The British military generally believed that if war did occur, they could transport troops to Canada if asked, but nonetheless saw it as impossible to defend Canada against the much larger United States, so did not plan to render aid, as Canada's loss would not be fatal to Britain. A full invasion of the United States was unrealistic and a naval blockade would be too slow. The Royal Navy could not use a defensive strategy of waiting for the American fleet to cross the Atlantic because Imperial trade would be left too vulnerable. Royal Navy officers believed that Britain was vulnerable to a supply blockade and that if a larger American fleet appeared near the British Isles, the Isles may quickly surrender. The officers planned to, instead, attack the American fleet from a Western Hemisphere base, likely Bermuda, while other ships based in Canada and the West Indies would attack American shipping and protect Imperial trade. The British would also bombard coastal bases and make small amphibious assaults. India and Australia would help capture Manila to prevent American attacks on British trade in Asia and perhaps a conquest of Hong Kong. The officers hoped that such acts would result in a stalemate making continued war unpopular in the United States, followed by a negotiated peace.
