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". 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.
