On August 18th, 1991, the hardliners detained Gorbachev at his
vacation home on the Black Sea. They did not want him as the
president of the Soviet Union, and demanded his resignation. On
August 2oth, the hardliners ordered troops to attack the parliament
building, which they refused, which turned the tides, and Gorbachev
returned to Moscow.
The ultimate outcome was the accelerated breakup of the Soviet
Union and rise of Boris Yeltsin to popularity and power.
