Notwithstanding the remonstrance of the court at New Haven, their appeal to King Charles II., and the engagements of Governor Winthrop, Connecticut pursued the affair of a union in the same manner in which it was begun. At a session of the General Assembly, August 19, 1663, a committee was again appointed to treat with their friends at New Haven, Milford, Guilford, and Branford, relative to their incorporation with Connecticut. Provided they could not effect a union by treaty, they were authorized to read the Charter publicly at New Haven, and to make declaration to the people there that the Assembly could not but resent their proceedings as a distinct jurisdiction, since they were evidently included within the limits of the Charter granted to the corporation of Connecticut. They were instructed to proclaim that the Assembly did desire, and could not but expect, that the inhabitants of the above towns would yield subjection to the government of Connecticut.

At a meeting of the commissioners in September in the same year, New Haven was owned by the colonies as a distinct confederation. Governor Leet and Mr. Fenn, who had been sent from that jurisdiction, exhibited a complaint against Connecticut for the injuries they had done, by encroaching upon their rights, receiving their members under their government, and encouraging them to disown their authority, to disregard their oath of allegiance, and to refuse all attendance on their courts. They further complained that Connecticut had appointed constables in several of their towns, to the great disquiet and injury of the colony. They prayed that effectual measures might be taken to redress their grievances, to prevent further injuries, and secure their rights as a distinct confederation.

Governor Winthrop and Mr. John Talcott, commissioners from Connecticut, replied that, in their opinion, New Haven had no just grounds of complaint; that Connecticut had never designed them any injury, but had made to them the most friendly propositions, inviting them to share with them freely in all the important and distinguishing privileges which they had obtained for themselves; that they had sent committees amicably to treat with them; that they were still treating, and would attend all just and friendly means of accommodation.

The commissioners of the other colonies, having fully heard the parties, determined that “where any act of power had been exerted against the authority of New Haven, the same ought to be recalled, and their power reserved to them entire, until such time as, in an orderly way, it shall be otherwise disposed.” With respect to the particular grievances mentioned by the commissioners of New Haven, the consideration of them was referred to the next meeting of the commissioners at Hartford.

In this situation of affairs an event took place which alarmed all the New England colonies, and at once changed the opinion of the commissioners, and of New Haven, with respect to their incorporation with Connecticut.

King Charles II., on the 12th of March, 1664, gave a patent to his brother, the Duke of York and Albany, of several extensive tracts of land in North America, the boundaries of which are thus described:

“All that part of the main land of New-England, beginning at a certain place called and known by the name of St. Croix, next adjoining to New-England, in America, and from thence extending along the sea-coast into a certain place called Pemaquie, or Pemaquid, and so up the river thereof to the furthest head of the same, as it tendeth northward, and from thence extending to the river Hembequin, and so upward, by the shortest course, to the river Canada northward; and also all that island or islands commonly called by the general name or names of Meitowax, or Long-Island, situate and being toward the west of Cape Cod, and the narrow Highgansets abutting on the main land, between the two rivers, these called and known by the several names of Connecticut and Hudson’s Rivers; and all the land on the west side of Connecticut River, to the east side of the Delaware-Bay; and also all those several islands called or known by the names of Martin’s Vineyard, or Nantucks, otherwise Nantucket: together,” etc., etc.

The concern of the Duke of York for his property, and the aversion both he and his Majesty had for the Dutch, led them to dispatch an army and fleet to New England for the reduction of the Dutch settlement on the continent. Colonel Richard Nichols was chief commander of the fleet and army. Sir Robert Carr, George Cartwirth, and Samuel Maverick, Esq., were appointed commissioners with him, to determine all matters of complaint and controversy, and settling the country in peace.

Colonel Nichols arrived in Boston, with the fleet and troops under his command, on the 23d of July, 1664. He then sailed for the New Netherlands on the 20th of August, and made a demand of the town and forts upon the island of Manhadoes. Governor Winthrop, and several magistrates and principal gentlemen of Connecticut, joined him at the west end of Long Island, according to his request.

Stuyvesant, the Dutch Governor, was an old soldier, and, had he been better prepared and the people united, doubtless could have made a brave defense. But he had no intimations of the design until the 8th of July, when he received intelligence that a fleet of three or four ships of war, with three hundred and fifty soldiers on board, were about to sail from England against the Dutch settlements. Upon this he immediately ordered that the forts should be put in a state of defense, and sent out spies into several parts of Connecticut for further information. It has been said that the Dutch Governor was negotiating a neutrality with Connecticut when he received the news of the fleet’s arrival in Boston. Stuyvesant was extremely opposed to a surrender of the fort and town. Instead of submitting to the summons at first sent him, he drew up a long statement of the Dutch claims, and their indubitable right to the country. He insisted that, had the king of England known the justice of their claims, he never would have adopted such measures against them. He concluded by assuring Colonel Nichols that he should not submit to his demands, nor fear any evils but such as God in his providence should inflict upon him.
