Last night I watched a programme about the Battle of Britain. Dennis David, a fighter pilot with 87 squadron said something like this:

It just made us so bloody angry, these planes with black crosses on flying over our country. They were bombing our mothers. It made us aggressive, and it made us absolutely determined to give a good account of ourselves.

They certainly did, against a deadly and vastly more numerous foe. They fought for their county and their mothers. They won.
