The new city was by this time thoroughly cosmopolitan. One traveler speaks of the use of eighteen different languages, and the forms of faith were as varied as the tongues spoken. Seven or eight large ships came every year from Amsterdam. The Director occupied a fine house on the point of the island. On the east side of the town stood the Stadt-Huys protected by a half-moon of stone mounted with three small brass cannon. In the fort stood the Governor's house, the church, the barracks, the house for munitions, and the long-armed windmills. Everything was prospering except the foundation on which all depended. There was no adequate defense for all this property. Here we must acquit Stuyvesant from responsibility, since again and again he had warned the Company against the weakness of the colony; but they would not heed the warnings, and the consequences which might have been averted suddenly overtook the Dutch possessions.

The war which broke out in 1652 between England and the Netherlands, once leagued against Catholic Spain but now parted by commercial rivalries, found an immediate echo on the shores of the Hudson. With feverish haste the inhabitants of New Amsterdam began to fortify. Across the island at the northern limit of the town, on the line of what is now Wall Street, they built a wall with stout palisades backed by earthworks. They hastily repaired the fort, organized the citizens as far as possible to resist attack, and also strengthened Fort Orange. The New England Colonies likewise began warlike preparations; but, perhaps owing to the prudence of Stuyvesant in accepting the Treaty of Hartford, peace between the Dutch and English in the New World continued for the present, though on precarious terms; and, the immediate threat of danger being removed by the treaty between England and Holland in 1654, the New Netherlander relaxed their vigilance and curtailed the expense of fortifications.

Meanwhile Stuyvesant had alienated popular sympathy and lessened united support by his treatment of a convention of delegates from New Amsterdam, Flushing, Breuckelen, Hempstead, Amersfort, Middleburgh, Flatbush, and Gravesend who had gathered to consider the defense and welfare of the colonies. The English of the Long Island towns were the prime movers in this significant gathering. There is an unmistakable English flavor in the contention of The Humble Remonstrance adopted by the Convention, that "'tis contrary to the first intentions and genuine principles of every well regulated government, that one or more men should arrogate to themselves the exclusive power to dispose, at will, of the life and property of any individual." As a people "not conquered or subjugated, but settled here on a mutual covenant and contract entered into with the Lord Patroons, with the consent of the Natives," they protested against the enactment of laws and the appointment of magistrates without their consent or that of their representatives.

Stuyvesant replied with his usual bigotry and in a rage at being contradicted. He asserted that there was little wisdom to be expected from popular election when naturally "each would vote for one of his own stamp, the thief for a thief, the rogue, the tippler and the smuggler for his brother in iniquity, so that he may enjoy more latitude in vice and fraud." Finally Stuyvesant ordered the delegates to disperse, declaring: "We derive our authority from God and the Company, not from a few ignorant subjects, and we alone can call the inhabitants together."

With popular support thus alienated and with appeals for financial and military aid from the States-General and the West India Company denied or ignored, the end of New Netherland was clearly in sight. In 1663 Stuyvesant wrote to the Company begging them to send him reënforcements. "Otherwise," he said, "it is wholly out of our power to keep the sinking ship afloat any longer."

This year was full of omens. The valley of the Hudson was shaken by an earthquake followed by an overflow of the river, which ruined the crops. Smallpox visited the colony, and on top of all these calamities came the appalling Indian massacre at Esopus. The following year, 1664, brought the arrival of the English fleet, the declaration of war, and the surrender of the Dutch Province. For many years the English had protested against the Dutch claims to the territory on the North and South rivers. Their navigators had tried to contest the trade in furs, and their Government at home had interfered with vessels sailing to and from New Amsterdam. Now at length Charles II was ready to appropriate the Dutch possessions. He did not trouble himself with questions of international law, still less with international ethics; but, armed with the flimsy pretense that Cabot's visit established England's claim to the territory, he stealthily made preparations to seize the defenseless colony on the river which had begun to be known as the Hudson. Five hundred veteran troops were embarked on four ships, under command of Colonel Richard Nicolls, and sailed on their expedition of conquest. Stuyvesant's suspicions, aroused by rumors of invasion, were so far lulled by dispatches from Holland that he allowed several ships at New Amsterdam to sail for Curaçao ladened with provisions, while he himself journeyed to Rensselaerswyck to quell an Indian outbreak. While he was occupied in this task, a messenger arrived to inform him that the English fleet was hourly expected in the harbor of New Amsterdam. Stuyvesant made haste down the river; but on the day after he arrived at Manhattan Island, he saw ships flying the flag of England in the lower harbor, where they anchored below the Narrows. Colonel Nicolls demanded the surrender of the "towns situate on the island commonly known by the name of Manhattoes, with all the forts thereunto belonging."

Although the case of New Amsterdam was now hopeless, Stuyvesant yet strove for delay. He sent a deputation to Nicolls to carry on a parley; but Nicolls was firm. "When may we visit you again?" the deputation asked. Nicolls replied with grim humor that he would speak with them at Manhattan. "Friends are welcome there," answered Stuyvesant's representative diplomatically; but Nicolls told them bluntly that he was coming with ships and soldiers. "Hoist a white flag at the fort," he said, "and I may consider your proposals."

Colonel Nicolls was as good as his word and, to the consternation of the dwellers in New Amsterdam, the fleet of English frigates, under full sail and with all guns loaded, appeared before the walls of the useless old Fort Amsterdam. Stuyvesant stood on one of the angles of the fort and the gunners with lighted matches awaited his command to fire. The people entreated him to yield. "Resistance is not soldiership," said one of them. "It is sheer madness." Stuyvesant, who with all his faults was a brave soldier, felt to the quick the humiliation; but he saw also that resistance meant only useless bloodshed. At last he submitted, and the English vessels sailed on their way unmolested, while Stuyvesant groaned, "I would much rather be carried to my grave."

Without firing a shot the English thus took possession of the rich country which the States-General had not thought worth defending, and New Netherland became New York.
