Don Army
By 1914, the population had reached 54,000. The main source of income was coal mining, which had been carried out in that region since the end of the 18th century. The population was poor, but the town had rail, telegraph and telephone networks, electricity and plumbing as well as libraries, hospitals and a post office. 1917 saw the city change hands three times, until it was taken on April 28, 1919, by the Don Army, under General Fitskhelaurov. For twenty months it was independent of the Bolsheviks, but was ravaged by typhoid.
