Who lost the Polish–Ukrainian War?
Polish–Ukrainian War
In attempt to end the war, in January 1919 an Allied commission led by a French general was sent to negotiate a peace treaty between the two sides, prompting a ceasefire. In February it recommended that the West Ukrainian People's Republic surrender a third of its territory, including the city of Lviv and the Drohobych oil fields. The Ukrainians refused, the truce did not correspond to ethnology of the country or the military situation and broke diplomatic ties with Poland.[55][63] In mid-March 1919, the French marshal Ferdinand Foch, who wanted to use Poland as an operational base for an offensive against the Red Army, brought the issue of Polish–Ukrainian war before the Supreme Council and appealed for large-scale Polish-Romanian military operation which would be conducted with Allied support, as well as sending Haller's divisions to Poland immediately to relieve Lviv from Ukrainian siege.[59]
