On 22 June 1941, Germany attacked the Soviet Union. Four days later, the Hungarian city of Kassa (present-day Košice in Slovakia) was bombed by three unidentified aircraft. One bomb failed to explode and was found to be of Soviet origin. The Hungarian military concluded that the Soviet Union was responsible (this was denied, and the question of responsibility has never been satisfactorily resolved). When Bartha and Werth became aware of the bombing, they went to Horthy who ordered retaliatory measures without consulting Bárdossy. However, Bárdossy believed that Horthy wanted war with the Soviet Union, so he hurriedly assembled the Council of Ministers. In summing up the meeting, Bárdossy said that they were agreed that reprisals were necessary, and with the exception of Keresztes-Fischer, that they agreed that Hungary was now at war with the Soviet Union. The following day, Bárdossy stood up in Parliament and declared the attack had been by the Soviet Union, and that the government had decided that a state of war existed between Hungary and the Soviet Union. Horthy subsequently claimed that Bárdossy had presented him with a "fait accompli".
