Why England Won The Siege Of Boston

After the Battles of Lexington and Concord, the militias pushed the British forces back into the city of Boston. The militias then set up camp around the city of Boston and attempted to place a siege on the city. However that did not affect the British in a concerning way, since they were still able to receive more troops and supplies from the harbor which the colonists could not blockade since they had virtually no naval based force. Although the British were not in major trouble of running out of supplies during the so called Siege of Boston, they were still stuck inside the city of Boston and faced at least some personnel and supply obstacles. England's leadership decided that it was best for the British to force their way out of Boston and make an impression on the rebellious colonists.

Action was taken on June 15, 1775 and a portion of men from the militias surrounding Boston crossed the Charles River to the Charlestown peninsula in order to capture Bunker Hill. This force included men from regiments commanded by Colonel Prescott, Colonel Frye, Colonel Bridge, around 200 men from the work party under Captain Knowlton, and an artillery company commanded by Captain Gridley. The combined forces were over 1000 men. Additional forces would also arrive throughout the fortification
