History of the State of New York, Vol. I (1609-1691)
The English lay claim to the South river against which the Dutch Governor warmly protested, but the English have answered that they should persist in, and retain possession of what they claim. In fine, it looks as if everything would shortly be English, for experience shows that the boundary line four leagues west of Greenwich encroaches as it goes into the interior of the country and that the English will in a short time be in the neighborhood of Fort Orange and the trade. The Dutch Governor is absolutely stripped of the Fresh river and New Haven, especially and particularly of New Haven, on which he declares he has not, nor ever had, any pretensions. And then his former various protests and menaces were read to him, and among the rest, his letter that the blood should be on their own heads, which he denied, saying: that such was an error of his Secretary. The English will not trouble him, at present, respecting the capture of Westenhuysen's ship which lay at New Haven and was confiscated by the Dutch Governor, as he has requested, and obtained from the English Commissioners, permission to pass and repass. But time will tell what circumstances will bring about on the next opportunity, for the Commissioners have given Weslenhuysen a writing under their hand that the Dutch Governor has not, and never had any claim to New Haven. Moreover, at the meeting of the Colonies a firm alliance was entered into between both Nations, the English and the Dutch, to the effect that they shall help to defend each other, as good neighbors, against all enemies, and mutually entertain good correspondence and trade, the Indian trade excepted, which remains unchanged; also, the Dutch governor shall be at liberty to assist at the meetings of the Commissioners.
