Revere to warn Patriot militia of an imminent attack by the British Army on the night before the Battles of Lexington and Concord in April 1775. Longfellow's poem was first published in the January 1861 issue of The Atlantic Monthly and later included as part of Longfellow's 1863 poetry collection Tales of a Wayside Inn. Ralph Waldo Emerson's 1837 poem Concord Hymn pays tribute to the Patriot militia at the Battle of Concord and famously says that they fired, "The shot heard round the world." David Humphreys wrote the first sonnet in American poetry in 1776, right before he left Yale College to fight as a colonel in the Continental Army during the American Revolutionary War. Colonel Humphreys' sonnet was titled Addressed to my Friends at Yale College, on my leaving them to join the Army.

In the poem, Iain mac Mhurchaidh called the American Revolution against King George every bit as unnatural as disrespect against one's earthly or heavenly father. He also threatened that Patriots who did not submit to the British Monarchy would be treated like both real and suspected Jacobites had been treated in the aftermath of the Battle of Culloden, which is still referred to in the Highlands and Islands as Bliadhna nan Creach ("The Year of the Pillaging"). In may well have been in retaliation for this very poem that, according to one
