WW1 Paved the Way for the Battle of Britain.

One should keep in mind that BoB was the FIRST ever attempt for an oversea invasion with air power playing a role, afaik. There was NO precedent to learn from and learning was by doing it. And it was obviously a very difficult task. And it was done against a defense system that was by its time unique and extremely efficient.

WW1 was a complete different story and the raids had a completely different task.
