leave the country. The Polish government had relocated to the south-eastern town of Kuty on 17 September 1939 and held a cabinet meeting at 4pm, in full knowledge that Soviet forces were advancing rapidly towards them. It was concluded that they should cross the border into Romania, and from there go on to France. Most of Poland's highest government officials evacuated to Romania on the night of 17–18 September. The Soviet invasion destroyed the possibility of any further coordinated military action by Poland against the Germans. Nevertheless, the Poles kept on fighting - the last significant battle which organised Polish forces took part in was at Kock, which ended on 6 October. The Polish government refused to surrender or negotiate a peace, and instead ordered all units to evacuate Poland with the aim of eventually reorganising in France. The Soviet invaders were met with only sporadic resistance, most notably in the Battle of Szack when Polish artillery wiped out an entire brigade of Soviet tanks. The Soviet Union lost 1,500 men during the invasion.

They sent an army group, called Field Army Bernolák under the command of Slovak General Ferdinand Catlos. Their campaign began on September first, 1939. They occupied the Polish town of Tatranska Javorina and several other Polish areas (which are still part of Slovakia today.) They only faced one Polish force, the Karpaty Army. At the end of their attack, they had occupied much of Southern Poland with the cost of only 37 men killed and 114 men wounded.
