On the ground, fighting in the American Revolution began with the skirmishes between British regulars and American provincials on April 19, 1775, first at Lexington, where a British force of 700 faced 77 local minutemen, and then at Concord, where an American counterforce of 320 to 400 sent the British scurrying. The British had come to Concord to seize the military stores of the colonists, who had been forewarned of the raid through efficient lines of communication—including the ride of Paul Revere, which is celebrated with poetic license in Longfellow’s “Paul Revere’s Ride” (1861).
