On March 17, 1944, Regent Horthy was "invited" to a conference with Hitler, who informed him of the imminent occupation of Hungary by German troops. Horthy had to agree to Kallay's dismissal. The aerodromes of Budapest were seized by a German task force. A new Government was appointed under Sztojay. The Arrow Cross leader, Laszlo Baky, was appointed Undersecretary of State in the Ministry of Interior, and Laszlo Endre Administrative Under-secretary and expert on Jewish affairs. Veesenmayer was appointed as Ambassador to Hungary and as Plenipotentiary of the German Reich. Eichmann came to Budapest at the end of March. On March 29, 1944, it was decreed that all Jews must wear the yellow star. Concentration of all the Jews took place at a rapid pace. In May, the first deportation trains left for Auschwitz. At the end of June, 381,661 Jews had been deported. On July 9, 1944, the total number was 437,402. The evacuation of the Jews of Budapest was planned for July. <196> Concerted pressure was exerted on Regent Horthy to stop the deportations. Switzerland and Sweden made urgent requests. The Turkish and Spanish governments also intervened. The Papal nuncio was, according to Sztojay, calling "several times" a day. On July 6, Sztojay informed Veesenmayer that the Regent had given the order that the deportations should stop. In fact, the stoppage occurred in the middle of July and it lasted until October. On April 3, 1944, Bishop Laszlo Ravasz addressed a letter of protest to the Minister of the Interior. In this document Bishop Ravasz did not object to the stigmatization of the Jews, but to the regulations that required members of the Reformed Church to wear the star of David. [437] At the same time he called on Ambrozy, the Regent's chef de cabinet, and asked to be granted an audience with the Regent. He was informed that "the Regent regards himself a prisoner and will not receive anyone". Subsequently Bishop Ravasz called on the Minister of Interior, who asked him to return at 7 p.m. the same day. "Jaross, who kept the Bishop waiting till 8 p.m., agreed, after a heated argument, to exempt certain Church dignitaries and persons of Jewish origin who had contracted mixed marriages." [438] On April 6, the General Assembly of the Reformed Church addressed a petition to the Prime Minister, urging him to be mindful of the claims of humanitarian thinking, and demanding the extension of granting exemptions.
