Can anyone identify a Wg Cdr Smallwood who was Wing Commander Flying at Bolt Head in May 1944? Was it 40645 Denis G. Smallwood DFC, later Air Chief Marshal Sir Denis Smallwood GBE KCB DSO DFC?

Malcolm's RAFweb site offers cirsumstancial but not definitive evidence (http://www.rafweb.org/Biographies/Smallwood.htm). Can anyone definitively identify 'my' man, please?

Thanks
Steve
