Dunmore threatened to impose martial law, and eventually retreated to Porto Bello to join his family. Dislodged by the Virginia rebels and wounded in the leg,[9] on 8 June, Dunmore took refuge on the British warship HMS Fowey in the York River. Over the next months, Dunmore sent many raiding parties to plunder plantations along the James, York and Potomac rivers, particularly those owned by rebels.
