On the 40th anniversary of the Falklands War, this landmark documentary reveals the untold story of the conflict that saw Britain send nearly 30,000 young soldiers, sailors and aircrew 8000 miles to the South Atlantic – to reclaim the Falklands Islands after invasion by Argentina. It was the biggest amphibious operation Britain had undertaken since D-Day. In a war that transformed the fortunes of Margaret Thatcher and her government, a hard-won victory was almost undermined by a series of flaws in the British operation. The head of the SAS in the Falklands, Sir Michael Rose, speaks publicly for the first time about how the British task force came close to defeat. Ground troops speak candidly about their experiences and senior commanders, many for the first time, reveal how unexpected changes in the plans for the land campaign could have cost Britain the war and led to unnecessary loss of life at the iconic Battle of Goose Green and in the attacks on the Sir Galahad and the Sir Tristram at Fitzroy. Uncovering recordings of the negotiations to end the conflict, and British clandestine missions in Chile, 40 years later the Falklands War surrenders its secrets. Part of Channel 4’s Secret History strand.
