The Silent Listener: British Eavesdropping in the Falklands War

D. J. Thorp, a signals intelligence officer in the British Army, spent many years eavesdropping on the hot spots of the Cold War in Europe and the Middle East. In 1982 he found himself on board a Royal Navy ship intercepting signals from the Argentinean military as it fought the British in the Falklands War. Listen in as Major Thorp describes to SPY Historian Mark Stout how signals intelligence influenced the course of that war, how his team uncovered an Argentinean plan for a counterattack that could have turned the tide of the war, and even how a signals intercept led British naval personnel to shave off their beards!
