in those areas annexed to Germany. In the territories annexed to Greater Germany, the Nazis set about systematically dismantling the Catholic Church - arresting its leaders, exiling its clergymen, closing its churches, monasteries and convents. Many clergymen were murdered. Elsewhere in occupied Poland, the suppression was less severe, though still harsh. The Papal Nuncio to Poland, Fillipo Cortesi , had abandoned Warsaw along with the diplomatic corps, after the invasion. Other channels existed for communications, including Cardinal Hlond. On 18 September 1939, at the request of the Polish Government, Hlond left Poland, with part of the Army, in order to reach Rome and report on the actions of the Nazis in Poland, and inform the world via Vatican radio and press. Hlond submitted an official account of the persecutions of the Polish Church to the Vatican, reporting seizures of church property and abuse of clergy and nuns in the annexed regions: In his final observations for Pope Pius XII, Hlond wrote: In 1939 Hlond spent several months in Rome for the conclave of 1939. In January 1940, Vatican Radio broadcast Hlond's reports of German persecution of Jews and the Catholic clergy in Poland. These reports were included in the report of the Polish government to the Nuremberg Trials after the war. In March 1940, Hlond went on a pilgrimage to Lourdes, in France. Following the Fall of France, he remained in the country, staying at the Benedictine Abbey at Hautecombe, in Savoy, where remained, unable to leave, until Himmler ordered the Gestapo to arrest him in February 1944 (the only member of the Sacred College of Cardinals to be arrested by the Nazis). The Gestapo held him at their headquarters in Paris for two months, and, with the Soviet armies now driving the Nazis back from Russia, attempted to have him declare public support for the German war against the Soviet Union, in order to secure his release. The Gestapo offered to make Hlond Regent of Poland, but, according to The Tablet, "The withdrawal of all German troops from Poland was necessary, the Cardinal implacably insisted, before he could even discuss any matter whatsoever with a German officer." Hlond remained in the custody of the Gestapo, first at a convent at Bar-le-Duc, until the Allied advance forced the Germans to shift him to Wiedenbrtick, in Westphalia, where he remained for seven months, until released by American troops in 1945.
