1775 – American Revolution: The British advancement by sea begins; Paul Revere and other riders warn the countryside of the troop movements
. Paul Revere (December 21, 1734 O.S. – May 10, 1818) was an American silversmith, engraver, early industrialist, and a patriot in the American Revolution. He is most famous for alerting the Colonial militia to the approach of British forces before the battles of Lexington and Concord, as dramatized in Henry Wadsworth Longfellow's poem, "Paul Revere's Ride." Revere was a prosperous and prominent Boston silversmith, who helped organize an intelligence and alarm system to keep watch on the British military. Revere later served as a Massachusetts militia officer, though his service culminated after the Penobscot Expedition, one of the most disastrous campaigns of the American Revolutionary War, for which he was absolved of blame. Following the war, Revere returned to his silversmith trade and used the profits from his expanding business to finance his work in iron casting, bronze bell and cannon casting, and the forging of copper bolts and spikes. Finally in 1800 he became the first American to successfully roll copper into sheets for use as sheathing on naval vessels.
