For one thing, The Patriots took action on June 16, 1775 when Colonel William Prescott led 1,200 Patriot minutemen up Bunker Hill across the Charles River from Boston. Prescott wanted to use the hill to fire against British Ships in Boston Harbor.
WE'VE MADE IT SUCCESSFULLY UP BUNKER HILL, FINALLY!
Earlier Prescott then noticed that Breed's Hill was nearby and was an even better place to use the geography to his advantage, so then he ordered his soldiers to move there.
SOLDIERS, WE ARE MOVING TO BREED'S HILL. IT IS NEARBY AND IS BETTER TO USE THE GEOGRAPHY TO MY ADVANTAGE.
Then after seeing the Patriots march to Breed's Hill, The British General, William Howe, brought 2,400 redcoats. The first attempt to attack the Americans were unsuccessful, the British then were forced to retreat.
Afterward, as of the first British attack not being successful, the second attack from the British also went down. They retreated again.
Yes! The British had a second unsuccessful battle with us!
Soon the third try that the British have done, they managed to capture both Bunker Hill and Breed's Hill. They pushed over the top of the hill, and at the end of the battle more than 1,000 redcoats lay dead or wounded.
Lastly the American losses only numbered 400 men. The British had paid a high price for their victory. It was clear at the end of the battle that Americans could fight bravely, and also that the British would not be easy to defeat.
