Claiborne's first appeal to royal authority in the dispute, which complained both that the lands in the Maryland charter were not really unsettled, as the charter claimed, and that the charter gave so much power to Calvert that it undermined the rights of the settlers, was rejected by the Lords of Foreign Plantations in July 1633. The following year, the main body of Calvert's settlers arrived in the Chesapeake and established a permanent settlement on Yaocomico lands at St. Mary's City. With the support of the Virginia establishment, Claiborne made clear to Calvert that his allegiance was to Virginia and royal authority, and not to the proprietary authority in Maryland. Some historical reports claim that Claiborne tried to incite the natives against the Maryland colonists by telling them that the settlers at St. Mary's were actually Spanish and enemies of the English, although this claim has never been proven. In 1635, a Maryland commissioner named Thomas Cornwallis swept the Chesapeake for illegal traders and captured one of Claiborne's pinnaces in the Pocomoke Sound. Claiborne tried to recover it by force, but was defeated; although he retained his settlement on Kent Island. These were the first naval battles in North American waters, on 23 April and 10 May 1635; three Virginians were killed.
