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.
This action sparked local unrest, and militia companies began mustering throughout the colony. Patrick Henry led a small militia force toward Williamsburg to force return of the gunpowder to the colony's control. The matter was resolved without conflict when a payment of £330 was made to Henry. Dunmore, fearing for his personal safety, later retreated to a naval vessel, ending royal control of the colony.
Military tensions began to rise in the British colonies of North America in 1774 when a series of legislative acts by the British Parliament known as the Intolerable Acts began to be implemented in the colonies. The colonies, in solidarity with the Province of Massachusetts Bay, which had been singled out for punishment by those acts in the wake of the Boston Tea Party, had organized a Congress to meet in September 1774. During the meeting of the First Continental Congress word arrived of a militia uprising in Massachusetts that became known as the Powder Alarm. In early September, General Thomas Gage, the royal governor of Massachusetts, had removed gunpowder from a powder magazine in Charlestown (in a location now in Somerville), and militia from all over New England had flocked to the area in response to false rumors that violence had been involved. One consequence of this action was that the Congress called for the colonies to organize militia companies for their defense. Another was that Lord Dartmouth, the Secretary of State for the Colonies, advised the colonial governors to secure their military supplies, and prohibited importation of further supplies of powder.
