Note: Inspired by a reader, in this post I investigate the location of a Polish forced labor camp situated near Kamenz, Germany [today: Kamieniec Ząbkowicki, Poland], a place I’ve discussed in several earlier posts. Determining its location caused me to examine the purpose of the various networks of underground caves and subterranean structures the Nazis constructed in the latter stages of WWII in the mountainous regions of Germany, Austria, and Poland.

POST 114: EDWARD HANS LINDENBERGER, A DISTANT COUSIN: MIGHT HE HAVE SURVIVED BUCHENWALD?
A gentleman, Mr. Wayne Lewan, from New South Wales, Australia recently contacted me through my blog regarding his father, Zbigniew Lewandowski. Wayne’s surname is obviously a truncated version of his ancestors’ family name. He happened upon several recent blog posts I wrote about Castle Kamenz [today: Kamieniec Ząbkowicki, Poland] that my friend Peter Albrecht von Preußen’s family owned through several generations.
Wayne sent me two pages (Figures 1a-b) documenting that his father had indeed been a forced laborer in Kamenz in Silesia near Breslau [today: Wrocław, Poland] between 1944-1945, when Silesia was part of Germany. I found these and other pages, including Zbigniew Lewandowski’s photograph (Figure 2) on his 1948 “Application for Assistance” requesting help to immigrate to Australia, in the online Arolsen Archives database. This database has the largest collection of information on Nazi victims, including documents on concentration camps, forced labor and displaced persons.
According to Wayne, his father was picked up by the Nazis in a street roundup in Warsaw on the 17th of July 1944. Given the timing of his arrest, it is likely that Zbigniew was arrested during the Warsaw Uprising, the World War II operation by the Polish underground resistance to liberate Warsaw from German occupation. It occurred in the summer of 1944, and it was led by the Polish resistance Home Army. Following Zbigniew’s arrest, he was held in Kamenz between July 1944 and January 1945, then moved to Mühldorf, a subcamp of the Dachau concentration camp located near Mühldorf in Bavaria, where he was liberated in May 1945.
Aware that present-day Kamieniec Ząbkowicki, Poland, located in the Lower Silesian Voivodeship (i.e., an “administrative district”) of south-western Poland, has a population of only about 4,200 people today and is a small community, I became curious as to where exactly in Kamenz the internment camp might have been located.
For geographic reference, Kamieniec Ząbkowicki is approximately 80 miles northwest of Racibórz (Figure 3), where my father was born, and roughly 50 miles south of Wrocław, Poland [formerly: Breslau, Germany]. (Figure 4) Wrocław is a city in southwestern Poland and the largest city in the historical region of Silesia. Kamieniec Ząbkowicki is an important railroad junction, located on the main line which links Wrocław with Kłodzko [Glatz, Germany] and Prague.
The reason the location of a forced laborer camp in Kamenz is so fascinating is that in the numerous discussions I’ve had with Peter Albrecht von Preußen the existence of such a purported camp has never previously come up. And, in fact, the document Wayne Lewan sent me merely indicated his father had been interned in “Kamenz, Schles., near Breslau,” (see Figure 1a) making no allusion to Castle Kamenz proper. Still, while my online research yielded no mention of any forced laborer camp near Kamenz in Silesia, I confusingly discovered there had been a concentration camp in another town by the same name located in Saxony; the latter was a subcamp of the Gross-Rosen concentration camp.
I began to wonder whether an internment camp might have existed underground near Castle Kamenz. While researching this possibility, I learned that the Nazis had begun a secret construction project in the Owl Mountains [Polish: Góry Sowie; German: Eulengebirge] beneath Książ Castle, located only about 43 miles northwest of Castle Kamenz. Książ Castle is a castle in northern Wałbrzych (Figure 5) in Lower Silesian Voivodeship, Poland, and the largest castle in Silesia. It stood to reason that if the Nazis had begun fabrication of massive underground bases beneath a nearby castle in Silesia, they might have done the same beneath Castle Kamenz. Nonetheless, Peter Albrecht confirmed that a similar assembly project had never been built under Castle Kamenz.
The project underneath Książ Castle was code named “Project Riese” and involved the construction between 1943 and 1945 of seven massive underground bases. The purpose of this vast subterranean network project remains uncertain. Some sources suggest that all the structures were part of the Führer Headquarters; according to others, it was a combination of headquarters (HQ) and arms industry, with Książ Castle intended as an HQ or other official residence, and the tunnels in the Owl Mountains planned as a network of underground factories. The tunnels were never finished though thousands of prisoners of war, forced laborers, and concentration camp inmates worked and died during the construction work.
In any event, the revelation of underground bases the Nazis excavated or natural caves or old mines they expanded upon has opened a plethora of topics I’ve either never previously discussed or only touched upon. They relate to the final phase of WWII when their development was widespread throughout the mountainous areas of Germany, Austria, and Poland and widely involved the use of forced laborers, prisoners of war, and concentration camps inmates. Because they often lack documentary evidence, they invite endless speculation as to their true function. I will briefly explore some of these issues.
Let me begin by discussing what I learned from Peter Albrecht as to the presumed location of the forced labor camp in Kamenz vis a vis Castle Kamenz. Some of Peter’s information comes from an informant named Stefan Gnaczy who started the local historical society and the small museum in Kamieniec Ząbkowicki; regrettably, Stefan passed away in 2019, though his son Matthew Gnaczy continues to be involved with the historical society and museum.
Before relating what Peter has learned about the forced labor camp near Castle Kamenz let me review some of what I presented to readers in Post 135 for context. Peter’s great-great-grandfather Friedrich Wilhelm Nikolaus Albrecht von Preußen (1837-1906) was gifted Castle Kamenz by his mother upon his marriage to Princess Marie of Saxe-Altenburg (1854-1898) in 1873. Shortly thereafter he started to build a large steam boiler house (Figure 6); the source of heat for a boiler is typically combustion of any of several fuels, such as wood, coal, oil, or natural gas. It’s unknown to me which of these fuels was used to create the steam, though underground pipes running through a tunnel connecting the boiler house to the castle are known to have carried the steam between the two.
Upon Nikolaus’ death in 1906, Castle Kamenz was inherited by his eldest son, Friedrich Heinrich von Preußen (1874-1940), mentioned in several earlier posts. Beginning around this time, he converted approximately 50 rooms into apartments and outfitted them with baths, telephones, radios, and electricity. By then, the boiler house had an electric generator and the tunnels now carried not only steam but electricity. The significance of this will soon become clearer.
Prior to Friedrich Heinrich’s death in 1940, he sold Castle Kamenz to his second cousin, Waldemar von Preußen (1889-1945), who owned the castle throughout WWII.
According to what Peter has learned from local residents of Kamieniec Ząbkowicki as well as the historical society, there is a tunnel/cave system running below the town that is at least six miles long, perhaps longer depending on who you believe. Purportedly, the system was developed hundreds of years earlier for unknown reasons by monks from the former Kamieniec Abbey, which still stands but was secularized in 1810. The caves and tunnels thus predate Castle Kamenz which was constructed between about 1838 and 1872.
Part of this web of tunnels and caves may have included the adits of the former gold and arsenic mine located in Złoty Stok [German: Reichenstein, Germany] mined in the Middle Ages, located a mere 6.1 miles south of Kamieniec Ząbkowicki. (Figure 7)
Peter was able to discover there was indeed a forced work camp near Kamieniec Ząbkowicki at a place formerly call Reichenau, Germany [today: Topola, Poland], located 3.6 miles southeast of the castle. (Figures 8a-b) Topola is a village in the administrative district of Kamieniec Ząbkowicki.
The source of the information on Topola is a report prepared by the Lux Veritatis Foundation, based in Warsaw, called “The Compilation of Places of Crimes Committed against the Civilian Population by the Nazi Occupant on the Polish Territories in Years 1939–1945.” According to Volume 3 of this compilation entitled “The Report on the Losses Sustained by Poland as a Result of German Aggression and Occupation During the Second World War, 1939–1945” (Figure 9) which includes a “List of Atrocity Sites,” 82 Polish citizens, including Poles, Jews, and Romanis, were murdered in Topola during its existence, likely from the extremely harsh and tortuous working conditions. (Figure 10)
The Lux Veritatis’ “List of Atrocity Sites” was compiled based on the work of the Central Commission for the Investigation of German Crimes Committed in Poland. According to the report, “Each volume contains the records of Nazi German atrocities committed in a particular voivodeship (according to the territorial administrative division of Poland in the 1970s), and presents the facts and figures as known to Polish scholars in the 1980s and up to the early 1990s. This series of volumes does not include data on Nazi German concentration and death camps, POW camps, or atrocity sites on territories now beyond the borders of Poland.”
The report further states the following as to the vast scale Nazi Germany’s efforts to exterminate the people of Poland: “Polish citizens were killed in individual incidents of murder, in mass executions by firing squad, during raids to ‘pacify’ whole villages, butchered while held in German prisons, hanged on the gallows in public executions, or slaughtered in barbaric atrocities of miscellaneous other types. Victims included women and children as well as persons with no connection at all with the circumstances triggering an atrocity, who just had the bad luck to be there when the killing started. The German authorities occupying Poland pursued a policy of collective accountability and executed ‘hostages’.”
Given Topola’s proximity to Castle Kamenz and the estimated extent of the nearby tunnel/cave system beneath Kamieniec Ząbkowicki, Peter knows the Nazis tapped into the electric grid and also siphoned off steam from the castle’s electric generator and boiler house to power whatever activities they were clandestinely pursuing. Naturally, this left the castle with limited electricity and steam.
The boiler house tunnel system is currently undergoing restoration, and Peter sent several photos of the ongoing work. (Figures 11a-f) Clearly, the tunnel system once connected to the larger web of subterranean tunnels and caves that were part of the Topola network, though the photos confirm the juncture was sealed off. Apparently, this was done in 1947 by Poland’s Communist government in a covert operation.
Peter emphasizes, however, that in the time that his ancestor Prince Waldemar owned the castle during WWII no forced laborers were used in the operation of Castle Kamenz’s operations nor were any interned in the boiler house tunnel system since the latter is too narrow.
The absence of documentary materials about Reichenau and, more generally, the question on what purpose the various secretive Nazi bunkers and subterranean bases served, invites further examination and speculation.
According to Peter’s informant, the forced laborers that lived and worked in the underground bunker or cave in Topola (Reichenau) may have been gulaged by the infamous Organization Todt (OT). This organization was a civil and military engineering group in Nazi Germany from 1933 to 1945, named for its founder, Fritz Todt, an engineer, and senior member of the Nazi Party. Incidentally, Todt was responsible for the construction of the German autobahns.
OT had oversight for a huge number of engineering projects both in Nazi Germany and in occupied territories from France to the Soviet Union during WWII. The organization became notorious for using forced labor. From 1943 until 1945 during the late phase of the Third Reich, OT administered all constructions of concentration camps to supply forced labor to industry.
Todt was killed in February 1942 near Rastenburg when his aircraft crashed shortly after take-off. He was succeeded as Reichsminister and head of the OT by Albert Speer. This coincided with the absorption of the organization into the renamed and expanded Reich Ministry of Armaments and War Production. Approximately 1.4 million laborers were in the service of the organization. About one percent were Germans excused from military service, another 1.5 percent were concentration camp inmates, and the remainder were prisoners of war and forced laborers from occupied countries. Many of the laborers did not survive the arduous work which they were condemned to.
Suffice it to say, that according to the United States Holocaust Memorial Museum website, “Between 1933 and 1945, Nazi Germany and its allies established more than 44,000 camps and other incarceration sites (including ghettos). The perpetrators used these locations for a range of purposes, including forced labor, detention of people deemed to be ‘enemies of the state,’ and mass murder.”
It is possible, and indeed likely, that if forced laborers were used for whatever activities were being undertaken in the tunnel and cave system at Topola, the OT might have brought the needed workers from concentration camp Gusen (Figure 12), located three miles from Mauthausen concentration camp, and 280 miles south-southwest of Kamieniec Ząbkowicki. Recall that Kamenz was a major railway hub to Breslau and Prague, the latter 153 miles directly north of Gusen.
A possible clue as to what clandestine activities may have been going on beneath Topola is the presence of a high-ranking Nazi official named Hans Kammler who is reputed to have maintained a residence in Kamieniec Ząbkowicki after 1943. Hans Kammler was an SS-Obergruppenführer (translated as “senior group leader,” the highest commissioned SS rank after only Reichsführer-SS) responsible for Nazi civil engineering projects and its top V-weapons program. He oversaw the construction of various Nazi concentration camps before being put in charge of the V-2 rocket and Emergency Fighter Programs towards the end of WWII.
V-weapons formed part of the range of the so-called Wunderwaffen (superweapons, or “wonderweapons”) of Nazi Germany, and were intended to be used in a military campaign against Britain, although only the V-1 and V-2 were ever used against them. The V-2 and other German guided missiles and rockets were developed by the Peenemünde Army Research Center (German: Heeresversuchsanstalt Peenemünde, HVP).
Britain’s RAF successfully bombed the Nazi’s rocket production facilities at Peenemünde in August 1943 in Operation Crossbow. Following this successful raid, Albert Speer recommended transferring the V-2 rocket production underground. Hitler immediately agreed, and he and Speer decided that the SS, with its access to a massive supply of slave labor, was best suited to undertake this task.
As the SS construction chief, Hans Kammler was selected to oversee the project. The secret weapons projects for which Kammler was given responsibility included manufacturing both the Messerschmitt Me 262, the first operational jet fighter, and the V-2, which Kammler—in a construction effort of ruthless brutality and speed—had in production before the end of 1943.
The first below-ground project began at a huge fuel storage facility in the German state of Thuringia. By late August 1943, Kammler had a sizable detachment of concentration camp inmates from Buchenwald working at the new underground installation. There were so many slave laborers by the end of 1943 that the subcamp of Mittlebau-Dora was established. The latter supplied slave labor from many Eastern countries occupied by Germany (including evacuated survivors of eastern extermination camps), for extending the nearby tunnels in the Kohnstein and for manufacturing the V-2 rocket and the V-1 flying bomb. Gypsum mining in the hills in the Kohnstein had created tunnels that were ideally suited as a fuel/chemical depot and for Nazi Germany factories, including the V-2 rocket factory.
Regular readers may recall Post 114 and Post 114, Postscript where I discussed one of my distant cousins, Edward Hans Lindenberger, who was compelled to work in the underground tunnels near Buchenwald and Mittlebau-Dora and was never heard from again, no doubt a victim of the Nazis policy of working concentration camp inmates to death.
Assuming the accounts of Hans Kammler’s presence in Kamieniec Ząbkowicki after around 1943 are credible, given the responsibilities he was assigned by Hitler and Speer, it is reasonable to assume that he was engaged in preparing the caves around Topola to produce secret weapons. The mounting pressure on the Nazis from the Allies as the war proceeded suggests that most of the planned underground bunkers and caves were never completed. Pictures of the unfinished bunkers that were part of Project Riese, for example, show old winches, abandoned munitions carts, and primitive railway tracks leading into the tunnels, but not enough to conclusively determine what activities were planned.
In the absence of documentary evidence, one can only surmise what the network of caves, tunnels, bunkers, and subterranean structures scattered throughout Germany, Poland, Austria, and elsewhere were developed for. Likely, they were intended for a range of different purposes, including production of munitions, planes, and missiles; headquarters from which to direct troop movements; places to house batteries of cannons; safe havens from which to make a last stand; and even locations to stash war plunder. What I find mystifying is that among the myriad Nazi documents that survived WWII, seemingly few related to the purpose of the underground caves exist. Either they were never produced, which seems unlikely, destroyed before the Allies could get their hands on them, or carted off by the Allies and are still classified.
Fascinatingly, treasure hunters have expended a lot of time, money, and effort exploring and radar scanning from above searching for underground cavities where a “Nazi gold train” rumored to contain 300 tons of gold, diamonds, other gems, and industrial equipment may have been hidden. According to legend, the train was loaded by the Nazis and entered a tunnel in the mountainous Lower Silesian region before Soviet Army Forces closed in, but the train was never seen again. There are periodic reports in the media about treasure seekers claiming to have found evidence of this train. According to Peter, the tunnels connecting Castle Kamenz to the boiler house are periodically broken into by fortune hunters seeking this chimera.
There is another factor complicating understanding the purpose of the various subterranean structures, namely inaccessibility and/or flooding of the chambers. In the case of Reichenau, the Neisse River runs through it. To the southwest of the site there was once a quarry. According to Stefan Gnaczy, Peter’s informant, in 1947 the Polish government sealed off the entrance to the caves and tunnels and flooded the quarry including the sealed entrance diverting water from the Neisse River. Stefan further claims to have found an unpublished Polish government report from the 1960s stating that only half of the underground tunnel is accessible for exploration, with the remainder flooded.
Coming full circle back to Wayne Lewan’s father. According to his father’s records, he was stationed in Kamenz for only about six months. It’s not clear why he was moved from Kamenz to Dachau concentration camp in January 1945. His pre-war occupation was telephone lineman mechanic, and perhaps he was considered a skilled worker whose abilities were better utilized in Dachau. (Figure 13) Regardless, alerted to the fact that Zbigniew Lewandowski had once been interned in Kamenz led me to track down the camp where he was likely held and to investigate Nazi underground bases and tunnels, the purpose of which remain shrouded in mystery.
