What happens as a result? Pitt the Younger and friends wanted to cut Russia down in size at the time and Russian bribery in London sabotaged approval for war. Apparently Prussia's King at the time wanted to expand in the Baltic at Russia's expense.
What if these two countries, members of the "Triple Alliance" of 1788 with the Netherlands, had gotten the war they sought?
Could Prussia and Britain win against Russia? If they won, what would they get?
Or would Russia defeat the Prussians and British on land?
