diocese was only Polish-occupied German territory. Afterwards, in a private conversation, Hlond urged Kaller to resign which he did for the jurisdiction in the Polish-occupied diocesan area, but retained the office of Bishop of Ermland, which rather turned quite void, especially since in the Soviet-occupied diocesan area no Catholic ecclesiastical activity whatsoever was tolerated. Later in Poznań, Hlond praised Kaller for how he had complied with the demanded resignation from jurisdiction. On his way back, accompanied by Borowiec, Kaller cried and told him that the jurisdiction in the Polish-occupied diocesan area would be passed on to Teodor Bensch, a German-born naturalised Pole, who would arrive within days officiating as apostolic administrator. They returned home in the evening on 16 August. Kaller could not appoint the four new canons for the chapter any more but was expelled the next day, transferred by lorry to Warsaw, accompanied by Borowiec, who also joined him on the train to Poznań on 18 August. Then Borowiec, who had not been expelled, returned to the diocese, while Kaller had to leave via Stettin for Allied-occupied Germany. Kaller's last years Kaller found asylum in what became Bizone in 1947. On 26 September 1946, Pius XII appointed him Papal Special Commissioner for the homeland-expelled Germans (). In November 1946, Pius XII invited Kaller to Rome. Both were personally acquainted since their common time in Berlin (Pius as Nuncio to Germany and Kaller as priest), and the latter reported to the pope on the destitute situation of the expellees from eastern Europe. On 7 July 1947, Kaller died suddenly of a heart attack in Frankfurt am Main and was buried besides St. Mary's Church in Königstein im Taunus. Succession of Kaller until 1972 On 11 July 1947, the Ermland chapter, residing in the Allied Bizone, then elected Provost Arthur Kather (1883–1957), officiating before his exile at St. Nicholas Catholic Church in Elbing (today's Elbląg), capitular vicar, as provided by canon law in case of sede vacante. The Holy See later confirmed him and thereafter Kather represented Ermland diocese in the Fulda Conference of Bishops until his death. On 29 July 1957, the Ermland chapter, with the surviving capitulars living in what had become West Germany, elected Hoppe as capitular vicar, who had been expelled from the Soviet-occupied Ermland diocesan area (Kaliningrad Oblast) in 1947. Hoppe held that post until Pope Paul VI terminated the apostolic administration of Ermland diocese
