Explanation:

The phrase comes from the opening stanza of Ralph Waldo Emerson's "Concord Hymn" (1837) and refers to the first shot of the American Revolution at the Old North Bridge in Concord, Massachusetts, where the first British soldiers fell in the battles of Lexington and Concord on April 19, 1775. The phrase indicates that the shots fired at British troops during the Battle of Concord marked America's first victory against the powerful British army, which in turn sparked the Revolutionary War and lead to America's independence.
