Alexander Sedyakin was executed during a campaign that occurred during what years?
Great Purge The Great Purge or the Great Terror (Russian: Большо́й терро́р ) was a campaign of political repression in the Soviet Union which occurred from 1936 to 1938. It involved a large-scale purge of the Communist Party and government officials, repression of peasants and the Red Army leadership, widespread police surveillance, suspicion of "saboteurs", "counter-revolutionaries", imprisonment, and arbitrary executions. Mobile gas vans were invented to execute people without trial. In Russian historiography, the period of the most intense purge, 1937–1938, is called Yezhovshchina (Russian: Ежовщина ; literally, "Yezhov phenomenon", commonly translated as "times of Yezhov" or "doings of Yezhov"), after Nikolai Yezhov, the head of the Soviet secret police, the NKVD, who was later killed in the purge. It has been estimated that 600,000 people died at the hands of the Soviet government during the Purge.
Battle of the Great Redan The Battle of the Great Redan was a major battle during the Crimean War, fought between British forces against Russia on 18 June and 8 September 1855 as a part of the Siege of Sevastopol. The French army successfully stormed the Malakoff redoubt, whereas a simultaneous British attack on the Great Redan to the south of the Malakoff was repulsed. Contemporary commentators have suggested that, although the Redan became so important to the Victorians, it was probably not vital to the taking of Sevastopol. The fort at Malakhov was much more important and it was in the French sphere of influence. It was when the French stormed it after an eleven-month siege that the final, somewhat unnecessary attack on the Redan was made.
