Hungary sent delegations to both Italy and Germany. Count Csáky went to Rome. Kálmán Darányi went to Germany and told Hitler that Hungary was ready to fight and " not accept the behavior of the Slovaks". However, the situation in Central Europe changed after the Munich Agreement and the German-Hungarian-Polish bloc was over. Germany refused to take steps to strengthen Hungary. Hitler declared that if Hungary started a conflict, nobody would help. He refused the idea of a common conference of the four signers of the Munich Agreement, the demands for plebiscite in Slovakia and Carpathian Ruthenia and the Hungarian claims for Bratislava. Instead, he advised Hungary to continue the negotiations and to preserve the ethnic principle. He proposed that Germany would act as a mediator. Ribbentrop and Darányi agreed on a map which would be offered to Czechoslovakia ("Ribbentrop line"). The line later became source of misunderstanding between Hungary and Germany. According to Darányi, Ribbentrop did not accept his requests because several important towns remained on the Czechoslovak side (Bratislava, Nitra, Uzhorod and Mukachevo; the question of Košice was open). Germany rejected the accusations and declared that Ribbentrop line was created after consulting Darányi and with his agreement. When the Hungarian government insisted, Ribbentrop announced that German mediation had ended.
