Below is a list of some German and Austrian priests arrested or harmed by the Nazis whose names and stories I have come across in the course of my research. I must stress that it is not comprehensive. I do not even claim that it is completely accurate. Although I have repeatedly crosschecked and verified the information contained in it, many tricky problems stand in the way of establishing an exhaustive, accurate list.
For one thing, Hitler redrew Germany’s borders and he redefined Germanness. So, it is not even completely clear who was actually a German priest and who was not during the Third Reich. For instance, Alsatians and Luxembourgers, not to mention Austrians, were among those who became members of the master race during those days, whether they liked it or not. So it is that, for example, the Alsatian Dachau survivor Fr. Jean Kammerer and the Luxembourger Dachau survivor Fr. Jean Bernard and their compatriots do not figure on the list below, although the Nazis considered them to be German priests.

In addition, errors in the names of priests mar records, journalistic accounts and other writings by them and about them. Names were liable to be misspelled, for instance, umlauts not taken into consideration. In addition, there are often variations in the spelling of German names, for example: Karl and Carl; Johannes, Johann and Jan; Rudolf and Rudolph; Heinrich and Heinz. Moreover, priests belonging to religious orders often had both religious and legal names and therefore could be known and remembered in completely different ways, something I have indicated, when I could, by placing religious names in parentheses.
It also happened that many priests were arrested more than once and many were held in several different jails, prisons and concentration camps, and so the same priest’s name could appear in different records and even appear in them in various forms and with variant spellings. Then, when arrested or harmed priests made international news, they were not always named. In addition, not all priests declared themselves as such. Fr. Lenz estimated that there were about 150 priests, presumably of all nationalities, who revealed that they were priests in Mauthausen concentration camp when he was there, but that a number of other priests did not out of fear of being subjected to even harsher treatment. (Lenz 1957, 61)

All these, and undoubtedly many other, factors leave room for error. So in spite of my efforts to verify the information and to correct disparities and discrepancies, it is absolutely certain that mistakes remain. However, my point is that, despite the obstacles standing in the way of making an exact, completely comprehensive list of priests victimized by Nazi henchmen, it is very easy to show that hundreds, even thousands, of German and Austrian priests were arrested, imprisoned, beheaded, shot, tortured, hanged, shot, gassed or otherwise euthanized, starved to death, used as guinea pigs, worked to death, injected with poison or merely exiled or locked up in concentration camps or otherwise harmed by Nazi henchmen.

Besides the names appearing in the Newsreel of the previous chapter and found in other secondary literature that I consulted, this list was mainly compiled from information found in Als Priester in Konzentrationslager (Arthofer 1947); Priester unter Hitlers Terror (Hehl et al eds. 1998); Priester vor Hitlers Tribunal (Kempner 1996); Zeugen für Christus, Das deutsche Martyrologium des 20. Jahrhunderts (Moll ed. 2014); the Documentation Centre of Austrian Resistance (DöW) online; Errinerungen eines katholischen Geistlichen aus der Zeit seiner Gefangenschaft 1941-45 (Carls 1945); Oldenburgs Priester unter NS-Terror, 1932–1945 (Hirschfeld & Zumholz eds. 2006); Prêtres allemands à Dachau (Münch 1977); Priester im Dritten Reich (Würth 1992). …And Who Will Kill You contains an almost 300 page list of priests of all nationalities who were in Dachau (Hoffmann 1946, 287-581). Christus in Dachau also contains a long list. (Lenz 1957, 419-26)
In drawing up this list, I have adhered to Sereny’s criteria of being arrested, harmed, German or Austrian and a priest. Bishops, archbishops, nuncios and cardinals are also priests and several were arrested or harmed, but accounts of their ordeals figure in another chapter. Members of religious orders with the title “Brother” are usually not priests, so I have not included them, nor have I included the seminarians, women religious, or the dozens of Protestant ministers persecuted by the Nazis, though they certainly deserve to be remembered. I have also left out the many priests who were merely interrogated, stalked, harassed, threatened, insulted, hounded, humiliated by the Nazis, but not arrested or otherwise harmed.

Not figuring in the list, but not to be forgotten, are the thousands of non-German and non-Austrian priests whom Nazi underlings sent to the many camps they established. Roughly 2,670 priests, from Albania, Belgium, Croatia, Czechoslovakia, Denmark, England, France, Greece, Holland, Hungary, Italy, Norway, Poland, Romania, Serbia, Slovenia, Spain, Switzerland and other countries have been documented as having passed through Dachau alone, where over a thousand of them left their lives (Kammerer 1995, 70). According to Actes et Documents du Saint-Siège relatifs à la Seconde Guerre Mondiale, on October 17, 1942, Bishop von Preysing sent the following statistics to the Vatican about priests who had died in Dachau during the three months between May and July 1942: in May 1942, 35 priests died, 34 of whom were Polish; in June 1942, 119 priests died, 110 of whom were Polish and 5 were German; in July 1942, 174 priests died, 160 of whom were Polish and 8 were German (ADSS vol. 2, p. 325, n. 16). A priest so unfortunate as to come from certain countries, for example, Poland, Slovenia, the Baltics, the Ukraine, could well enough have been killed on the spot, leaving no record to show for it.
