The Case was a secret trial, unlike the Moscow Show Trials. It is traditionally considered one of the key trials of the Great Purge. Marshal Mikhail Tukhachevsky and the senior military officers Iona Yakir, Ieronim Uborevich, Robert Eideman, August Kork, Vitovt Putna, Boris Feldman, and Vitaly Primakov (as well as Yakov Gamarnik, who committed suicide before the investigations began) were accused of anti-Soviet conspiracy and sentenced to death; they were executed on the night of June 11 to 12, 1937, immediately after the verdict delivered by a Special Session (специальное судебное присутствие) of the Supreme Court of the USSR.
