The Battle of Cape Matapan was portrayed by the British, even after the war, as a clever move by Admiral Cunningham, who in his memoirs would portray himself as a new Nelson. In reality, the British knew exactly what the Royal Navy’s orders were and where he was, thanks to Ultra intercepts. After the war, the Italian Navy would be searched for the culprit behind the leak. Only decades later would the truth emerge from the monumental history of British intelligence by Professor Francis Harry Hinsley (former Bletchley Park prodigy).
