A Soviet freighter is stopped at the quarantine line and is searched for military supplies. None are found, so the ship is allowed to pass. More importantly, Fidel Castro sends a private letter to Nikita Khrushchev urging him to launch a nuclear first strike on America in case of an American invasion of Cuba. As the first breaking point of the tension, Khrushchev sends a long, bloated letter to Kennedy saying that the missiles will be removed in an exchange for the removal of the quarantine and a pledge from the U.S. not to invade Cuba. Also, in a plan that was carried out in secret for 25 years, a removal of the American missiles in Turkey.
Day 12 - October 27
Another letter of terms is received from Moscow, this times with tougher demands. It calls for removal of Jupiter missiles from Turkey. Over Cuba, a U-2 spy plane is shot down by a Soviet missile. The pilot, Major Rudolph Anderson is killed and receives a Distinguished Service Metal posthumously.
Day 13 - October 28
Finally, the 13 days that mark the most tense and dangerous period of the Cuban Missile Crisis are over.
