April 18, 1775 - General Gage orders 700 British soldiers to Concord to destroy the colonists' weapons depot.
That night, Paul Revere and William Dawes are sent from Boston to warn colonists. Revere reaches Lexington about midnight and warns Sam Adams and John Hancock who are hiding out there.
At dawn on April 19 about 70 armed Massachusetts militiamen stand face to face on Lexington Green with the British advance guard. An unordered 'shot heard around the world' begins the American Revolution. A volley of British muskets followed by a charge with bayonets leaves eight Americans dead and ten wounded. The British regroup and head for the depot in Concord, destroying the colonists' weapons and supplies. At the North Bridge in Concord, a British platoon is attacked by militiamen, with 14 casualties.
No taxation without representation" is a slogan originating during the 1750s and 1760s that summarized a primary grievance of the British colonists in the Thirteen Colonies, which was one of the major causes of the American Revolution. In short, many in those colonies believed that as they were not directly represented in the distant British Parliament, any laws it passed taxing the colonists (such as the Sugar Act and the Stamp Act) were illegal under the Bill of Rights 1689, and were a denial of their rights as Englishmen
The American Revolution (1775-83) is also known as the American Revolutionary War and the U.S. War of Independence. The conflict arose from growing tensions between residents of Great Britain's 13 North American colonies and the colonial government, which represented the British crown.
Skirmishes between British troops and colonial militiamen in Lexington and Concord in April 1775 kicked off the armed conflict, and by the following summer, the rebels were waging a full-scale war for their independence.
France entered the American Revolution on the side of the colonists in 1778, turning what had essentially been a civil war into an international conflict. After French assistance helped the Continental Army force the British surrender at Yorktown, Virginia, in 1779, the Americans had effectively won their independence, though fighting would not formally end until 1783.
