Question: By how many votes did the person the organizers wanted to arrest survive impeachment?

Knowledge 1: Dissolution of the Soviet Union
Thousands of Muscovites came out to defend the White House (the Russian Federation's parliament and Yeltsin's office), the symbolic seat of Russian sovereignty at the time. The organizers tried but ultimately failed to arrest Yeltsin, who rallied opposition to the coup with speech-making atop a tank. The special forces dispatched by the coup leaders took up positions near the White House, but members refused to storm the barricaded building. The coup leaders also neglected to jam foreign news broadcasts, so many Muscovites watched it unfold live on CNN. Even the isolated Gorbachev was able to stay abreast of developments by tuning into BBC World Service on a small transistor radio. [SEP] Knowledge 2: 1993 Russian constitutional crisis
The ninth congress, which opened on March 26, began with an extraordinary session of the Congress of People's Deputies taking up discussions of emergency measures to defend the constitution, including impeachment of President Yeltsin. Yeltsin conceded that he had made mistakes and reached out to swing voters in parliament. Yeltsin narrowly survived an impeachment vote on March 28, votes for impeachment falling 72 short of the 689 votes needed for a 2/3 majority. The similar proposal to dismiss Ruslan Khasbulatov, the chairman of the Supreme Soviet was defeated by a wider margin (339 in favour of the motion), though 614 deputies had initially been in favour of including the re-election of the chairman in the agenda, a tell-tale sign of the weakness of Khasbulatov's own positions (517 votes for would have sufficed to dismiss the speaker).By the time of the ninth Congress, the legislative branch was dominated by the joint communist-nationalist Russian Unity bloc, which included representatives of the CPRF and the Fatherland faction (communists, retired military personnel, and other deputies of a socialist orientation), Agrarian Union, and the faction "Russia" led by Sergey Baburin. Together with more 'centrist' groups (e.g. 'Change' (Смена)), the Yeltsin supporters ('Democratic Russia', 'Radical democrats') were clearly left in the minority.
Knowledge 1: Umayyad Caliphate
After the assassination of Uthman in 656, Ali, a member of the Quraysh tribe and the cousin and son-in-law of Muhammad, was elected as the caliph. He soon met with resistance from several factions, owing to his relative political inexperience. Ali moved his capital from Medina to Kufa. The resulting conflict, which lasted from 656 until 661, is known as the First Fitna ("civil war"). Muawiyah I, the governor of Syria, a relative of Uthman ibn al-Affan and Marwan I, wanted the culprits arrested. Marwan I manipulated everyone and created conflict. Aisha, the wife of Muhammad, and Talhah and Al-Zubayr, two of the companions of Muhammad, went to Basra to tell Ali to arrest the culprits who murdered Uthman. Marwan I and other people who wanted conflict manipulated everyone to fight. The two sides clashed at the Battle of the Camel in 656, where Ali won a decisive victory.
