Answer:
At Lexington Green, the British were met by approximately seventy American Minute Men led by John Parker. At the North Bridge in Concord, the British were confronted again, this time by 300 to 400 armed colonists, and were forced to march back to Boston with the Americans firing on them all the way.The Battles of Lexington and Concord on 19 April 1775, the famous 'shot heard 'round the world', marked the start of the American War of Independence (1775-83). Politically disastrous for the British, it persuaded many Americans to take up arms and support the cause of independence.
