Soviet leader Nikita Khrushchev and Fidel Castro agreed on the secret placement of nuclear missiles secretly in Cuba. The Soviet Union’s code name for the nuclear missiles placement was Operation Anadyr .
The Soviets sneaked in thousands of troops wearing checkered shirts and tight quarters and posed as civilian agricultural advisers into Cuba. Many more troops were hidden and sent aboard a fleet of 85 ships loaded with Arctic equipment to Cuba. During this period, the two superpowers – the U.S. and the Soviet Union – were involved in a silent battle for supremacy, known as the Cold War. This followed a series of geopolitical clashes.
