Alexander Kolchak

Kolchak was proclaimed Supreme Ruler of Russia by the White forces in Omsk. He established a government that claimed authority over all anti-Bolshevik forces. His regime was recognized by the Allies and became the main White government in Siberia.

Kolchak's government gained control of a large portion of the Russian Empire's gold reserve, which had been captured by the Czechoslovak Legion. The gold was used to finance his government and purchase supplies. Its fate after Kolchak's defeat remains a subject of speculation.

Kolchak launched a major offensive westward from Siberia, aiming to link up with Denikin's forces and march on Moscow. The offensive initially captured large areas, including Perm and Ufa, but was halted by the Red Army and turned into a retreat.

After the collapse of his government, Kolchak was captured by the Czechoslovak Legion and handed over to the Bolsheviks in Irkutsk. He was executed by firing squad on February 7, 1920, and his body was thrown into the Angara River.
