Having placed President Mikhail Gorbachev of the Union of Soviet Socialist Republics under house arrest, the eight high-level Soviet officials known as the Gang of Eight declared a state of emergency across the Soviet Union and announced that they had formed the State Committee on the State of Emergency (GKChP) to manage the country and restore Soviet dignity. The GKChP sent the Soviet Army into Moscow, Leningrad, the Baltic states, and Moldova but failed to capture Russian President Boris Yeltsin, who held out in the White House, Moscow.
