From 4 to 7 November 1938, thousands of Jews were deported from Slovakia to the no-man's land on the Slovak−Hungarian border. Following Hungarian territorial gains in the First Vienna Award on 2 November, Slovak Jews were accused of favoring Hungary in the dispute. With the help of Adolf Eichmann, Slovak People's Party leaders planned the deportation, which was carried out by local police and the Hlinka Guard. Conflicting orders were issued to target either Jews who were poor or those who lacked Slovak citizenship, resulting in chaos.
Many of the deportees managed to return home within a few days, but more than 800 were left in tent camps near Miloslavov, Veľký Kýr, and Šamorín in the no man's land along the border for months with some groups staying until January or February 1939. Another several hundred Jews were deported from Hungary to the no man's land. In the meantime they endured winter weather with little or no shelter, although they were helped by Jewish organizations in Bratislava. The deportations were a fiasco for the Slovak People's Party leadership, worsening the country's reputation abroad and causing capital flight by frightened Jews who intended to emigrate, but they were a preparation for the 1942 deportations to the ghettos and extermination camps in German-occupied Poland.
