Bunker Hill is the name of a battle fought near Boston, Massachusetts, on June 17th, 1775 between the Americans, led by Colonels Putnam and Prescott, and the British led by Generals Howe and Clinton.
The Battle of Bunker Hill is misnamed. The battle actually took place on Breed's Hill, not Bunker Hill.
The Americans repelled the first two attacks by the British, but were forced to retreat from the third attack when they ran out of ammunition.
The battle was a costly victory for the British who lost more than 40% of their force. Even though the Americans were defeated, it proved that the British could suffer great losses, too, giving encouragement to the growing rejection of British rule.
