April 19, 1775

The shot heard around the world.

Think "Bridge".

"Patriot's Day"

"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. According to Emerson's poem, this pivotal shot occurred at the Old North Bridge in Concord, Massachusetts, where the first British soldiers fell in the battles of Lexington and Concord.

Historically, no single shot can be cited as the first shot of the battle or the war. Shots were fired earlier at Lexington, Massachusetts where eight Americans were killed and a British soldier was slightly wounded, but accounts of that event are confused and contradictory, and it has been characterized as a massacre rather than a battle.[1] The North Bridge skirmish did see the first shots by Americans acting under orders, the first organized volley by Americans, the first British fatalities, and the first British retreat.

The towns of Lexington and Concord and their partisans have debated over the point of origin for the Revolutionary War since 1824, when the Marquis de Lafayette visited the towns. He was welcomed to Lexington hearing it described as the "birthplace of American liberty", but he was then informed in Concord that the "first forcible resistance" was made there. President Grant considered not attending the 1875 centennial celebrations in the area to evade the issue. In 1894, Lexington petitioned the state legislature to proclaim April 19 as "Lexington Day", to which Concord objected; the current name for the holiday is Patriots' Day."
