What happened on Lexington Green on April 19, 1775?Who fired the shot that began the American Revolution?

On April 19, 1775, the Battle of Lexington and Concord marked the first military 

engagement of the American Revolution. Colonists had gathered in the early morning on 

Lexington Green to prevent approaching British troops from destroying guns and ammunition 

that were stored in nearby Concord. The gathered faction of colonists was ordered by the British 

to disperse when “the shot heard ‘round the world” was fired and the American Revolution 

began. Ralph Waldo Emerson wrote that immortal line in his 1837 Concord Hymn, but what is

perhaps most intriguing about that fateful shot is that no one knows for sure who fired it.
