Bunker Hill, Battle of at English => English (The Britannica Concise) Of Explained:
Important colonial victory early in the Amer. Revolution. Two months after the battles of Lexington and Concord, over 15,000 colonial troops assembled near Boston to stop the British army from occupying several hills around the city. The colonists fortified Bunker Hill (orig. Breed's Hill) across the Charles River from Boston; they withstood a cannonade from British ships in Boston Harbor on June 17, 1775, and also fought off assaults by 2,300 British troops, but were eventually forced to retreat. British casualties (about 1,000) and the colonists' fierce resistance convinced the British that subduing the rebels would be difficult.
