From the horse's mouth: Luftwaffe POWs as sources for air ministry intelligence during the battle of Britain

British military intelligence as derived from the interrogation of prisoners‐of‐war (POWs) during the Second World War has been under‐valued by historians, whose attention has focused primarily on signals intelligence. While Sigint, in particular Ultra, was of undoubted value, Britain's armed services nevertheless attached much credence to POW‐derived intelligence, and by the war's end an abundance of information had been gleaned from the half a million plus Axis prisoners by then held in Britain. This article will examine the work of the Air Ministry Intelligence section known as AI1(K), which was responsible for POW interrogation, during the Battle of Britain, and attempt to illustrate both the wealth and value of such intelligence at a time when Ultra was still in its infancy.
