The Trial of the 20 was held in front of a special sitting of the Senate, in St Petersburg, on 9–15 February 1882.[3] The defendants were: Aleksander Mikhailov, Nikolai Morozov, Aizik Aronchik, Alexander Barannikov, Mikhail Frolenko, Grigori Isaev, Nikolai Kletochnikov, Nikolai Kolodkevich, Martyn Langans, Tatyana Lebedeva, Nikolai Sukhanov, Makar Teterka, Anna Yakimova, Ivan Emelyanov, Grigori Fridenson, Lyudmila Terentyeva, Mikhail Trigoni, Lev Zlatopolsky, Ferdinand Lustig, and Vasili Merkulov.
At the conclusion of the trial, ten of the defendants were sentenced to death. They included two women - Lebedeva, and Yakimova, who was pregnant. Three others were sentenced to hard labour for life; three - Terentyeva, Trigoni and Zlapolsky - were sentenced to 20 years hard labour; Fridenson to ten years and Lustig to four years hard labour.
Merkulov, a carpenter arrested in February 1881 for his part in trying to mine the Tsar's train near Odessa, who co-operated with the police, and gave evidence against the others.[4] was pardoned.
The death sentences invoked a reaction in Russia, and abroad. The French novelist Victor Hugo, who was particularly distressed by the prospect that two women were to be hanged, as had already happened to Perovskaya, wrote an impassioned letter to the new Tsar, Alexander III, pleading: "In the darkness, I cry for mercy."[5]
Leo Tolstoy also wrote to Alexander III in March 1881, pleading for clemency, and warning: "If you do not forgive, but execute the criminals, you will have uprooted three or four individuals from among hundreds and, evil begetting evil, 30 or 40 more will grow up in place of these three or four."[6] He sent the letter to the Chief Procurator of the Holy Synod, Konstantin Pobedonostsev asking him to pass it on to the Tsar, but Pobedonostsev, who wanted to see the revolutionaries executed, held on to it until after Perovskaya and four others had been hanged.[7]
All the death sentences were commuted to life imprisonment, except in the case of Sukhanov, a lieutenant in the imperial navy, who was shot in front of the fleet in Konstadt on 19 March 1881.[8]
