The Battle of Bunker Hill was fought on June 17th, 1775. American colonists were surrounding Boston which at the time was full of British troops. Across the Charles River from Boston was the Charlestown Peninsula where the town of Charlestown and Breed's Hill, as well as Bunker's Hill, were located. A few days before the 17th, the colonists received word the British would attempt to try to break out of Boston, and they sent 1200 men under the command of William Prescott into the quiet of the night and built fortifications on those two hills. It's there that it's rumored the first continental flag was flown.
