Okay, during the War of Independence, the great powers conveniently set up a number of proposed territorial resolutions designed to make fodder for alternate historians 200 hundred and thirty years later. amogn them:
1) France sent troops to protect South Africa from the British, or at least to stop off enroute to India, under Suffren. The French debated keeping it; Britain would have been compensated with more territory in India.
(Presumably this didn't happen because the Dutch were allies).
2) Britain offered Russia Minorca if it would join the war as a Briitsh ally, or adopt a pro-British stance.
3) Britain debated offering to swap Gibraltar for a Spanish Caribbean island.
There were a few more, but any thoughts on these? The main thing that occurs ot me is that they suggest Britain was farm ore desperate than I imagined; by Amiens the British were sufficiently worried about Russia as to oppose their presence in the Mediterranean.
