Black Sailors and Soldiers in the War of 1812 

At the end of the war Americans demanded the either the return of ex-slaves or monetary reparations for the loss of property.  With few exceptions, the British refused.  According to custom, a slave arriving on British soil was free; a British ship at war had the status of British land itself.

The British offered the Colonial Marines farmland in Trinidad in February 1816, nearly a year after the end of the war, when the marines refused to be transferred out of naval service into the army as soldiers in the West India Regiments.  Their descendants live in Trinidad still, in freedom, and call themselves "the Merikans."
