James Holland presents a fresh analysis into the Battle of Britain, exploring the lesser-told German point of view, and highlighting the role of those who supported 'The Few' during the summer of 1940. Focusing on the tactics, technologies and intelligence available to both sides, Holland examines the ways in which both Germany and Britain used their resources: from aircraft to air defence, and from intelligence to organisation. And, by gaining rare first-hand testimony from German veterans, and access to the untapped diaries and documents, we reveal that this was a battle of two sides and many layers.
