The Powder Alarm is a major popular reaction to the removal of gunpowder from a magazine by British soldiers under orders from General Thomas Gage, royal governor of the Province of Massachusetts Bay, on September 1, 1774.
In response to this action, amid rumors that blood has been shed, alarm spread through the countryside to Connecticut and beyond, and American Patriots spring into action, fearing that war is at hand
Thousands of militiamen begin streaming toward Boston and Cambridge, and mob action forces Loyalists and some government officials to flee to the protection of the British Army.
Although it proves to be a false alarm, the Powder Alarm causes political and military leaders to proceed more carefully in the days ahead, and essentially provides a "dress rehearsal" for the Battles of Lexington and Concord seven and a half months later.
Furthermore, actions on both sides to control weaponry, gunpowder, and other military supplies become more contentious, as the British seek to bring military stores more directly under their control, and the Patriot colonists seek to acquire them for their own use.
