When Nicolls assumed control as Governor of New Amsterdam, under the patent to the Duke of York, he considered it best to act in a liberal spirit toward the Dutch, and endeavored to gain their good will and esteem. Indeed, this was the wise English policy which he represented. So conciliatory was his administration that the Dutch element did not appear to be affected by the change. The trade with Holland was continued without interruption. The Dutch were permitted to elect all minor officials and to observe the customs of the fatherland. New York received a new charter, and the government was placed in the hands of a Mayor, Aldermen, and Sheriff, appointed by the Governor. The legislative power was vested in the Governor and Council, who alone possessed the power to impose taxes.

The titles to property in the province were not in any way disturbed. The Council was careful to confirm and declare legal all grants, patents, and other evidences of title which had been derived through the Dutch government. New grants in confirmation were given, and additional expense in consequence was imposed upon the owners. Large sums were also expended in repairing the forts in and about the harbor to resist any attempt which might be made to retake the city.

Measures were also adopted to provide a more perfect and uniform system for the government of the towns on Long Island. In order to reconcile differences, and establish laws which should control in each town, Nicolls organized an Assembly of delegates, composed of representatives from each town. The Assembly thus formed, met in Hempstead in 1665. Breuckelen was represented in that body by two of her well-known citizens, in the persons of Frederick Lubbertsen and Evertsen Bout. The Assembly adopted a code of laws which were called the "Duke's Laws." Considering the state of the times and the varied conditions of the people, the code thus adopted was reasonable and just to all. These laws continued in operation with slight amendments until 1683, when Governor Dongan convened his provincial Assembly. The actions of Governor Nicolls gave the delegates satisfaction and pleasure, and they became his fast friends. They expressed their admiration of his actions by an address of congratulation to the Duke of York, which was characterized by an exceedingly deferential tone toward the new authority. Many of the people objected to the tone of this address, and gave vent to their feelings in outspoken language against the delegates. So fearless and indiscreet was the language used, and so imminent did the violence threatened by the anti-English element appear, that the Government was constrained to take notice of the same. At a court held in 1666, a stringent act was passed to prevent a repetition of the slanders against the delegates.

In 1665, Long Island, with Staten Island, was created a shire, and called Yorkshire, as a token of respect to the proprietor, the Duke of York. The shire thus formed was divided into districts, which were denominated ridings. The towns included in Kings County, Staten Island, and Newtown, were called the West Riding. Nicolls displayed much wisdom in the management of the colony, and thereby won the respect of the people. He did not, however, remain long in service. Being anxious to return to Europe, in 1668 he bade farewell to the New World, and set his face eastward. Upon his return to his native land he engaged in his country's service in the war with Holland, and gave his life in defending the flag in a naval engagement in 1692.

Nicolls was succeeded by Governor Francis Lovelace, whose administration was a striking contrast to that of his predecessor. Despotic, arrogant, and self-willed, Lovelace was born to be a "paternal" ruler, and ever manifested a domineering spirit. The inhabitants had always claimed the right to levy and impose their own taxes, and protested against taxation without representation. To all protests he paid no attention except to "pronounce their complaints as scandalous and seditious." His frequent remark was, "the people should have liberty for no thought but how to pay their taxes." In order to carry out his views, and to display his power, he imposed a duty of ten per cent. upon all imports and exports arriving at or going from the province.

In 1672, Charles II., instigated by the French, proclaimed war against Holland. This rupture led the Dutch to conceive the idea of regaining their lost possessions. A squadron consisting of five vessels was fitted out, and placed under the command of Admirals Beuckes and Evertson. The fleet thus prepared sailed from Holland and appeared off Sandy Hook on the 29th of July, 1673. The news of the expedition reached the city long before the arrival of the fleet. Governor Lovelace had no adequate idea of the importance and necessity of preparation to resist the attack. He left the city and proceeded to Albany to regulate the difficulties with the Indians, and placed the fort in charge of Captain Manning. When the news reached the city that the Dutch fleet was approaching, Manning sent messengers to Governor Lovelace, requesting him to return speedily. He came, and at once commenced active defensive preparations. The fort was manned, and soldiers were mustered into service and drilled. The enemy not appearing, the Governor disbanded his forces and went to Connecticut. When the fleet reached Sandy Hook, Manning again informed the Governor and requested him to return, and in the mean time employed himself in collecting recruits. He was not successful. The love of fatherland could not be obliterated from the hearts of Dutchmen. They refused to volunteer against their own flesh and blood, and instead spiked the guns of the fort to prevent any resistance to the fleet. The soldiers in the fort were but amateurs, and having had no experience were of but little service. The fleet anchored in New York Bay, July 30, 1673.

Manning lacked courage, and did not possess any attribute fitting him to properly defend the city. In his dilemma, and not having the aid and assistance of the Governor, he found himself powerless to act as the occasion demanded. He sent a messenger to the fleet to inquire their object in disturbing the peace of the colony. In the morning, the admirals dispatched an officer to demand the immediate surrender of the fort. Manning, anxious to gain time, requested that he might have until the following day to give his answer. This was refused, and he was notified that unless the city was surrendered in half an hour the fort would be bombarded. To this notification no reply was received. The Dutch, true to their word, commenced a cannonade which resulted in killing and wounding a number of men. The salute of hot shot was not returned. Captain Colve, with a band of six hundred men, landed, and the attacking force was ranged in line of battle in front of the fort, and prepared to make a triumphal march through the city. Manning became agitated and frightened. He commenced negotiations, but, as he had no power to enter into any agreement, he was compelled to surrender.

The city, again in the possession of its original settlers, was called New Orange, and the fort was named Fort Hendrick. Some of the English soldiers taken as hostages of war were sent to Holland.

It may well be supposed that this successful capture produced a deep sense of mortification to the English Government and the New England colonies. Manning was subsequently court-martialed and tried for cowardice and treachery. His defense was mainly that he had no time to put the fort in a proper condition of defense—that the enemy were eight hundred strong, while he had but eighty men in the fort, and that he sought to delay capitulation, hoping that help might arrive. He was found guilty by the court. Through the influence of friends his life was spared, but he was compelled to suffer the ignominy of having his sword broken over his head by the executioner in front of the City Hall, and he was declared incapable of ever holding any office, either civil or military, in the gift of the Crown. Governor Lovelace also was severely reprimanded, and all his property was confiscated to the Duke of York. It would appear that the conduct of the Governor was more reprehensible than that of Manning. Manning was merely a subaltern, and Lovelace being Governor, it was his duty to exercise proper care in defending the territory committed to his control. He was twice notified by Manning of the intended attack, and seemed by his actions either to manifest but little interest, or not to realize the importance of defensive measures.

Captain Colve now assumed control of public affairs. Fearing that the English might endeavor to regain the territory, he repaired and strengthened the fort, and put the city under military protection. A new charter was given to the city, and the old forms of government readopted. Courts were established at various points, and all the magistrates were required to appear at New Orange, and swear allegiance to the Dutch Government.
