The Battle of Lexington and Concord was the first fight in the American Revolutionary War in 1775. British troops wanted to seize colonial weapons stored in Concord. In Lexington, the first shots were fired, marking the start of the war. Neither side wanted to shoot but a shot fires and it’s called the “shot heard around the world”. The colonists fought back, and as the British retreated from Concord, they faced constant attacks from local militia called minutemen.
