The Red Army, under Vladimir Antonov-Ovseyenko, advanced southwards and conquered most of Podolia by April. The region was incorporated into the Ukrainian SSR; this new regime quickly restored the Bessarabian Brigade, but purged it of political suspects. During the early days of May, Antonov considered plans for immediately "freeing Bessarabia" by invading through Khotyn. He was finally dissuaded from ordering it by Romanian successes on the Hungarian Front, and by supply inadequacies. Ukrainian–Romanian skirmishes continued over several months, just as the Peace Conference began analyzing the eastern borders of Greater Romania. Atachi's inhabitants remained exceptionally hostile to Romanian rule, and Soviet soldiers felt encouraged to fire on Romanian positions during May 30; suspicions arose in Romanian circles that an "international battalion" was being trained to invade Bessarabia from Mohyliv.
