Question: Who may have been present at the battle that led to the departure of Royal Governor Lord Dunmore?

Context paragraphs:
Richard Parker (colonel): Richard Parker (1751 – 8 May 1780) was an American colonel who fought in the American Revolutionary War.  Son of prominent Virginia jurist Richard Parker, Parker received an officer's commission in a Virginia regiment early in the conflict.  He probably was present at Great Bridge and Norfolk.  Promoted to major, he fought at Trenton in December 1776 and commanded the regiment at Second Trenton and Princeton in January 1777.  At Brandywine in September 1777 he led a detachment of light infantry in delaying the British.  The next month he fought at Germantown.  Promoted to colonel at Valley Forge, he led a picked detachment at Monmouth in June 1778.  In May 1779, George Washington ordered him back to Virginia to recruit a new regiment.  After being sent south with a new unit of reinforcements for Charleston, South Carolina in late 1779, he died of wounds received at the Siege of Charleston in 1780.

Porto Bello (Williamsburg, Virginia): Porto Bello was the hunting lodge of the last Royal Governor of the British Colony of Virginia, John Murray, 4th Earl of Dunmore.  The name commemorates the battle of Porto Bello, a 1739 British naval victory in Panama.  Lord Dunmore fled to Porto Bello to escape the early stages of the American Revolution in Williamsburg, Virginia.  He later boarded a British ship lying at anchor near Porto Bello in the York River.

Battle of Point Pleasant: The Battle of Point Pleasant — known as the Battle of Kanawha in some older accounts — was the only major action of Dunmore's War.  It was fought on October 10, 1774, primarily between Virginia militia and Indians from the Shawnee and Mingo tribes.  Along the Ohio River near modern Point Pleasant, West Virginia, Indians under the Shawnee Chief Cornstalk attacked Virginia militia under Colonel Andrew Lewis, hoping to halt Lewis's advance into the Ohio Valley.  After a long and furious battle, Cornstalk retreated.  After the battle, the Virginians, along with a second force led by Lord Dunmore, the Royal Governor of Virginia, marched into the Ohio Valley and compelled Cornstalk to agree to a treaty, ending the war.

Battle of Great Bridge: The Battle of Great Bridge was fought December 9, 1775, in the area of Great Bridge, Virginia, early in the American Revolutionary War.  The victory by colonial Virginia militia forces led to the departure of Royal Governor Lord Dunmore and any remaining vestiges of British power over the Colony of Virginia during the early days of the conflict.

HMS Fowey (1749): HMS "Fowey" was a sixth-rate warship of the Royal Navy.  Built in 1749, the ship was sunk during the Siege of Yorktown in 1781.  The ship is noted as having received Lord Dunmore, the governor of the Colony of Virginia, when he fled the colony for safety during the beginning of the American Revolution, marking the last departure of a Royal Governor from the colony.  The National Park Service has identified it as a probably candidate for a wreck located off Yorktown in the York River.

Fort Charlotte (Nassau): Fort Charlotte is a British-colonial era fort built on a hill over-looking the harbor of Nassau, The Bahamas.  The fort sits a short walk west of downtown Nassau and the cruise ship terminal.  The fort was constructed in the late 18th century by British colonial governor Lord Dunmore after the end of the American Revolutionary war.  The fort has never been used in battle.  It is one of several English forts that are still standing in Nassau.  These forts were used as battle stations, to attack the invading Spaniards.

Ethiopian Regiment: Lord Dunmore's Ethiopian Regiment or Ethiopian Regiment was the name given to a British colonial military unit organized during the American Revolution by John Murray, 4th Earl of Dunmore, and last Royal Governor of Virginia.  It has nothing to do with the present day country of Ethiopia.  Composed of slaves who had escaped from Patriot masters, it was led by British officers and sergeants. Black Loyalists also served in guerrilla units such as the elite Black Brigade, as well as together with British troops and white Loyalist militia recruited in the colonies.

Fort Cricket Hill: Fort Cricket Hill is an historic American Revolutionary War site in Mathews County, Virginia.  The site is located near the Gwynn's Island bridge, which carries Cricket Hill Road (Virginia Route 223) to the island from the mainland near the village of Cricket Hill.  From fortifications on this site (now marked by a plaque and observation deck), rebel Patriot forces fired on British forces controlled by the royal governor, Lord Dunmore, that had occupied Gwynn's Island.

Gunpowder Incident: The Gunpowder Incident (or Gunpowder Affair) was a conflict early in the American Revolutionary War between Lord Dunmore, the Royal Governor of the Colony of Virginia, and militia led by Patrick Henry.  On April 20, 1775, one day after the Battles of Lexington and Concord (and well before news of that event reached Virginia), Lord Dunmore ordered the removal of the gunpowder from the magazine in Williamsburg, Virginia to a Royal Navy ship.

Fort Henry (West Virginia): Fort Henry was a fort which stood about ¼ mile from the Ohio River in what is now downtown, Wheeling, West Virginia.  The fort was originally known as Fort Fincastle and was named for Viscount Fincastle, Lord Dunmore, Royal Governor of Virginia.  Later it was renamed for Patrick Henry, and was at the time located in Virginia.  The fort was subject to two major sieges, two notable feats (McColloch's Leap and Betty Zane's trek through the battle) and other skirmishes.
