BBC - The Silent War (2013) Part 1 Know Your Enemy

The story of the underwater war between US, UK and Soviet submarines in the second half of the 20th century.

Part 1: Know Your Enemy

For decades, Britain and America's Cold War submarines waged a secret war of espionage against the Soviet navy. Deep in the ocean, crews were locked in a game of cat and mouse as each side battled to gain the tactical and technological advantage. After decades of silence, submariners from both the east and west are now allowed to talk more openly than ever before about how they plotted to win the war beneath the waves. The west's superior technology allowed them to secretly shadow the Soviet fleet, at close quarters, giving them vital intelligence and the upper hand if war broke out. Shadowing submarines was dangerous. The film explores close encounters between western and Soviet forces that put the lives of submariners at risk. Candid interviews with British, American and Russian submariners reveal the pressures of lengthy underwater patrols that drove them to the edge of their physical and mental limits.
