Where did the first battle in the American Revolution take place?

The first battle was fought at Lexington, where the so called 'shot heard around the world' was fired by an unknown gunman, beginning the first battle of the war. The British won this battle and marched on to Concord, where they were defeated and forced to retreat to Boston. On the way, they had to go back through Lexington, where the Revolvers were waiting to take revenge, causing another defeat for the British army.
