Germany lost WW2, they did not beat Britain and whilst they 'occupied' France they withdrew after being defeated by allied forces.
Britain and France had a defence pact with Poland. When German forces attacked Poland on 1st September 1939, Britain and France demanded that they withdraw. Germany ignored the request, so on 3rd September 1939 Britain and France issued a joint declaration of war against Germany.
France were happy to support anyone in a war against Britain, and funded the revolutionary forces. France and the US have a close relationship even today, represented by the statue of Liberty, which was a gift from France to the US in celebration of 100 since the revolution.
The allied forces(USA, France, Britain, Belguim,Italy etc)
The French Forces in Britain was very small. Not that many made it out of France after the Battle of Dunquerqe (Dunkirk). The French armed forces did join with Britain and the US forces and they were known as the allied forces.
On September 1st 1939, German Forces overran Poland on land and air. Britain and France had a defence agreement with Poland and immediately demanded that German forces withdraw from Poland. Germany ignored the ultimatum, so on September 3rd 1939, Britain and France jointly declared war on Germany.
Jay's Treaty of 1794 angered France because the U.S. refused to lend aid to France and the treaty joined forces with Britain.
The Allied Forces of World War 2 consisted primarily of Britain, Russia, and the US. France was an ally as well until it fell in early 1940.
