plans were changed: it was decided irrevocably to transport our army to Gdańsk instead by trains, through Germany. Many officers came from Poland, among them Major Gorecki, to coordinate technical details with General Haller. Polish–Ukrainian War Haller's troops changed the balance of power in Galicia and Volhynia. Their arrival allowed the Poles to repel the Ukrainians and establish a demarcation line at the river Zbruch on 14 May 1919. The Blue Army was equipped by the Western Allies, and supported by experienced French officers specifically ordered to fight against the Bolsheviks in the Polish–Soviet War, but not the forces of the Western Ukrainian People's Republic. Despite the diplomatic conditions, the Poles dispatched Haller's Army against the Ukrainians first, instead of the Bolsheviks. The tactical initiative was done in order to break the stalemate in eastern Galicia. In response, the allies sent several telegrams ordering the Polish government to halt its offensive, as using the allied-equipped army against the Western Ukrainian People's Republic specifically contradicted the status of the French military advisors, but the demands were ignored. The offensive by the Blue Army succeeded in breaking the stalemate and brought about a collapse of the West Ukrainian army. In July 1919, after securing victory on the Ukrainian front, the Blue Army was transferred to the border with Germany in Silesia, where it prepared defensive positions against a possible German invasion of Poland from the west. Polish–Bolshevik War During the Polish-Bolshevik War several Blue Army formations were merged with the regular Polish army, and jointed together to form the 49th Hutsul Rifle Regiment and 18th Infantry Division. Haller's well trained and highly motivated troops, as well as their British built Bristol F.2 reconnaissance planes, Italian made Ansaldo A.1 Balilla fighter planes and French FT-17 tanks, also played a significant role in the war. The Polish-American first engaged the Bolshevik forces near the town of Rivne (Równe in Polish) on 18 June 1919. After pushing the Bolsheviks east, the Blue Army advance halted and the troops engaged in small skirmishes until the end of the war. Haller's troops would try to entrap small units of Bolshevik soldiers as well as raid garrisons for food, ammunition and to spread panic amongst the enemy. Post-war The Blue Army's 15th Infantry Rifle Regiment formed a basis for the 49th Hutsul Rifle Regiment (part of the 11th Carpathian Infantry Division) after the end of World War I.
