From Moscow, December 25, 1991: The Last Day of the Soviet Union, by Conor O’Clery (PublicAffairs, 2011), Kindle pp. 140-141:
Two hundred and fifty thousand pairs of handcuffs had been ordered from a factory in Pskov, and Lefortovo prison made ready for an influx of detainees.
The coup got under way the next day, Sunday, August 18, with the house arrest of Mikhail Gorbachev. A military plane provided by Yazov landed at the Belbek military base near Foros at 5 p.m. after a two-hour flight from Moscow. On board were Baklanov, Shenin, Boldin, and another enthusiastic putschist, General Valentin Varennikov. The four men represented the pillars of the Soviet establishment. Baklanov, with broad earnest face and furrowed brow, was head of the Soviet Union’s military-industrial complex. Shenin, prematurely bald with large domed forehead, was the Politburo member responsible for party organization. Boldin, besides being Gorbachev’s chief of staff, was a senior member of the Central Committee. Varennikov, in large rimless glasses with a thin moustache and lank hair combed over in Hitler style, was commander of Soviet land forces.
The delegation was driven by KGB officers in two Zil limousines to the state dacha with marble walls and orange-tiled roof, where the Gorbachevs were spending the last day of their two-week summer vacation. They were joined inside the compound gate by another plotter, General Yury Plekhanov, the stolid unsmiling head of the KGB’s Ninth Directorate, who represented a fifth pillar of Soviet power, the security organs. Plekhanov deployed new guards around the perimeter of the dacha, ordered the head of Gorbachev’s security to return to Moscow and put men with automatic weapons outside the garage so none of Gorbachev’s party could get to the cars or use the radio telephones in the automobiles.
The president was in his second-floor office dressed in shorts and a pullover, reading the text of the speech he would give to launch the new Union in Moscow in two days’ time. In it he had written a warning: “If we turn back now, our children will never forgive us such ignorance and irresponsibility.”
In a guesthouse on the dacha compound, Colonel Vladimir Kirillov, one of the two plainclothes officers in charge of the nuclear suitcase, was watching television when the screen went blank. An emergency light on the chemodanchik started blinking. This was it—a nuclear alert! He picked up his radio telephone with a direct link to government communications. He was told there had been an accident and not to worry. At 4:32 p.m. he lost contact with his controller in Moscow, KGB general Viktor Boldyrev. General Varennikov appeared at the door. “How are your communications?” he asked. “There aren’t any,” replied the colonel. “That’s how it should be,” said Varennikov. He assured him that contacts would be restored within twenty-four hours.
At 4:50 p.m. the head of Gorbachev’s bodyguard interrupted the president to say that a group of people had arrived to speak with him. Gorbachev was not expecting anyone. Somewhat alarmed, he picked up a receiver to call Kryuchkov in Moscow. The line was dead. All four telephones on his desk and the internal phone were no longer working. In an outer office Anatoly Chernyaev suddenly realized that his government line, satellite link, and internal telephone were all down.
He guessed immediately what was up.
