1782: Rodney defeats French in Battle of the Saints - British naval superiority in the Caribbean established; Gibraltar repels Franco Spanish attack;
France financially exhausted; some British reinforcements present in America.
1782/3: British concede American independence and agree generous boundary south and west of the Great Lakes and favourable terms for American shipping entering British ports.

Clearly Britain was defeated with reference to the greater point of American independence; but what about the linits of the new American state?

1. How could the Treaty of Paris be renegotiated more or less advantageously for Britain or the USA - i.e. what other plausible boundaries for the USA and Canada are there.
2. As an aside do you agree that Shelburne's 'generous' terms with the USA in 1783 marked an informal doctrine in British foreign policy not to come to loggerheads with the USA unless in defence of vital national interests. For example President Madison and Secretary of State Adams later admitted that they would not have gone to war in 1812 had the British concessions been received before their declaration; British concessions regarding Maine and Oregon, etc. Just a thought.
