Several of the foreign fighters were from countries that had been over run by the Germans, so any of the military that escaped capture went to Britain to continue the war and reclaim their country.

No. France had already surrendered before the start of the Battle of Britain. Britain was fighting alone apart from some volunteers from several countries.
The Battle of Britain was an air battle.
After the Battle of Saratoga, in which the Patriots won and beat the British, many countries made official alliances with Britain. Before that battle, European countries were secretly supporting the Thirteen Colonies. After it, enemies of Britain such as France, Spain, and the Netherlands made alliances with the Thirteen Colonies and against the British. The Battle of Saratoga was a battle that was known as 'the turning point of the war', because at this point, after that battle, Britain was fighting a five-theatre war.
