So, in OTL, from 1798-1800 the Quasi-War took place, which was an undeclared war between the USA and France. It was mostly a naval war, and was a result of French attacks on American shipping. So let's say, there was a full out war between the two republics. If other nations such as Great Britain and Spain did not participate in this war, and nations like Prussia and Austria stopped fighting Napoleon, (I know this is highly unrealistic and probably ASB) what would have happened and who would have one for each of these scenarios?
Scenario A: It is mostly a naval war, with pretty much the entirety of the war consisting of several large naval actions and lots of smaller ones.
Scenario B: France decides to launch an invasion of the United States. How long could France last before the invasion force is destroyed? How much land could they occupy/conquer?
Scenario C: The USA decides to launch an invasion of France. How long could the USA last before the invasion force is destroyed? How much land could they occupy/conquer?
