The patriots of the American Revolution fought their first open military engagement at the Lexington and Concord battleground near Boston, Mass. The battle took place on April 19, 1775.
The Lexington and Concord battleground was comprised of several Boston-area towns: Lexington, Concord, Lincoln, Menotomy and Cambridge. The patriots were members of the Massachusetts militia, which represented the 13 colonies of British North America. They battled the kingdom of Great Britain and were fighting to gain autonomy as an independent nation. The battle was deemed a patriot victory, as the British soldiers were outnumbered and forced to retreat back to Boston.
