The Romanians disregarded the guarantees of the French leadership and remained on the eastern banks of the Tisza River. The Hungarian government claiming to impose the will of the Allies on Romania, and seeing that diplomatic solutions would not compel them, resolved to clear the threat by military force once and for all. They planned to throw the Romanians out of Tiszántúl, destroy the Romanian army, and even retake Transylvania. However, the Hungarian offensive was defeated by the Romanian army, and despite all previous pledges, agreements, and guarantees, the Romanians crossed the river Tisza and quickly advanced towards Budapest. The Hungarian capital fell on August 4, only three days before Kun's escape to Vienna. The destruction of the Hungarian Soviet Republic and the Romanian occupation of parts of Hungary proper, including its capital Budapest in August 1919, ended the war. Romanian troops withdrew from Hungary in March 1920, after seizing large amounts of goods from Hungary, which they regarded as war reparations.
