He held no commission, the crews of his twenty-five ships served without pay, they went as buccaneers to fatten on the commerce of the Spaniard. As it happened, this particular expedition failed financially, for the treasure fleet escaped, and the plunder of the three cities of Santiago, Saint Domingo, and Carthagena yielded only £60,000, but the injury done to Spain was incalculable.
