All very well , but how many ex- French Airforce or French Contract Curtis Mohawks and Tomahawks were in UK during BofB? They had been diverted to UK. Were they available for use IF required?

By the time the Battle of Britain began only one squadron of the Gladiator biplane fighter remained in the UK, this being No. 247 Squadron based at RAF Roborough (10 Group), north of Plymouth, Devon. The Squadron was not re-equipped with Hurricanes until Christmas Eve, 1940.
