The commissioners acted with prudence and good sense. They did not proceed at once to Jamestown, but first issued a proclamation intended to disabuse the people of any idea that they came to make war.[37] The result was that in March, 1652, when they appeared before the little capital, the council and burgesses overruled Berkeley, and entered into an agreement with Curtis, Claiborne, and Bennett, which proves the absence of hard feelings on both sides. The Virginians recognized the authority of the commonwealth of England, and promised to pass no statute contrary to the laws of Parliament. On the other hand, the commissioners acknowledged the submission of Virginia, "as a voluntary act not forced nor constrained by a conquest upon the countrey"; and conceded her right "to be free from all taxes, customs, and impositions whatever, not enforced by the General Assembly." In particular it was stipulated that "Virginia should have and enjoy the antient bounds and lymitts granted by the charters of the former kings." The articles were signed March 12, 1652, and the commissioners soon after sailed to St. Mary's and received the surrender of Maryland. They returned in time to be present at a new meeting of the assembly held at Jamestown in April, at which it was unanimously voted that until the further pleasure of Parliament was known Richard Bennett should be governor and William Claiborne secretary of state. To the burgesses, as the representatives of the people, was handed over the supreme power of thereafter electing all officers of the colony.[38] Then Virginia, the last of the British dominions to abandon the king, entered upon eight years of almost complete self-government, under the protection of the commonwealth of England. In 1652 the settlements in Virginia were embraced in thirteen counties, of which Northampton, on the Accomack Peninsula, extended to the southern boundary of Maryland. On the James River were nine counties: Henrico, Charles City, James City, Surry, Warwick, Warascoyack, or Isle of Wight, Elizabeth City, Nansemond, and Lower Norfolk. On York River were York County on the south side and Gloucester on the north side.[39] On the Rappahannock was Lancaster County, extending on both sides of the river from Pianketank to Dividing Creek in the Northern Neck; and on the Potomac was the county of Northumberland, first settled about 1638 at Chicacoan and Appomattox on the Potomac, by refugees from Maryland.[40] Towards the south the plantations, following the watercourses, had spread to the heads of the creeks and rivers, tributaries of the James, and some persons more adventurous than the rest had even made explorations in North Carolina.[41] Westward the extension was, of course, greatest along the line of the James, reaching as far as the Falls where Richmond now stands. The population was probably about twenty thousand, of whom as many as five thousand were white servants and five hundred were negroes.
