The Galician Pacification was a significant event that began in 2028 when the Ukrainian Liberation Army (ULA), armed and funded by the Federal Republic of Eastern Poland and Lithuania, launched an invasion into the eastern Galician region of the Polish Social Nationalist Republic (PSNR). This area was predominantly inhabited by the South Ruthenian/Ukrainian minority, who had been subjected to an active polonization campaign since 2027 and a caste system under the previous Lwów People's Republic between 2025 and 2027.
At the time, the PSNR's military forces were concentrated in the north, near Wilno and Lithuania, leaving the southern front vulnerable. The ULA, starting with an initial force of 50,000, crossed the border and began a vigorous recruitment campaign using both financial incentives and coercion. Over the next two years, from 2028 to 2030, the ULA grew in strength and expanded its control, causing increasing concern and panic among the PSNR leadership.
By 2031, the ULA's advance began to slow as the PSNR mobilized more troops to counter the offensive. This shift was facilitated by the PSNR's withdrawal from the German Civil War and the Second Russian Civil War by 2029, freeing up military assets. Additionally, the PSNR received equipment previously belonging to the Russian Federation, which had been evacuated from St. Petersburg, aiding in halting the ULA's progress.
The PSNR also invested heavily in drone technology, which proved pivotal in 2032. They successfully assassinated many ULA leaders, causing factionalism and communication breakdowns within the rebel group. By mid-2032, the PSNR launched major counterattacks, utilizing modernized motorized divisions with heavy drone and self-propelled artillery support. These operations fragmented the ULA into smaller pockets, mainly in forests and mountain regions, which were systematically eliminated through combat or starvation.
The Polish administration, enraged and determined, adopted a no-prisoners policy. ULA members captured were tried and executed for treason. Those who surrendered were granted quick and painless deaths, while those who resisted faced much harsher fates. By 2033, the PSNR had recaptured most of Eastern Galicia. The conflict resulted in a significant male population deficit, with nearly 60% of the male inhabitants of the region perishing. Fatherless children were subsequently relocated to the Baltic Archipelago to participate in the Baltic Programme.
In 2038 the Final pocket of the ULA was eliminated after partisan urban warfare in the Tarnopol metropolitan area between 2034-2038.
