rupertbri,
I'm not sure whether ColinB still follows this forum and so as I also have the book, I'll answer. Unfortunately there appears to be no mention of Frederick Pierson Hill.
"Heroes of the Birmingham Air Raids" describes specific incidents where the contribution of individuals of many services, and also civilians, was recognised with a bravery award. AFS men are listed, as well as those in the ARP, Home Guard, R.E Bomb Disposal units, Police, the railway companies, factories and so on. There is also an AFS Roll of Honour listing those AFS men who lost their lives.
I imagine that the book mentions only a tiny fraction of all the men and women who were involved in one way or another with the Birmingham Blitz. Many of the countless others would also have performed acts of bravery in the line of duty but have gone unrecognised and are therefore forgotten outside the circle of family and friends. This forum is a way of remembering them and what they did.
