"The Star-Spangled Banner" is the United States national anthem, based upon the poem "Defence of Fort McHenry" by Francis Scott Key (1779-1843), commemorating a key part of the Anglo-American War of 1812 (1812-1815). In the now rarely-sung third verse of the anthem, which fell out of use after 1917 when the United States joined World War One (1914-1918) allied to Great Britain, the poem seems to mock Great Britain's implied hope to destroy the United States, but then identifies the focus of the verse on a very specific group.
And where is that band who so vauntingly swore
That the havock of war and the battle's confusion A home and a country should leave us no more?
Their blood has wash'd out their foul foot-steps' pollution,
------>No refuge could save the hireling and slave,
From the terror of flight or the gloom of the grave;
Who were the "hireling and slave" who were, the anthem tells us, cast out or killed?
In 1814, Great Britain had been at war with the United States for two years. The British Empire urgently sought ways to hit the United States away from the Canadian border, where American invasion forces advanced, with many in the United States government (and outside it, such as still-influential former President Thomas Jefferson (1743-1826)) seeing the war as a chance to "finish the revolution" and liberate the rest of British North America.
The Royal Navy officer Sir Alexander Cochrane (1758-1832) looked to the precedent set by "Dunmore's Proclaimation" (1775) of the American revolution, in which the slaves of rebels had been offered freedom for service to the Crown - the survivors of the 20,000 American slaves who fought for "King and Freedom" in the American revolution were now the "black Loyalists" community of Canada. Already in the War of 1812 many American slaves were fleeing into British hands, such as "Presley", a slave owned by Dr Walter Jones of Kinsale, Virginia, a friend of Thomas Jefferson, who fled in November 1813 to HMS Havannah.

Sir Alexander landed agents along the US East coast, who distributed calls for slaves to join the British. British forces then used their naval superiority to occupy Tangier Island (in Chesapeake Bay, part of Accomack County, Virginia) and this was to became the home of a new generation of freedom-seeking black Americans, which rapidly grew as American slaves fled to the British fort "Fort Albion" built on the island; the fit men were organised into a new British Army unit - The Corps of Colonial Marines.
Sir Alexander instructed his forces that raids in the area of Chesapeake Bay were very particularly aimed at liberating slaves, and thus increasing British striking power: “Let the landings you make be more for the protection of the desertion of the Black Population than with a view to any other advantage ... The great point to be attained is the cordial support of the Black Population. With them properly armed & backed with 20,000 British troops, [President] Madison will be hurled from his throne.” This was based on the correct assumption that many American slaves felt no loyalty towards the country that held them as chattel.
With the ever-present fear of slave uprisings fostered by their own vulnerability to their slaves, and the bloody result of the Haitian revolution (1791-1804) high in the American popular mind, this call for slave revolt was as an extremely hostile act against the United States; indeed some abolitionist British officers imagined and advocated that with sufficient aid from Britain, revolutionary free black republics (akin to Haiti) could arise in the Carolinas or Georgia, completely destabilising the USA. This included Commodore Sir John Beresford (1766-1844) who wrote that an invasion of the southern states of the USA "might be rendered infinitely more formidable by the emancipation of the Slaves & purposes of humanity might be answered by it, for they are cruelly oppressed."
The Colonial Marines were spared the standard British military punishment of flogging, which was recognised by their on-site commander, Rear Admiral Sir George Cockburn (1772-1853) as too close to the punishments that prevailed for slaves. Instead, Colonial Marines were 'punished' by being forced to wear their Redcoats inside out for a period, with the white lining fully exposed.
Creating a new 'black Republic' on the ruins of the United States was not taken as an official aim of British strategy, likely out of fear that more free black countries beyond Haiti would lead to rebellions in slave-owning British West Indian colonies, which were significant financial interests for many in the British establishment.
