The confrontation between the old and the new authorities intensified after the uprising of the Czechoslovak corps, which broke out on May 25, 1918. Well-organized and armed troops of the corps overthrew the Soviet government along the Trans-Siberian Railway. Tomsk surrendered without a fight. Barnaul fell on June 15. After the capture of Omsk, the Czechoslovaks moved to Ishim and Tobolsk.
On the night of June 19, 1918, the Czechs and Whites, led by Captain Nikolai Nikolaevich Kazagrandi, landed on the shore of the Irtysh and took Tobolsk. On June 20, the Whites took Tyumen.
On June 30, 1918, the Provisional Siberian Government headed by Pyotr Vasilyevich Vologda was established in Omsk. Omsk became the white capital of Russia, as opposed to Moscow.
On the night of July 17, 1918, the royal family was shot in Yekaterinburg. Servants and confidants were executed along with them. In total, 11 people were shot in the basement of engineer Ipatiev’s house.
The situation of the Provisional Siberian Government in the autumn of 1918 was greatly complicated due to failures at the front. Under these conditions, the Socialist revolutionaries of the Urals and Siberia created a coalition government — Directory under the chairmanship of N.D. Avksentiev. Anarchy and chaos were growing in the region.
On the night of November 18, 1918, Admiral A.V. Kolchak arrested the members of the Directory and declared himself the Supreme Ruler of Russia. Kolchak banned trade unions and parties, and limited the powers of local governments. The townspeople were dissatisfied with the rise in prices, the shortage of food, and in Kolchak’s army began a decline in discipline and mass desertion, especially among peasants who were mobilized by force.
In the summer of 1919, a clear turn in favor of the Red Army was marked at the front. Already on September 3, 1919, the Whites stopped defending Tobolsk and retreated to Uvat and Demyanka. However, Kolchak ordered Tobolsk to be recaptured. White reserves were thrown into battle, on September 27, 1919, the Whites took Tobolsk.
On October 11, 1919, the Supreme Ruler A.V. Kolchak himself visited Tobolsk. He held a meeting on the issue of the export of church valuables from Tobolsk and the branch of the state bank. A week later, the retreat of the Whites from Tobolsk to the north and east began. The Whites failed to gain a foothold in Ishim. On October 22, 1919, the Reds took Tobolsk, on October 31 — Petropavlovsk, on November 4 — Ishim.
In the Tobolsk North, a partisan movement turned against the whites. The partisan detachments were mainly peasants who had deserted from the Siberian Army. On November 17−18, the village of Samarovo was taken. By this time, many partisan detachments numbered up to 250 people.
On November 13, 1919, five trains of A.V. Kolchak with his headquarters and gold reserves (28 wagons with gold) left Omsk for Novonikolaevsk. On November 14, 1919, the 27th Infantry Division of the Reds reached the outskirts of Omsk.
After the surrender of Omsk, the remnants of the whites slowly retreated towards Novonikolaevsk. Kolchak himself fled to Irkutsk, but ended up with the White Russians, who turned him over to the Reds.
December 14, 1919 The Red Army took Novonikolaevsk. On December 20, 1919, the Reds took Tomsk.
On February 7, 1920, at 5 a.m., Kolchak and the Minister of the Provisional Government, Viktor Nikolaevich Pepelyaev, were shot on the ice of a Hangar near the mouth of the Ushakovka River. The execution was led by the chairman of gubchek, Samuel Chudnovsky, and the firing squad was led by Ivan Bursak (real name — Boris Yakovlevich Blatlinder).
The battles of the Red Army units with separate detachments of whites continued in the North of the Tobolsk province until March 1920. During these battles, the Whites were finally defeated.
