brummie nick. Thanks for searching the web about the Squadrons. I had come across that page. It gives the balloon states for August 1940, by which time 912 Sqn had been sent to France & evacuated in the May. On return to England they did not return to Birmingham, which is why they did not feature in the list. I believe 962 was formed after the start of the war from elements of the Birmingham Squadrons, which is why it is probably shown as coming under No 5 BC. The place Rowkeath for 915 Sqn really confused me, I couldn't find it anywhere. In fact it was the Bourneville Lido at ROWHEATH! No 31 (Barrage Balloon) Group controlled all the Balloon Centres in Liverpool and Derby as well as Birmingham. It was based at Forhill House near Hopwood, not far from RAF Wythall. In November 1941 following reorganisation in Balloon Command, 31 (BB) Group disbanded and the Birmingham Squadrons came under 32 (BB) Group. Forhill House was a pretty impressive mansion, so I was not surprised to find out that 914 Sqn took it over as their Squadron HQ. Still standing, it has just been converted into private flats, so I could not get a photo of it.
The list of the Squadrons you found was compiled by Len Bacon from Hull. He has researched No 17 Balloon Centre in Hull, and the 2 Balloon Squadrons based there. My project is a bit grander, with 2 Balloon Centres, & 7 Squadrons. As I no longer live in Birmingham, I would just like to say how much I appreciate all the help you are providing.
