The incident at the North Bridge later was memorialized by Ralph Waldo Emerson in his 1837 poem “Concord Hymn,” whose opening stanza is: “By the rude bridge that arched the flood/Their flag to April’s breeze unfurled/Here once the embattled farmers stood/And fired the shot heard round the world.” Emerson penned “Concord Hymn” for the dedication of a battle monument at the site of the North Bridge. At the dedication ceremony on July 4, 1837, a group of townspeople sang the poem’s 16 lines to the tune of a traditional hymn called “Old Hundredth.”
