The British government, already at war with Napoleonic France, adopted a defensive strategy against the United States when the Americans declared war in 1812. Reinforcements were held back from Canada and reliance was instead made on local militias and native allies to bolster the British Army in Canada. However, after the defeat and exile of Napoleon Bonaparte in April 1814, Britain was able to use its now available troops and ships to prosecute its war with the United States. The Earl of Bathurst, Secretary of State for War and the Colonies, dispatched an army brigade and additional naval vessels to Bermuda, from where a blockade of the US coast and even the occupation of some coastal islands had been overseen throughout the war. It was decided to use these forces in raids along the Atlantic seaboard to draw American forces away from Canada.
