How did the Soviet Union respond to the naval blockade?

In response to the naval blockade during the Cuban Missile Crisis in 1962, the Soviet Union initially escalated tensions by sending ships towards Cuba, signaling their intent to challenge the blockade. However, after intense negotiations and the threat of military confrontation, Soviet Premier Nikita Khrushchev ultimately decided to withdraw the missiles from Cuba in exchange for a secret agreement to remove U.S. missiles from Turkey and a commitment not to invade Cuba. This resolution helped avert a potential nuclear conflict while highlighting the limits of direct military engagement between the superpowers.
