After the failed White Advance on Moscow in Summer 1919, the Red Army had started a counteroffensive in Autumn 1919, which after several hard-fought battles, had by Winter 1919-1920 turned into a rout of the White forces. On January 17, 1920 the troops of the Red Army seized Krivoi Rog and Apostolove. On January 24, they captured Yelisavetgrad and on January 25, Uman. By the end of January, Kherson, Mykolaiv and Voznesensk were captured. On February 3, Olviopol and Ochakov were captured. On February 6, the Red Army approached Odessa. Early in the morning ofFebruary 7, they broke into the city, and on February 8, Odessa was completely captured by the Red Army. Great help to the Red Army in taking the city was provided by the Odessa workers, who, on the orders of the Revolutionary Committee, had taken up arms and seized critical points in Odessa just before the approach of the regular units.
Aware of the desperate situation, the command of the AFSR in Odessa had started an evacuation over the Black Sea on February 3. Contemporaries of events and historians called the Odessa evacuation of 1920, ill prepared and "mediocre". Only 1 in 3 could be evacuated. In the city of Odessa, 3 AFSR generals, about 200 officers and 3,000 soldiers were taken prisoner. According to reports of the Odessa Soviet newspapers of those days, 300,000 pounds of grain also remained in the port of Odessa, 50,000 pounds were found on barges moored in the quarantine harbor. On the ship "Alexandria" a load of brand new British motorcycles of the brand "Triumph" was found, sent by England to the AFSR and 3,000 pounds of coal. The Railroad tracks were clogged with abandoned wagons with a variety of goods evacuated from Kiev and current Southern Ukraine, including 130,000 pounds of firewood. The total number of evacuees is difficult to calculate, as transport ships with evacuees dispersed to different ports and many refugees were evacuated privately. Soviet sources reported 3,000 evacuees, which did not correspond to reality. White Guard sources reported 16,000 as a reasonable minimum number of evacuees, with about 40,000 people willing to be evacuated. From the military equipment and supplies, it was possible to evacuate all the tanks that had arrived in Odessa from Nikolaev, almost all serviceable armored vehicles and parts of the equipment of the technical troops, cars and aviation assets. The British ships involved in the evacuation were :
HMT Rio Negro, received about 1,400 refugees, wounded officers and cadets. Went to the port of Thessaloniki
The garrison of Odessa and other parts of the AFSR, which had previously retreated to the city, as well as various detachments of "militiamen" could not be evacuated by sea. They united in the "Ovidiopol detachment" and were ordered to march to the border with Romania. They were accompanied by a large number of civilians, families of officers of the Volunteer Army, foreigners, wounded and about 600 cadets of the Odessa Cadet Corps. About 16,000 people, of which no more than 3,000 were able to carry weapons, departed in mid-winter from Odessa on February 7 and moved to the Gross-Liebental - Ovidiopol area, from where they intended to go to Romania. But they were not admitted into Romania by the Romanian authorities and found themselves trapped as the Red units took Maiac and Tiraspol, thus depriving the "Ovidiopol detachment" of the possibility of uniting with the "Bredov detachment", and marching towards Poland. The Ovidiopol detachment was not allowed by the Romanians into their territory. The Romanians did not even let the Cadet children enter, but fired their artillery when a Cadet column headed towards them over the ice across the Dniester. The trapped Ovidiopol detachment lost hundreds of people from attacks by the Red cavalry, shelling by Romanian troops and local marauders. After 5-7 days, the remaining 12,000 people capitulated. At that time, many officers committed suicide, preferring death to Bolshevik captivity.
The Bredov detachment
The units of the AFSR under command of Lieutenant-General Nikolai Bredov and all troops in right-bank Ukraine, were ordered by Lieutenant-General Schilling to march towards Poland. Accompanied by numerous refugees and civilians, they carried out an unprecedented winter march, under constant pressure of superior Red forces, and reached Poland. This march became known as the Bredov Campaign.
Results
By the end of February 1920, all White forces had been chased from Western-Ukraine. The AFSR now only held the Northern Caucasus and Crimea. In total, about 1,200 officers were captured by the Reds. All of them were placed in concentration camps, where they were gradually shot. A mass shooting was held on May 5, 1920. In Odessa, 100 guns of different calibers, four armored vehicles, four armored trains, several hundred thousand shells and cartridges, some engineering, automobile, aviation and other property, and tons of food were captured by the Red Army.
