Answer:
The battles in Lexington, Concord, and Cambridge were significant because they marked the beginning of the American Revolution.
Step-by-step explanation:
These battles occurred on April 19, 1775 in the County of Middlesex, Massachusetts, in the villages from Lexington, Concord, Lincoln, Arlington and Cambridge, and supposed a point of no return that marked the beginning of War of Independence of the United States.
The British army, which was stationed in Boston, had received reports of an arms storehouse of the revolutionaries in Concord. The British made a plan to seize these weapons, but the plans leaked and the rebels moved their supplies to safe places. When a British army unit of 700 men set out for Concord on April 18 to seize the reported weapons, the seeker of the Old North Church hung two lanterns on the spire to warn the revolutionary Paul Revere. Revere borrowed a horse and rode with a number of comrades to Lexington at night to alert the local civilian militia. After delivering his message to Lexington, he drove toward Concord, but was arrested by a British patrol and taken prisoner.
After being warned by Revere, a group of about 77 Minutemen waited for the British unit on the common lawn in downtown Lexington. It is unclear who fired the first shot. The battle lasted only a few minutes, after which the revolutionaries were forced by the British force to withdraw. There were eight Americans dead and ten injured, and a British soldier was wounded. After the victory, British unity moved on to Concord in good spirits.
Also in Concord the revolutionaries were finally warned, and had taken a position to wait for the British at the "North Bridge" over the Concord River. This time the rebels managed to flee the British, and with that they inflicted the invincible British soldiers the first defeat in the British colonies in North America. The British moved back to Boston and were attacked by other Minutemen along the way. The experience that the Minutemen gained there would show that guerrilla warfare was the best strategy against the British for the settlers. The Battles of Lexington, Cambridge and Concord prompted 16,000 New Englanders to join the warring insurgents for a Boston siege.
